0:02 Hello everyone, good evening. How are you wherever you are? May you always be healthy, may you always be enthusiastic, may you always be aci kiwir wherever you are. Even though I'm wearing attributes like this, but guys, this isn't what that cireng was for 5,000. Are you a meatball or siomay seller, sis ? I'm a kidnapper. Astagfirullahalazim. When it comes to the halo record, it's really different. Of course. Let's act first, honey. The openings should always be sweet, but the inside is full of suffering. Morning, morning, morning. That's amazing, huh? I am not a scoutmaster. Scouts must not be afraid. Uh, what's that? I don't know. Where do you sell meatballs
0:48 , bro? Tulip squad. Tulip squad squad. Extraordinary. Oh, my God. 5 bowls of meatballs, bro. Yes, okay? Yes, you can. But a bowl is Rp. 50,000. Want you? Huh? Want to go fishing? There's more fishing, Sis. Group 6 would like to ask permission. No, you can't. No way. Group 6 didn't get any marks, right? Oh my, this is already using K. The tutor was bitten by a snake. Oh, my God. It's a shame that the tutor was bitten by a snake. It's nice to not want to. Okay, so tonight,
1:33 this beautiful night in West Jakarta right now, tonight I don't want to be alone. So, that's why I'm in the same class as you guys. Radit, how do you know? Raden, how do you know today's theme? Come on. How do you know? Wow, yes, it's true that he's become an animal. Because our theme today is horses and animals. Darling. So, our theme is wildlife, right? Later, if our material is about viruses, the theme will be COVID. So you turn into the Covid virus. Oh my, cosplay is so hard. Plantai wildlife animalianya darling. Is Animali cosplaying as a banana tree hawk? Hmm. Yes. Oh,
2:22 let's make it more exciting, shall we? Oh, wait a minute. Well, if our gimmick is like this, it will fall. Ah, it won't fit if we fall. So, if we do the gimmick, it will be even more exciting, right? It's a shame. Come on, fall. Come on, who wants to eat first? Who wants to be fed first? Come on, let me open this. Come on, who wants to eat first? Come on, yeah. So for our esteemed visitors, here is our collection. Oh, a collection of wild animals
3:07 that we will try to feed. Come on, open your eyes first, honey. Ah, mm, it's so delicious. Beware, beware of entering core biology. Eh, no core biology has been made. There won't be any more . In the chat column there is U I A Ui u a U I a ui u wa a. You are a codon. Ui a ui a aa. There is also Dedek Bagus eating pisicang. Yep, it's lame. But it's not finished, dear. We'll finish it later, okay? Not here of course. Eat the banana .
3:52 Ouch. Wait a minute. Dehydration again. Oh, Raden really turned into a scout. Okay, let it be. It's okay, it's okay. Hehe. He's going to start cheering soon. Want to shout support 3. Let it be. Okay. So today guys, today we are going to learn about animals and flora. Hooray. You guys have studied the material with Mas Mono yesterday, right? Two more meetings. There has been a special meeting for Animalia, there has been a special meeting for pelant. Well, here we join because we are focused on the practice, right, honey? Uh, let me share my screen first, Cinta. Hehe. Okay, the gimmicks will be easier later.
4:41 conqueror of the pelanti, tamer of the raur animals. Those are our words today, friends. Huh huh . Raden misses school. Yes, he was already wearing a scout uniform. What is that for, if I may ask? Raden Raden yes. The bonfire photo is the same again and again. Yeah, let people be funny. Why do you keep protesting? It's that photo again, it's that photo again. Later, if you replace it with Liminho, you will be surprised. Bonfire. Be patient, pat the scout first. Ah, how about I pat you all one by one. Oh, this isn't right, is it? There are alternative participants, yes. Huh huh
5:26 . Lord Bantara. Isn't Bantara a scout? Ah, that's enough for now, dear. Let's focus first. Focus on this when we look around. the audience decreases every night. Natural selection is real. But it's okay. Love love for those of you who always attend biology class. Uh yeah. Thank you to those of you who always attend biology class. Hopefully we will always have a lot of this. Oh, but I'm being honest, sometimes I like to get carried away because earlier, a lot of the bananas fell and I didn't pick them up. Oh dear, I'm going to close this chat now, it's a shame. Let's focus first on our material tonight, namely pelante and animalia. I want to
6:12 start with animalia first, friends . Let's start with animalia first. Animalia, aka the animal group. Well, in biology we are animalia, guys. We don't have our own kingdom. We don't have our own group, okay? So we are animals. Wow. Only in biology class can we say that we are animals. Well, the Animal Kingdom in general. In general. Well, here's how to read the table. The way to read the box is from left to right, that's a shame. So let's look at the far left. Sorry if I suddenly stopped talking, you know I was burping as usual. Yes, Gert. Let's start from the leftmost box, darling. These animals are generally
6:59 divided into two types. There are parazoa, there are parazoa, and there are eumetazoa. What's the difference? Parazoa are animals that do not have true body tissue . This means that the cells in the body seem to be able to work on their own. A bit individualistic, a bit selfish. Plus, the cells in the body can change into other types of cells . Yes, it's up to you. That's why it's said that he doesn't have true body tissue . Because real body tissue is a collection of cells that have similar structures, similar functions and they work together as a whole. But there are animals whose cells are somewhat selfish,
7:45 somewhat individualistic. Ugh, I don't want to work in a group, bye, I want to do it myself. Well, that's called a parazoan animal. There is only one parazoan animal on the face of the earth, my dear. Porifera. Porifera are sponge animals, yes. So, if you watch Spongebob Square Pants, well Spongebob is the Sponge animal, right? So, his body is full of pores , full of holes, right? And also, the shape of sponges is usually asymmetrical, right? This means it is irregular , there is no axis of symmetry, it cannot be cut into two equal sizes and shapes, that is not possible. So he is asymmetrical, has no body symmetry. But other animals, other animals besides sponges, other animals besides porifera, have real body tissues
8:31 . Well, that's what we call eumetazoa. Eumetazoa. Symmetrical dishwashing sponge , Sis. Dishwashing sponges are actually animals, not plastic. Eumetazoa. Eumetazoa is a group of animals that already have true tissue. So, the body's network is really solid. Native body tissue, yes. So, the cells work together for certain functions, right? There is skin tissue, there is muscle tissue, nerve tissue, blood tissue, wow, all kinds of things. Well, eumetazoa are all animals except porifera. Well, let's read it again to the right. Eumetazoa are divided into two groups. This is how to read it to the right.
9:20 Well, eumetazoa are divided into two groups, friends. Some have radial body symmetry, some have bilateral body symmetry . Radial body symmetry is when the animal's body has many axes of symmetry. Come on, this is just a little elementary school math. What is an axis of symmetry? The axis of symmetry is a line that can divide two objects into exactly the same shape. Well, if an animal has radial body symmetry, that means it has many axes of symmetry. Usually the animal is circular, round, yes. The circle has many axes of symmetry, right? It's like I have a circle here. Huh, why is
10:06 the circle ugly? Now. A circle has many axes of symmetry, right, dear? If you want to cut it straight, it will still be in two equal pieces. Cut it, cut it sideways, it remains in half. The shape is more or less the same. Cut diagonally into two. The shape is the same. Cut diagonally into two. So, radial body symmetry is usually found in animals that are round in shape. K my friend is round. Does that mean the body symmetry is radial? Eh, it 's not like that, dear. No body shaming. No body shaming. Yes dear. Well, animals that have radial body symmetry, remember radial means having many axes of
10:51 symmetry. Many axes. Ah, the writing is bad. Axis of symmetry. Well, animals with radial body symmetry are usually dioblastic. L. What is dioblastic, Brother? We usually see this diploblastic in the embryonic phase, honey. This diploblastic is actually the nature of the embryo, dear. Yes. What does it mean to have a dioblastic embryo? This means that the embryo has two layers of tissue. Yes. So, dioblastic is actually the nature of the embryo, dear. Animals when they are still embryos. Come on, who here still remembers when they were still embryos? Come on, who is it? There isn't any. L is
11:39 fine. I, I, I'm tired. It's not clear, huh? Well, the embryo in animals has layers of tissue. There are embryos that only have two layers of tissue. There is an outer layer, there is an inner layer. Well, the outer layer is called the ectoderm. The layer in its name is endoderm. Yes. So if an embryo has two layers of tissue, that layer is called the outer layer. It is the ectoderm. The inner layer is called endoderm. Ecto means outside, endo means inside. If an animal's embryo
12:26 only has two layers of tissue, it is called diboblastic. Well, usually those with radial body symmetry are also diploblastic. That's why I combined this into one. Radial body symmetry in ploblastic. For example, there are groups of kenidaria and stenophorora. Who is the Kenidaria group? There are jellyfish. Don't use catfish. Catfish are in different groups. The jellyfish is a kenidaria. Then there's the hydra. There is an animal called hydra which is also a kenidaria. There are more sea anemones. Sea anemones are also kenidaria, right? Sea anemones are the homes of fish. Uh, coral reefs in tropical waters. Well, that's dear Kidaria. Nemo's house. That's right. In Finding
13:13 Nemo, yes. Someone commented on Aurelia Aurita. Yes, that is the scientific name of one species of jellyfish. Funny huh. Who here wants to name their daughter Aurelia Aurita? I'll make fun of you. Jellyfish jellyfish . Jellyfish [Laughs] yeah. What else can Aurelia Aurita's name be? Aurel is just sulking. Well, if it's stenophora, stenovora is also a group of jellyfish, friends. But if stenovora is a jellyfish that we call comb jelly. The problem is that around the skin there are
13:58 lots of fine hairs like a comb. There. So, why do I call them kenidaria and stenophora? Because if you pay attention to kenidaria and stenophora, kenidaria and stenophora were previously one group but now they have been divided into two. Previously they were called suelen terata. suelenterata. Well, that's why there is no term swelenterata on this slide. Because now swelenterata is separated into two, there are kenidaria and also stenophorora. These are animals whose body symmetry is radial and diploblastic. Well, but for us, we humans, we only have one axis of symmetry, right? It's impossible for us to have many axes of symmetry. No matter where we are divided, the
14:44 shape will still be the same, right? So, for example, we draw a person. Well, for example, if we draw a person, sorry. Oh, the picture of the person is really handsome, sis. I know. The axis of symmetry of a human is only one, right in the middle. So there's only one from head to toe, just one. There's no axis of symmetry anymore, right? There are no more imaginary lines that can divide our bodies into the same shape. It's really ugly, Sis. Yeah, sorry. If the drawing is good, I won't be a tutor, I'll be a painter. Who here wants a painter? Hugged and rubbed. Oh, oh, I'm scared. Afraid.
15:33 Revisika is ugly [Laughs] the picture. Oh my God. I'm sorry. Wrong. It's my fault that we always get night classes. The more natural people are, the stranger they become, the more unpredictable, the more chaotic they become. Hawi wants to? Do you want to? Hawim wants to. O. Want to go during rush hour, Sis? That's right. If not prone to going crazy, prone to being sleepy. Well, we only have one axis of symmetry , which is a shame. We only have one axis of symmetry. That's why we are said to have bilateral body symmetry. When a nuclear bomb is detonated. No mistake, it's a bilateral dangdut song.
16:20 Yes, who else has bilateral body symmetry ? There are birds, there are worms, unfortunately the microphone is turned off. Hmm. Who is it? W is there. Wow wow wow wow wow it's muted huh. Wow wow wow yeah. Hmm. Pigs are not included, like pigs, they only have one body symmetry . There's only one line that can divide his body into two identical shapes . Am I included, Sis? Yes, you can. Goats are allowed. Oh, it's called everything, hedgehogs are allowed, dragonflies are allowed, butterflies are allowed. It only has one body symmetry. That's why we call it bilateral. Bilateral animals usually have embryos with three
17:06 layers of tissue. That's why here I wrote bilateral and triploastic. If di di means two. Tri tri means three, right? So a triplastic embryo has three layers of tissue. The embryo has three layers of tissue, namely the ectoderm layer. Then there is the same layer as the ectoderm, which is the outer layer. The inner layer is called endoderm. Well, the middle layer is called the mesoderm. So that's the difference between a diploblastic embryo and a triploblastic embryo. If it is diploblastic, there are only two layers of tissue, outer
17:54 and inner, the endoderm and endoderm. If there are three layers of tissue, it means that it has an outer layer of ectoderm, a middle layer of mesoderm, and an inner layer of endoderm. Usually those who have three layers of embryonic tissue are said to have bilateral body symmetry. So usually radial is diploblastic, usually bilateral is triploblastic. It's nice to remember, isn't it? Well, then read it to the left again. Eh, I read it to the left, sorry, it's wrong. Read it to the right again, honey. Animals whose body symmetry is bilateral triploblastic are included in a group called bilateria. Well, the bilaterian group is
18:40 divided into three. Well, based on the existence of the coelomic cavity, yes. So the cavity in the embryo is called the coelomic cavity. It says S E L O M. Coelomic cavity. The coelomic cavity is a cavity formed from the mesoderm. Wow, remember that the coelom cavity is a cavity formed from the mesoderm. A cavity within the embryo formed from the mesoderm. But there are bilaterian animals that do not have a coelom cavity. Who's that? Well, animals from the coelomate group. In biology A that means no. So, acoelomates do not have a
19:26 coelom. So, who is included in the acoelomate group? Acoelomate, not acelole. Watch out guys. Oh, the terror. Suddenly what group? Aselole group. Not acoelomate, yes. Those included in the acoelomate group are flatworms. If you find worms, they will be flat and thin. Well, that's a flatworm, honey. The group of flatworms is called Helminths. This is a group of flatworms. Well, then there are those who have a coelomic cavity but the coelomic cavity is fake. Darling, I have a false coelom. Well, the
20:13 false coelom cavity or pseudo coelom cavity. So, as I said earlier, the coelom cavity is made of mesoderm, from the embryonic layer in the middle. But there are also coelomic cavities that are not 100% formed from mesoderm. he even he even is composed of endoderm as well. Well, that's a false coelom cavity, not 100% genuine mesoderm. False coelomic cavity. In biology, fake is called pseudo. So if your love is fake it means pseudo love. Because if the coelomic cavity is false, the term is pseudoelomata. Who has the? Ah, who has a fake coelom cavity ? There are worms called
20:59 nematodes. Well, nematode worms or in Indonesian they are called gilik worms. So if you find a worm but its skin is smooth, there are no segments, there are no pieces of skin, meaning there are no joints. Well, that means internal worms from the nematode group. Because earthworms have segments, right? If we draw an earthworm, for example, this is the body of the worm. Well, its body looks like it has segments, right? Well, that's not a nematode. But if you find a worm but its skin is smooth, very soft, well that's a nematode. The image is very abstract. The important thing is that you understand that it's a worm, my dear. Hehe. Use
21:46 your imagination. So, okay, acoelomates done, pseudoelomates done. Well, those that have a true coelomic cavity are grouped into the coelomate group. This area contains the remaining groups of animals whose names have not been mentioned yet. Yes, we mentioned porifera earlier, remember that porifera are parazoa, they do not have true body tissue. The rest of the others have everything. Then we have already mentioned cnidaria and stenophora . They are radially symmetrical and diploastic. Then we move on to bilateral and triploblastic. It is a bilaterian group. We already mentioned that Coach Helmintes
22:31 doesn't have a coelom cavity. We have already mentioned that nematodes have a coelomic cavity, but it is a pseudo coelomic cavity. Well, if they have a true coelom cavity, that means the remaining animal groups are a shame, right? There are annelids, a group of earthworms, there are mollusks, a group of animals with soft bodies, mushy like me. Then there are arthropods. Arthropods are jointed animals. Even his legs are jointed. The whole body is segmented. Then there are echinoderms. Well, this is Patrick's group. starfish in the blue sea yeah. Then there is the chordate group. Chordata is a group that also contains animals with backbones, aka
23:19 vertebrates. Hmm. Vertebrates and some other animals make up the phylum chordata. Well, starting from annelids to chordates, they have a coelomic cavity. Nice. Yes, based on the coelomic cavity, bilaterian animals are divided into three. There are acoelomates, pseudoelomates, coelomates, but there are still other body cavities besides the coelomic cavity. These coelomates are only distinguished by the presence of the coelomic cavity . Well, then based on the development of the embryo. Well, the embryo in the animal usually forms a hole first. We call it an opening. In the language of
24:05 books, it's not. What is the opening? Yes, literally a hole outside the body. Well, some of the holes develop into mouths, some develop into anuses. Well, the animals whose embryonic holes, the embryonic holes that are first formed and develop into mouths, are animals from the protostomata group. Hmm, proto means the previous one, the first one. Stoma means mouth. Well, that's why in animals from the protostomata group, if the embryo forms a hole or a cavity, the hole will later develop into a mouth. So in protostomata animals,
24:50 the mouth developed first [Music] . Who used to be included in the protostomata group? Starting from helminth platych, nematodes, annelids, molluscs, arthropods, stop. Hmm. Since the remaining two are deuterostomes, deuterostomes are the same, right? Deuterostomata, deuterostomia are the same thing. Deuterostomia means that the embryo forms a hole first and that hole will develop into the anus. the place where the remains of the hellish food that you swallowed in this world come out. So in deuterostomes the anus develops first,
25:38 then the mouth. Well, there are only two members of the deuterostomia . So it's good to remember that there are only two deuterostomes, echinoderms and chordates. Hmm, cordata means including vertebrates. vertebrates means including mammals. Wow, it turns out that when we were embryos, the first thing that formed in our bodies was the anus. Yeah. So you guys have had times when you were nothing more than a hole in your anus. Astagfirullahalazim. Well, what can I do, honey? Our embryo develops a hole. The hole develops into an anus. The mouth develops later.
26:25 Yes, how is it? There was a time when we were just embryos with an anus hole, nothing more and nothing less, we were just like that, right? [Music] Heeh. Funny huh. We're like echinoderms . The anus develops first, then the mouth. So it's a shame that the dirty ones are the ones who develop first. Huh huh. There's more time than words today, huh? It is okay. If that reminds you that we are deuterostome animals, then that's fine. Bro, where did you miss these last two divisions ? From the development of the embryo, dear. In protostomata embryos, the mouth develops
27:12 first, then the anus. But in deuterostomy, it's the opposite, the anus develops first, then the mouth. Okay, that's more or less the review for Animalia. No need for too many. In essence, this is the basic concept of grouping mammals, my friends . So eh mammals are animals. So first he was grouped based on his body tissue. There are parazoa. Wrong wait a minute. First we group them based on their body tissues. There are tissues, some do not have true body tissues (parazoa), some have true body tissues ( eumetazoa). Eumetazoa was later divided again. There are those whose body symmetry is radial and whose embryos are diproblastic. This means that the
27:58 embryo has only two layers of tissue , the hectoderm and the endoderm. There are those whose bodies are bilaterally symmetrical. So it only has one axis of symmetry. And usually if the embryo is bilateral, it is triploblastic. This means it has three layers of tissue. There is ectoderm, mesoderm, and endoderm. But if you pay attention, here I give a bilateral asterisk except for echinoderms. Ekkinoderms are included in the bilateria group, but they have many axes of symmetry. Is not it? If we think about it, starfish have many axes of symmetry . Not just one, right? We can split the starfish
28:44 anywhere and it will produce two pieces of the same size. Well, that's why I put an asterisk here. So, echinoderms actually have radial body symmetry, but echinoderms are triploblastic, so they are still included in bilateria, not thrown away, not grouped with jellyfish, no. So, animals from the bilateria group are divided into three based on their coelomic cavity. Some do not have acoelomates, some have a coelomic cavity but it is false, pseudoelomates. or just a fake, your cell cavity. Some have true coelomic cavities or coelomates. Well, bilaterians are also divided into two based on the development of their
29:32 embryos. Did the mouth or the anus develop first? If the mouth develops first, it is called protostomata. Proto came first. Stomata. Stoma means mouth. If the anus develops first and then the mouth, well that's called deuterostomia. Deutero means later. Stomia comes from the word stoma which means mouth. So the mouth comes later, the anus comes first. Oh, there are only two deuterostomia films, unfortunately. Echinoderms and chordates. Ah, that's enough for the preview. That is the basic concept of animal grouping, yes. God willing, this material will be
30:18 very useful. Because usually UMUGM usually asks about true body tissue , dioblastic or triploblastic body symmetry , and whether it is coelomate or pseudocoelomate. Well, usually he asks the same questions, right? Although there may be other questions too . Yeah, no problem. Are my friends ready for this world? Are my friends ready for this world? I've taken a screenshot of this. Ready to be dribbled. Gojek UGM. Anang ning nongeng nongipak bang dung dingser. Okay, let's get to the first question, dear.
31:04 Porifera. In porifera, oxygen binding and CO2 release are carried out by choans which are directly adjacent to the spongosol cavity. Because porifera enter water through the ostium and then enter the pongosol cavity. Is this the answer? Not on the previous slide. Come on, please just answer it first. The important thing is that you know that porifera are sponge animals. An example of this is Spongebob. Hmm. What is Koanos , Sis? What is Ronggas Pongosol, Sis? What is Ostium, Sis? Okay. Okay. We'll give you some directions, okay?
31:51 We'll give you some directions, okay? We will give you instructions for working on this question. Porifera let's say this is my picture of a porifera animal. Sorry again if the picture is bad. Sorry if the picture is bad. I'm not a painter. Well, in the middle of the body of the porifera, inside the body of the porifera there is actually a very large cavity. So, gosh the picture looks like a lantern. I'm sorry , honey. I'm sorry, honey. Inside the body of the porifera there is a large cavity. So the inside of the body is
32:38 hollow, honey. like tofu but there is no hollow inside. Well, the large cavity inside the body of the porifera is called spongosol. Spongosol yes. So, this large cavity is called spongosol. It's written as sponge coel but don't read it as spongeocoel. Oh, that's so ugly. Spongebob. Coal coal. Coal coal. Eh, that's not allowed. This is another species. Please respect it. Well, the writing is sponge. You already know there is something called spongosol. Then porifera are animals that have pores, right? The pores or holes on the surface of the body are called osti, well,
33:24 I've told you about that again. So the pores that are all over the skin are called ostum. Her mouth, her mouth yeah. The mouth that comes out of this spongesol, huh? This is the big mouth at the top. This is called the osculum. Well, I've told you, Porifera has given too many instructions. Spongosol has been told what it is. Ostium has been told what it is. Osculum has also been informed. What choanocytes? Choanocytes are a type of cell found in sponges, honey. Come on, some people say A. A yes K is good
34:09 A. A I think A B. Okay, some people give different answers. B. You guys usually answer A when you don't know the answer. The main thing is that the statement is correct, the reason is correct, and there is a cause and effect relationship. Ouch. Ouch. What does it mean? What does it mean? D. Okay, someone answered D. Okay, okay, okay. Here you go. Let 's discuss the bottom one first. Let's discuss the bottom one first. Let's discuss the bottom one first. Porifera enter water through the ostium then the water enters the spongosol cavity. The answer below is correct. Yes, so
34:55 all of these water porifera live in water, dear. Some are in sea water, some are in fresh water. So there are some in the lake, some in the river. That's right. Porifera take water into their bodies through the ostium pores. Later the water enters the pongosol cavity. Later the water comes out through a hole that we call the osculum. So the one below is correct. But the top one. Well, the one above, the one above, dear. Be careful up there . Choanocytes. Choanocytes are cells in porifera. Is it true that koans directly border the spongosol cavity? So, the body of a porifera only has two layers of cells. There is an outer layer, there is an inner layer.
35:42 So, if we use my really handsome picture, it's like Leonardo da Vinci's picture. The outer layer of the porifera means that it faces the surrounding water, right? The outer layer of the porifera means the layer that faces the water around it. It's like his skin. Like his skin. Well, that layer is called the epidermis. The epidermis of porifera is composed of cells called tinaocytes. Earlier in the chat, someone answered correctly, pinacocytes, meaning someone said correctly that there are cells called pinacocytes, right? Then there is a layer of cells on the
36:31 inside that coats the spongosol, so there are cells on the edges of the spongosol, right? So on the edges of the spongosol in the inner part of the body of the porifera, there are cells called jeng jeng jeng jeng koanocytes. Now, are the koanocytes panicking yet? Are you panicking yet? So the top, back and back of the koan are right, they are directly adjacent to the pongosol cavity. So far so good. Yes, it's still okay. But the front is darling. In porifera, oxygen binding and CO2 release. We know that animals need oxygen. The animal releases CO2. This is what
37:17 we call breathing, yes. This is what we call breathing. Porifera can breathe throughout their bodies. So, pinacocytes can bind oxygen and CO2, choanocytes can , all of them can. So not only can the koan's entire body directly take oxygen from the water and release CO2 from the water. So I apologize for the answer. Wrong answer. So the correct one is D. [Laughs]
38:04 Oh, it's a joke, UGM nang ning nang nang ning nung pakip bang [Laughs] dungding sor, no joke, okay, okay, okay, so if the statement above sounds like the only thing that can take in O2 and release CO2 is koan, even though it doesn't matter that all the cells in the porifera's body have only two layers. you can do that. That's right. Porifera can breathe in all parts of their body as long as they are exposed to water. So it can exchange oxygen and CO2 with water. Eh, why is that, Sis? Yes, because the body of a porifera only has two layers, unfortunately. Thin. So, oxygen can go
38:50 straight in, CO2 can go straight out. Ugh. Yes, dear, yes. Yes, dear. Hehe. So, Sis, why can't we do it like that? Hey, your bodies are thick. Are there only two layers of cells? It's also difficult to get oxygen in, it can't be done. But what is the function of the koan? Okay, nice question. So here it is, honey. So it's like this, honey. The food is porifera. How do porifera eat? Porifera or sponge animals, right? Spongebob. Porifera eat by filtering water, dear. So the food particles in the water are filtered. So it's like saying, when you eat, you have to
39:35 drink water first. The water is filtered to remove the small food particles that you eat. Yum yum yum yum yum. Well, that's how porifera eat . Isn't eating kby paty in cartoons, honey? Eating kby paty is in cartoons, right? But in their natural habitat, Porifera actually filter water to get small food in the water. How do polyfera filter water? Yes, I said earlier that water enters through the ostium, then water enters the spongocoel cavity, then water exits through the osculum. So when water enters the spongosol, who filters food from the water? Choanocytes. Yes, so the function of these koan cells
40:22 is actually to eat or more precisely in brackets to filter food from water. Filtering food from water. That is the koan's job. Why? Because the choanocytes are in the spongosol walls. The water is collected in the spongosol and enters through pores called ostia. But later it will be collected in the middle, which is called the spongosol cavity. Well, the choanocytes that are on the edges of the spongocoel filter food from the water, scooping up the water. Oh, I'm hungry. Is there any food? Hmm. Someone else commented, "Brother Bagus used to be a porifera, guys. Who cares?"
41:09 Hehe. The oculum is the mouth, but its role is like the anus, right? Yes The osculum is more like an anus. Because the water comes out through the osculum . Okay, I'll screenshot this first, otherwise I'll get angry if I don't screenshot it. Ah, but the picture is really beautiful like this, right? But still, Sis, screenshot Sis, screenshot. Yeah. Are you ready for the next question, honey? Hmm. Let's shake his mind again with the next questions, okay? Let's move on to question number two. Dribbled. Gocek UGM. Oh, there's a better picture. But yeah, my picture is enough. Number two. Come on. Ugh. The
41:57 easy part of biology. I smiled to myself. Multicellular organisms with true tissues. bilateral symmetry triploblastic acoelomate, acelole. Happy, joyful and happy always. Here I teach you to teach plantai and animalia. Oh my, even though it was already on the first slide, there are still many who got it wrong, Cinta. This is the answer, all of A, B, C, D are all there. Be careful if you answer E. Protozoa. Eh, protozoa are not animals. Protozoa are protists. Just be careful if you answer E. There's another person who answered E. Oh God,
42:43 please repent, it's a shame. Hehe. Sis, my legs are cramping because of your excitement. Well, it's your own fault. I'll just stay quiet here, okay? It's just your legs that are shaking. I'll answer it later, Sis. Dear Allah. Okay then, UGM will accept you. Astagfirullahalazim. [Laughs] Oh, it's a shame someone still answered D. Heh, read it because their eyes are open. True network. Porifera do not have true tissue. What we discussed earlier is that the tissue of porifera is not true tissue. Someone answered D. Wrong. Oh, this is so easy, honey. the
43:29 key word of which is acoelomate, does not have a coelomic cavity. The only ones who do not have a coelomic cavity from the remaining answers are helminth trainers. Yes, that's right darlings. The answer is ah hooray, always cheerful and happy. Here I teach you. We learn biology in a fun way. Here I teach you to have fun. Yes, it's really exciting. There are already words such as asela, helminth trainer, flatworm. Yes, it is flat, there is no coelom cavity. Hoba is really easy, huh? It's really easy,
44:16 right? Oh, biology is easy. Greetings UGM. Yes, I don't need to screenshot this . The scribbles are just like this. No additional information. Yes, let's just continue, okay, honey. Are you ready for the next question? Here's number three. Here I teach you to be happy and happy always. Here I teach you. What causes beef liver fluke ? Shut up. Siifa Zaahra in the chat column. Shut up. This is beef liver fluke. Oh, if only my heart was [Laughs]
45:02 you. Sis, be quiet first. Su. Okay, he told me to be quiet, he said. Okay, let's continue, okay? We want to eat the bananas that we haven't eaten yet with [Music] finished. Mmm. Hmm. [Music] Hm. Sis, I want to say something to ShrN Nabila. Similar, Sis. Eh, who does it look like? Please explain who you resemble. Who does it look like? say it if you
45:55 dare. A banana is not tasty, please. Good grief. Bananas are actually the best source of sugar , right? So, if you are hungry, but want to get lots of energy, bananas are the rescue. That's why there are actually quite a lot of athletes who eat bananas during their breaks. Because the glucose content is quite good for your energy to study, dear. A b a b d a c d a d. Let me tell you, honey. Beef liver flukes are flat in shape. From there, the answer is already visible. Impossible.
46:44 The answer is no, it can't be nematodes. Because of beef liver flukes, worms that are in the beef liver, worms that are dangerous if we eat them, they can also infect our liver and your liver. Oh my, there are worms in your heart . Oh, in my heart you are not a worm. Oh, God forbid. God forbid. God forbid. Beef liver fluke or hepatic fascia is a Helminth trainer. But what class is Helmintes' coach? Which group? The answer is A. Trematoda. Okay. Be happy and happy always here. Oh my, is this actually already in Mas Mono's slides about Animalia? The
47:30 Helmintes coaches were divided into three groups. There are three groups of flat worms, right? There are trematodes, there are sestodes, there are turbellaria. Well, these are the pictures on the next slide. Wait, tech. Well, that's it dear. That's me, yeah. Coach Helmintas only has three groups under him. There is a class of turbellaria. Turbellaria. Well, turbellaria is a worm that you may have heard of often. Pelararia worms. A worm that if cut in half can make a new head and tail. Our friends, flat worms. Well, this Turbellaria group usually lives freely, it is not a parasite. So, yeah,
48:15 he just lives alone. Turbellaria, for example planaria worms. The scientific name for the planaria worm is dugesia. Then trematodes. For example, trematodes are flatworms that are parasites in the livers of animals. The parasite in the animal's liver is called liver fluke. And there are also things called blood worms, dear. Bloodworms live in your intestines and can actually suck your blood. Oh, how scary. Well, that's the trematoda class. Then if it's the sestoda class, this sestoda class is easily infected with tapeworms. If you find a worm that is flat and really like a ribbon, checkered like this,
49:01 its body is checkered like a ribbon. Well, that must be from the test class. For example, this tapeworm. This is called the taenia tapeworm. Its name is taenia tapeworm. There are two Taenia tapeworms, my friends. There is taenia solium, there is taenia saginata. Well, taenia solium is usually found in pig intestines. So, for example, if someone eats pork that is not clean, it will contain parasites, namely taenea solium, one of them. But if tainia saginata is usually found in cows. So, be careful when eating beef that is not clean or beef that is infected or undercooked, as it could contain
49:47 Taenia sagata germs. Well, that 's the helmint test trainer from the test class. Why can helmet trainers test based on physical condition? That's right. Helmintes' coach's body is all flat. If you look at the picture, his body is all flat, it's a shame. Really flat. If you hold it, it's really thin. So, that's why it's called the flatworm test helmet trainer . That's the scary thing. I'm getting goosebumps, Sis. Worms. Soon the sacrifice will be afraid. Don't be afraid if the animal you eat is free from parasites, it's safe, just relax. So, before eating, make sure to wash your hands. Don't be careless and
50:34 eat straight away after digging up the dirt in front of your house. Yes, how could it not contain parasites? Yeah, no? Oh, yeah. Then, when cooking meat, make sure it is cooked thoroughly so that the parasites die. Because if it is not cooked properly, there are many risks, right? It's a shame. Usually when it comes to steak, people like to eat steak that is still a bit raw inside, still a bit red. If the meat is clean, it's not a problem, but if the meat contains parasites, gosh, that's scary, I'm afraid. Oh yeah. Okay, that's coach Helmintes, yes, dear. There are three groups, turbellaria, trematoda, and sestoda. Moving on, to question number 4AT next. Be happy and happy
51:21 always. Animals with soft-bodied, multicellular, and triploblastic characteristics. The body is bilaterally symmetrical and asexual. Having a clear head with special head receptor organs . These are the characteristics of animals that are included in the group. Alah, the keyword is already in the question. The keyword is very clear in the question. The answer is definitely that one. Ah, I mentioned earlier that someone answered E C. Always be happy and cheerful. Aselle. Eh, no, acelole.
52:06 Acoelomate. Wow, what a great coach Helmes is . Someone answered E. We've been thinking about this just because we're the Helmintas coach. The answer is E again, E again, E again. Oh, oh dear. Tsk, how could it be that easy? Oh, I'm challenging you. Someone answered D. C. Hm. Hmm. B. This is different again. This is different, B. Oh, dear. Dear dear. Let me tell you this , honey. It's triploblastic, dear. Triploblastic porifera is impossible. So lanterns are also impossible, right? Soelenterata
52:51 are kenidaria and stenovora. Coelenterata are diploblastic. Oh my God. I'll pinch the kidneys one by one . The answer is very clear, dear. There are soft-bodied words. Oh, animals with soft, mushy bodies, right? Keep a clear head. Having a clear head and having organs in its head for sensing it is definitely a mollusk. Oh, be happy and happy always here I teach you. A is very easy, yes. Oh dear, the answer is C.
53:41 Arifa's words are already in the chat column. Bro, shut up. Yep, today the song isn't insulting because it's not offensive. Later, if I check again, I will insult you. Oh my, my God. Tsk, sorry typo. Oh no, ... I don't accept Taipo's answer. Anyway, the answer is C. Molluscs ? Soft-bodied animals. Ouch. Why not E? Okay. Why not the Helmintes coach? Because these words have a clear head. Coach Helmintes did have a head from the pictures I showed you earlier. The head and tail
54:27 sometimes have the same shape, honey. Yes, it would be scary if coach Helmintas had a bald head. Oh, don't make, don't make, horror animals, it's a shame. Don't make scary animals. No, don't make ee animals that are in horror movies. Don't create monsters. Yes, it's scary, isn't it? Coach Helmintas doesn't have a head, what a shame. Oh my, that's scary. Those who are flat are said to have clear heads. Oh my, that's so scary. I'm afraid of anomalies, huh? Okay, ready to be shaken again. Dribbled. Check UGM. Nang ning nong nang ning
55:13 nong. Thank you, Mr. Dundingser. Let's continue, okay? Question number five, yes, dear. Ouch. These green mussels are usually sold by street vendors with Padang sauce. Uh green mussels boiled in Padang sauce. Oh, that's delicious. The green mussel mitilus edulis is a member of the lamelli branchiata class. Because the green mussel Mitilus edulis has the characteristic multi-layered gills. What is the answer? Yes, what we know is that shellfish are definitely molluscs. The clams are classified as molluscs because their bodies are soft. Come on, is that mollusk shell a film,
56:01 right? Under film, there is something called class. So, do mussels belong to the lamelli branchiata class? Do green mussels have multi-layered gills? Oh, I already gave you a hint. Clams are mollusks. Clams are mollusks. Molluscs. It was already on Mas Mono's slide yesterday. Just read it. Mauluska contains all kinds of classes there. Oh, some answered A, some answered B, C, D. Here, someone said D. Oh, how come it's so easy? Hirono Hirono . Let's see . Hirono said, "D, how come it's
56:47 so easy?" Oh, challenging, challenging. Akak, sorry if that's true. Hey, he's more arrogant than Pharaoh. He was more arrogant than Pharaoh, the king of Egypt. Oh my God. A D A D, Sis, there aren't any difficult questions like that. This is too easy. Okay, let's talk about molluscs first, honey. The molluscs consist of five groups. Molluscs are divided into five classes. Yes, here we are studying the classes of mollusks. The first is the polyplacophora class. There is a class called pollinatorvora. If you meet this animal, this animal is
57:33 usually the one pictured on the far left, the animal pictured on the far left, the animal pictured on the far left is him, his brown shell is very hard. Then, it usually sticks to the rocks on the coast and sticks really tightly. The animal pictured on the far left is called a chiton. Well, this chiton animal is a mollusk, my friends. And he's got a shell. If you count the shells, there must be eight plates. 1 2 3 [Music] 4 4 5 6 7 8. Well, the shell has eight plates. These are the typical characteristics of the polyplacopora class. Pollaforvora's
58:21 shell has plates. Then the second class of molluscs, this is easy, right? The second class of molluscs includes snails, slugs, and sea slugs . Maybe you have seen on TV a sea snail without a shell. Well, that falls into this class because they walk on their bellies. The scientific name for the stomach is gaster. The scientific term for legs for walking is podos. So the name of this group is gastropoda. They walk on their stomachs. Gaster means stomach, podos means foot. So gastropods are animals that walk on their stomachs, right? These are examples of snails , sea snails. These are the animals
59:06 that crawl, you know, they walk using their stomachs, leaving mucus everywhere. This is the gastropod class, dear. Well, the third one is class. Hmm, this class has a lot of other names. We can call it bivalvia because it has two shells. Bivalvia because it has two shells. Gary is included in gastropods means. That's right. Gary is Spongebob's pet gastropod . Bivalves are called bivalves because they have two shells. There are two shells and they can open and close like your mouth. The shells are in pairs or groups, also called pelesipods. Pelesi means axe.
59:53 So the legs are shaped like axes. If you have ever seen the legs of a clam, they are shaped like an axe, like a knife. So it's so thin. If you have ever seen clams in YouTube videos or maybe on TV, on TV programs, sometimes there are clams whose meat comes out a little bit and then they drag their bodies in the sand, those are their feet, honey. his legs are shaped like knives. This is because the clam has a foot that is shaped like a knife, that's why it is called a pelesipod. Pelesi means axe, podos means foot. Or another name is lameli braniata. Oh, the branchial lamelli are
1:00:40 because their gills are multi-layered. Hmm. So, so if we go back to if we go back to the previous slide, green mussels are members of the lamelli braniata class. That's right. Because green mussels have two shells. Green mussels. Why did he enter the branchial chlamydia? Because the gills are multi-layered. That's right. top and bottom are correct and interconnected. The answer is AOR. Here I am to cheer you on, rejoice and sway with you, Aselle. Here I am to entertain you. Oh, it would be
1:01:30 fun if I wasn't so stupid, huh? Oh, Hirono laughed, Sis. Hirono did it twice, you know. D. Nothing is more difficult than D, Sis. The difficult ones are a bit more difficult. Wrong gocek gocek UGM nang ning nung nang ning nong Pak Gulip Hirono, the answer is wrong. Hirono challenges UGM. Hero. Wow, there's someone chatting here. I'm always right. Oh, amen. I hope you always have the right spirit at UMUGM, my darling.
1:02:17 Amen. It's okay Hirono. I am with you. Just leave it alone, Brother Bagus. That's how it is . Oh okay. Okay. No problem. No problem. Just because you're not on my side doesn't mean you're not safe, you're not immune from being dribbled . You guys are on my other side too. You there, I'm across from you. Anjay. I will still keep on groping . Oh, honey. If you noticed earlier, I said that Molluscs have five classes. I just mentioned three, honey. Eh, no one is paying attention, right? There are only three molluscs that I mentioned earlier
1:03:04 . Polyplacophora, gastropoda, and bivalves. Two more to go, honey. Hey, here are two more. Here are two more. Yes, here are two more. Well, someone asked what class Squidward is in, Sis? Squidward is in the Sevalopoda, honey. Sevalopoda from the word Seval. Seval means head. Podos means feet. So, feet on head, head on feet. Well, that's a Sevalopoda, right? That song is actually about cephalopods. Sevalopods are molluscs whose feet are on their heads. Hmm. There are squid, there are cuttlefish, there are octopus. Then if
1:03:51 you guys, maybe you know there are Sevalopoda that have shells. So there is a squid friend but it has a shell on the outside called Nautilus. This one at the bottom is a picture of a Nautilus. Sis, I'm getting hungry. Yes, same. I also want to try squid with Padang sauce, it's really delicious, isn't it? Sweet and sour squid. Ah, so delicious. Oh, I want to. If the feet are on the head, it means he moves using his head, Sis. Yes, use your feet, honey. Yes, use your feet only your feet on your head. Well, the legs are what we call tentacles, right? Well, Squidboard falls into this class, honey. Nautilus is not a prehistoric animal
1:04:37 that is already extinct. Where there is Nautilus still in this world, my dear. It's just that he hasn't changed since before. So, from hundreds of millions of years ago, it hasn't changed much, that's why it's called a living fossil . Where do the shrimp go? Shrimp are from a different group, my dear. Shrimp is a different film. Shrimp are arthropods . Yes, shrimp are arthropods, not molluscs. Well, then there are more shells but they don't have two shells like this. Not shellfish but conical shells like the one in the picture on the right, the name is the class scavfopoda. Well, the scaphopod class is shellfish, but shellfish with conical shells. So it's not a shellfish with
1:05:23 two shells like green mussels, blood mussels, or even shellfish like that. Pearl oyster. Well, there are two shells, right? Now this one is not like that, its shell is shaped like a trumpet. Well, this falls into the scavopod class . Okay, those are the five classes of molluscs , honey. Wow, we learned a lot today, huh? We study animals. So, that's why one of the tips for learning about animalia is that when you eat, you should remember which group it belongs to. Eat chicken. Oh, chickens are birds, right, aves. Well, keep eating the squid. Squid in
1:06:09 Padang sauce. Oh, it's a sevalopod. Sevalopods enter molluscs or eat shellfish. Hmm. In Valvia. Nah, I only eat chicken, Sis. Okay, chicken means Aes, because birds are vertebrates. Oh, I want squid, Sis. Yes, buy it yourself, it's a shame. I also want to. If I had thought about it first, the cat would have taken the food before it was finished. Sis, I eat bean sprouts, Sis. Yes, that means pelante, dear. Different kingdoms. Let's continue. Question number 6. Well, the following characteristics are possessed by bees, namely bees. Hmm. Bee. What group do bees belong to? Oh, bees
1:06:56 are insects. Hmm. Who here dreams of being an insect? I. Bees are a group of insects, right? Insects are included in the arthropod group. Ah, I've given you a hint . Arthropods. Well, the characteristics possessed by arthropods are yes, that means they are possessed by insects. But this is the bee's property. What is it? What are the characteristics of bees? Some answered C, some answered E, some answered A, some answered C. Ka e. Wow, not sure this is the answer. E, E. Four is correct. E, E C A B C E E E A C E A C E C A E. Wow,
1:07:45 hero no hero no. Yes, with arrogance equal to Pharaoh, king of Egypt. Eh, this is easy . Let's see, Hirono . Watch out, Hirono. Wow. B A E no debate. D E E or C E D B. Oh, let's get ready, let's sing, gocek gocek UGM. Nang ning nung nang ning nung pagipat bang dung dings bee dear bee. Remember arthropods. The arthropods must be triploblastic. Number one is definitely true. Because the only diploblastic groups are jellyfish, namely kenidaria and stenovora
1:08:32 or swelenterata. Arthropods are triploblastic so one must be correct. The answer is D. Hmm. I said I would repent. What did Hirono answer just now ? Let's check. Oh, Hirono answered E. Okay, two wrong. Hehehehehehe. Here it is, my friends. Bees are insects, right? The insect has the ability of metamorphosis. Wow, it can change, yes, from the stages of life it can change, it can experience metamorphosis. But there are two types of insect metamorphosis, right? Metamorphosis. Ouch. Metamorphosis.
1:09:20 There are two types of insect metamorphosis, right? There is holo metabolism, holometabola and there is hemi metabolism metamorphosis. Hemi metabolism. Sorry, this text doesn't fit so I wrote hemabola below. The writing should be connected, right? Well, metamorphosis holo holo metabola. This holo metabola is a perfect metamorphosis. This means that young animals and adult animals are very different. Wow, how come your glow up is so good? When you were young, you weren't like a fat, ugly, and sluggish person. Fat, ugly caterpillars
1:10:06 crawl on the leaves. Ugh. But when you grow up, wow. become a very beautiful butterfly. Well, that's it. So if the glow up turns out that the glow up turns out that wow it makes people forget, makes people not realize, gosh, it's so different from when I was little. Well that's holo metabolism. An example is a butterfly, dear. Eggs, caterpillars, butterfly cocoons. Poor you. Well, that's how it is . It's a holo metabola. Yes, the metamorphosis is perfect. So, young animals and adult animals are very different, making people forget. Wow, it really does glow up. Wow. Well, if hemi
1:10:54 hemabola hemabola is an incomplete metamorphosis. It means a metamorphosis that people don't forget. So if it's hemi, well, the writing is really bad. If the hemabola is between young animals and adult animals, the shape is the same, only the size is different, only bigger . Yes, so if the hemobolet doesn't glow up, it's just getting bigger . Well, bees. Is that bee a holo or a hemi? Come on. Is the metamorphosis of bees holo or hemi? Someone answered hemi. Someone answered holo.
1:11:40 Darling. Darling. Is the bee a holo or something? Seriously, someone answered holo . Is it really a holo bee? Have you ever seen a young bee? Huh? That's the shape of a bee from birth. Are there really caterpillars that will hatch, Sis? Asked hemi or holo? Hoba. Oh, when a bee egg hatches, it will already be a bee, what a shame. So bees are hemimetabolous. Are there really bees? There is no such thing as a tenacious version of a bee. Are there really bee cocoons? Nothing, dear. Bees
1:12:25 are always like that from birth . How come the bee's metabolism is holo? How does bee metamorphosis occur? Yes, there is, Sis. I'll make it later. Whatever. Then the parthenogenesis number. What is parthenogenesis? Parthenogenesis is a condition in which there is an ovum. Come on, parthenogenesis. Parthenogenesis means that an animal's ovum is not fertilized. Wait a minute, let's focus on writing first. Parthenogenesis is when an ovum is
1:13:14 not fertilized. the ovum is not fertilized, the ovum is not fertilized by sperm. If the ovum is not fertilized by sperm, it should not develop into a new animal, it should not develop into a child. But parthenogenesis is a condition where the ovum is not fertilized by sperm but develops into a new animal. Well, that's parthenogenesis. Do animals perform parthenogenesis? Hmm. Uh, do animals, do bees perform parthenogenesis? Can unfertilized bee eggs develop into
1:14:00 bees? Yes, the answer is yes. Well, yes, you can. Bee eggs. Unfertilized bee eggs can hatch into bees. But it will definitely be a male bee. Well, this is what is unique about bees. So, unfertilized bee eggs will definitely become male bees. But if a bee egg is fertilized by sperm from a male bee, it means it will become a female bee. So who is the father? There aren't any, dear. Male bees only have mothers. Hehe. May I ask something, Sis? If you Google it, it says holo bee, not Hemi. Wait, let's check
1:14:45 Google, okay? Because maybe I'm the one who's wrong again. Maybe it was me who forgot. The bee is holo or Hemi. Come on. Hmm. Actually, I'll just keep quiet for a while while checking. H h h h h. We'll look for that holo later. Oh, sorry dear. Sorry dear. The bee is a
1:15:30 holo. The bee is a holo. Sorry dear. So number two didn't turn out to be right, UGM's dribble, good morning, sir, bang [Laughs] dungding, ouch, ouch, ouch, hey, honey, honey, I'm only human, honey, I'm not a prophet, so I'm not always right, sometimes I slip up. Bees are holometabolous because they have a larval phase that is like a small worm. I just remembered
1:16:17 that bees are similar to ants, right? Ants have a small larval phase that is similar to caterpillars, like the maggots that people usually eat. Then I remembered, oh yeah, bees also have larvae that look like small caterpillars that people sometimes eat. That means hello, dear. Sorry, honey. Excuse me. Forgive me. That means big brother holo. I'm sorry. I'm sorry. Oh, it's embarrassing to dribble it myself. Ng ning nung ngang ning nung. Hello, hello, my dear. Hello hello hello hello hello
1:17:03 ha. Hello. Hello. Hello. Hello. Okay. Okay, let's continue . Let's continue, okay? Number four. Piercing and sucking mouth type. Wow, sometimes insects are also differentiated based on their mouth type, dear. Yes, but if we pay attention, if we think using logic, yes, the mouth of a bee is piercing. Huh? What do bees sting ? What do bees sting me with, honey? The job of bees is to suck flowers and suck nectar. Do you really have to pierce it first before the nectar comes out? No need, honey. Just lick it. Just suck the flower nectar. Hey, have you ever eaten
1:17:48 nectar from flowers? It's just for fun if you find flowers on the side of the road. Pick the bottom part and suck it. It's usually sweet. That's nectar, honey. Just suck it, no need to stab it. Never, just by myself . Oh, who cares? Hibiscus. That's right. Hibiscus. That's right. Just pick the bottom and then suck on the bottom, it's sweet. No need to stab, dear. The ones that stab and suck are mosquitoes, honey. Yes, the mosquito's mouth is piercing and sucking. So, he pierces your skin and sucks your blood. Eh, that bee. The bee's mouth is not a piercing one,
1:18:34 dear. Bees are suckers, yes. A sycophant, yes, that's it. So, the answer is B. The answer is B. Still, the hero is wrong. That's right. It's the bee that stabs with its tail, honey, not its mouth. That's right. The bee stabbed with its tail, not its mouth. Yes, so be careful. Ouch. Yes, that's why next time when we study biology, we should go on an adventure outside. If there are flowers, pick them and suck them to see if there is nectar or not. Try it, Sis, if the Frangipani flower is really scary. Can we just use normal flowers,
1:19:20 not the frangipani flowers that are usually used on graves? Oh, it's bitter, Sis. Is the corpse flower too much , Sis? Oh well, whatever. Just you guys. You guys do it. You guys do it. Up to you. Sis, try the rafflesia flower. Just you guys. Just suck it up until the end of the world. Those damn flowers, huh? Oh my, this is not right . So number 6, the answer is B, my dear. No, the answer is A. Sorry, because it turns out that bees are holometabolous. It has larvae that look like small worms. That's very different from adult bees, isn't it? Oh, glow up is really meaningful. Holo metabolism. Sorry if wrong. Sorry if wrong. Please continue, darling. Please continue.
1:20:07 Next question, yes. Number 7uh. Ouch. Ouch. Please, dear. Please, dear. Members of the echinoderm family are considered to be bilaterally symmetrical animals . Because echinoderms go through a larval phase which has bilateral body symmetry . Hey, please answer. This time I won't be fooled. Ouch, that burp was really loud again just now. Ouch. E C D C A E B A C. Come on, please answer. Please answer. C. Fix C. A. A. Hm. A B C D.
1:20:52 Oh, of course not. Just pick one, honey. C B C E fixed dare to be different. Participate in the most votes. A, that's called cheating. B C C. What did Hirono answer, Sis? Hirono was asked. Oh, Hirono answered A. Yes, Hirono answered A. Are you team Hirono or team Hoba? If you want to choose, Sis, it's fine. No way, honey. You can't choose me, okay? I'm not Anjas's choice. A a Brother Bagus said it was a starfish. So what does starfish have to do with this, dear? Yes, Echinoderms are a
1:21:39 group of starfish, but how do you answer this question? Come on, the top one is already very clear, dear. Members of echinoderms are considered to be bilaterally symmetrical animals. Echinoderms, for example, starfish. How many axes of symmetry does a starfish have? How many axes of symmetry does a starfish have? Are there many? Do starfish have many axes of symmetry? Here one can, two can, three can, four can, five can. Oh, so if there are many axes of symmetry, it means it's not bilateral, right? It's a shame, it's radial.
1:22:28 A was dribbled by UGM. Nang ning nung nang ning nung sir gulip bang dungdingser. Oh my God. So the answer above is clearly wrong. When echinoderms are adults, their bodies are radially symmetrical. Radial because there is a lot of body symmetry, dear. But do you know why echinoderms are included in the bilaterian group? Why are echinoderms considered bilaterians? Yes, yes because it is a triploblastic embryo. It has three layers of tissue. And when echinoderms are still young, when echinoderms are still young, aka still
1:23:13 in the larval phase, the larvae are actually bilateral. So the answer is ee Ah.
1:24:25 Little by little. Oh, I'm so sorry, my internet farted so it suddenly got kicked. Is this why I'm not the host? Wait a minute, I uh yeah I can't do this. Wait a minute. Oh, I've been the host. Thank you, Wulan. The host earlier was Wulan. Thank you Wulan for returning it to me. Sorry, my internet farted so suddenly the zoom just went off by itself. After the evil laugh immediately disappeared. Yes, that's how it is . Is that so? So the answer to number 7 is D, my dear. The top is wrong, the bottom is
1:25:11 right. So the answer is D. Okay, let's ask another question. Well, that's it, that's it, honey, there's another problem. Hmm, there's another question. In the phylogenic chordata, the group of animals that are in the same branch as mammals based on the presence of amnion is who has amnion nang ning nung nang ning nungkinodermata the answer is d. The top is wrong, the bottom is right. Come on, question number 8 please. Well, let me give you some pointers. I'll give you a hint, okay? The amnion is a membrane that lines the amniotic fluid.
1:25:56 Well, now you have a clue. Okay, just think about it using logic. Which other animals have amnion lining the amniotic fluid besides mammals? Diggcek UGM nang ning nung nang ning nung pagulipak bang dungdingser Mustofa. Come on, who else has a membrane fluid lining the amniotic fluid besides mammals? Who else has amnion besides mammals? He, if one piece chess. Pis ches is a fish, right? Hey, do fish really have amniotic fluid in their eggs? Where is it? So number one is clearly
1:26:42 wrong. Continue amphibious. An example of an amphibian is a frog. An example of an amphibian is a frog. An example of an amphibian is a frog. While frog eggs do have amniotic fluid, they do not have amnion. So the ones that have amnion are reptiles and birds. That's right. The answer is C. Oh, here I am to cheer you up. Sing and dance with you. Aves is a group of birds, dear. Aves is a group of birds. Not to be confused. That's right. Those that have Amnion are usually large eggs . Reptile eggs have an amniotic membrane. Bird eggs, aves
1:27:29 also exist. But mammals don't lay eggs, Sis. There are mammals that lay eggs, but not all of them. If you see that she doesn't lay eggs, is there amniotic fluid? Of course there is one in the womb. Uh, yeah. Well, we have to learn this too. We have to review this. Crocodiles lay eggs, Sis. Crocodiles are reptiles, honey. Crocodiles are reptiles, honey. Crocodiles lay eggs. Have you never seen crocodile eggs? Ouch. Yes, amnion is the fluid inside the egg. Amnion is amniotic fluid, which in everyday language is amniotic fluid. Usually, when a mother is about to give birth, her amniotic fluid leaks, right? Well, that membrane that lines the amniotic fluid is called the
