0:03 Hello students, welcome to all of you. This channel of ours DNS. kids are here today In this live session of we are going to discuss These are the most 50 questions which Previous year and memory based questions are going to stay and especially this session today This is all of us from Lucknow University Its B.Sc. is based on Questions may come in the entrance exam of Are. Children, I have come live. Today's I have started this session. all in a jiffy Join the session and as many children as you want I have joined all the children good Evening. Quickly share the session with the children Do it with all your friends Who is with all of you this time at Lucknow University Those who gave the B.Sc entrance exam Are. So children, let's go to today's class We will discuss 50 questions. step up

0:50 that everyone has to participate and all the answers Everyone here will give me whatever questions they want We are going to discuss and this is your Lucknow for the university entrance exam He is going to be very helpful. I understood the point Is it happening? So join all the sessions immediately Brother. are going to discuss here and these Your Ok. We yes however if I talk about the rest about the college entrance exam

1:36 Even kids can watch this entire session till the end. Are. Isn't it? brother the question is It doesn't come university wise. Isn't it? There are questions in all entrance exams Almost all questions are asked at the same level. Whether in State University Lucknow Be it a University, Gorakhpur University, You should have a UP College or Vidyapeeth here yes, okay? Harishchandra PG College, Whatever be the colleges, all of them have B.Sc. What is the importance of Bio in entrance exam? Those are the important questions in today's session We will discuss in. So for all of you It is going to be important. Lucknow only Those who are preparing for university It is not for them only. Is it okay? Ok? Come on kids, without delay Let's go ahead in the session and discuss it These are the important questions of today. Come

2:22 Let's start. The very first question What is in front of you? Asking for protein Digesting enzymes, which are Found in gastric juice. now here But if we look at the word gastric then Gastric means stomach in children. And there is this juice in the stomach, ask inside it that the protein breaker which Which enzyme would that be? In the options you you can see there's trypsin, chymotrypsin There is pepsin, and there is steatsin. To you I want to tell you that protein digesting enzyme which that is found only in the stomach Is. Many children may get confused here. Between two options. I am able to understand Must be. But let me tell you here Name the first enzyme that children should know It is written that trypsin is a protein Digesting enzymes are definitely present but this was found

3:09 Where does intestinal juice go? It is released from the intestinal gland Isn't it so, this option will be eliminated automatically? It happens, now the options are left for you chymotrypsin pepsin and steatsin quick will you answer this first question, right Come on kids, answer this question and Name the enzyme which digests proteins as well as It is also present in the juices in the stomach. Is. Children, did you see trypsin here? It is found in intestinal juice. And what does he do? this right here is pepsin We can call these proteins. Pepsin Joe It is an enzyme which is a protein

3:55 This finally breaks him. Ok No? And what does he make? amino acids Makes it. But protein in the beginning Who does the work of breaking it, children? Pepsin does. and this is the enzyme that It is present in the stomach. Is it okay? and Stipsin and Chymotrypsin options Elimination happens automatically. So pepsin This is the correct answer. of first question What will be the correct answer children? Option It will become C. This pepsin is mostly found in children It remains inactive but activates it is an acid found in the stomach whose name is HCl hydrochloric acid So remember this also, ask the question in this manner You can also ask how protein is digested Who activates the enzyme or what It is active at pH so remember that It is active in acidic medium and

4:41 Acidic medium is made of substances like HCl It is obvious that it is between one and two is found then at the pH between The enzyme called pepsin is active breaks the proteins of. Ok No? Let's move on. and kids try We will tell you that the comments made in today's session The questions you are asking are in the box For now, I am related to the topic Ask questions. You can ask these questions to your Save it for later that you get the entrance Which question will come in the exam. What What type of paper will be made, how many MCQs will be there yes, which chapters come? because in We have made videos on everything. If you visit our channel, you will You will find many such videos which will help you in You can clear all your doubts. For now, whatever doubts you have in this session

5:27 If you want to clarify anything, ask these topics. Is it okay? So this is for you and for me It will be better for both. Let's move on and we talk now about our of the second question. what is the second question Have you given it to the children? who has come here cells of the pancreas that produce glucagon Let's produce kids. So glucagon It is a hormone in itself. Isn't it? and this Where is the hormone produced from? From the pancreas. where is the pancreas found Is? Many times he asks this also. So remember that It is a leaf-like structure that first of all the sorry intestine of the stomach It is found in parts. and this The first part of the intestine is called the It is called duodenum. what do you say? Duodenum. and it is presented here Pancreas in loop. Now the children who Pancreas is made up of a special type of cell

6:15 It is made. This is called Izlets. Izlets Off Lagerhats. Is it okay? Now you can find two types of cells in it Let's go, children. Alpha Cells and Beta Sales. Now these two types of cells are of two types Make hormones. There is a hormone Children have glucagon and other hormones There is children's insulin. what in this question Have you asked? In this question it is asked that Glucagon is produced by which part of the pancreas? What is produced from cells? In the option Alpha, Beta, D and Gamma cells. Ok? The delta should be there though. So, Alpha Beta, Delta, Gamma cells out of all these From which cells is it produced? These He is asking. Answer these questions quickly I will give. Come on, I am telling you by doing Rockstar,

7:02 From Alpha Cell. let's see if this answer is correct No. Ok? Look kids, here I am Told about alpha cell and beta cell. would now What is it that a hormone is made from beta cells whose name is children's insulin and alpha Glucagon is secreted by the cells. Is it okay? So these are two types of hormones. Now here you have asked which glucagon is it? Is there sales? So it is a very obvious thing The answer will be Alpha Sales. Is it okay? It is from the alpha cell only and total The Islets of Lagheras speak. where this from Two types of cells are found. Both What is the function of hormones, children? This too Remember this. the glucagon here is Maintains the glucose level. Ok No? And insulin also controls the glucose level Maintains the . means in the body We have sugar to maintain it

7:50 Both these hormones work together. Now What happens is that the glucagon is our what does he do here? Glucose in the blood decreases the level and maintains it here The work of maintaining the cells of the body It is made of insulin. So this is in two ways remember the hormones that work I will keep it. Let's go ahead and let's grow Towards the third question. The third question is Where are Leydic cells found? Are? This question is being asked here. The options include ovaries, testis, air or eyes. Now let me tell you children that this human This question was asked from reproduction chapter And look, this is ours from class 12th There is a chapter. it is just in the beginning chapter and here remember that children These are the two types of sex organs Out of which we call the male sex organ testis.

8:36 and we call the female sex organ Owari says. here are some sales That are specifically found in these organs. For example, if we talk about testis, here But there are some tubules which It is called seminiferous tubule. Isn't it? These That is the place, children. these are the tubules inside which there is actually sperm Formation takes place. and for sperm formation Mainly sales people are responsible for this he is here kids But we have one Near Spermatogonia. what is here? Spermatogonia. spermatogonia which is what does this do? Sperm is produced and Ledic cells, what are these kids does it? its work is done here To provide nourishment. Who should provide the nutrition

9:22 Brother? the things that are taking form here and What is happening form? Sperm formation is going on Used to be. So the work of nourishing it Whose is it? Leddick cells Is. That's why it's here several times for one minute. Leddick cells which are present in children produce hormones. whose name is Testosterone. Testosterone. Nourishment work basically It is given to the Serratoli cells. Nourishment To whom is the work given? Ceratoli To Sales. This provides nourishment. Is it okay? The main work of ledick cells is to make testosterone. Correct? So these three Sales have their own work. Seminiferous Sperm formation in the tibule. Leddick Sales testosterone androgen here inside Hormones are produced that regulate male sexual activity Is responsible for the character. there if

10:07 If we talk about Setoli Sales then this provides nutrition so that the sperm is It should have proper formation. So here it is Asking where to find the Lady of Sails Will you go? Answer this question quickly. yes Rashmi correct answer is what about third Will be done? It will be B. Exactly. be is The correct answer. what will happen its correct Answer? B, right? Testis. Correct? So this is this types of cells are found. Now look and also if it comes from here that which ones What do sales people do? So are the rest of the sales. Remember the work. Like if there is ovary then for ovary Inside you will see a Graafian follicle forming Is. The primary secondary follicle is formed. And What do these follicles do? estrogen name which produces hormones in the female body It is made in. Is it okay? So remember this too You guys keep it. Correct?

10:53 Yes. Come on Vartika, what are you saying brother? B I am telling you. It is perfect. let's go with this Let's move on to our fourth question. The next question is about children's estrogens Where do the secrets come from? just a little bit I mentioned this a while ago. Tell me Secrets are produced from the ovaries and testes secrets are from the pancreas or pineal From the gland? Look kids, the pineal gland which isn't it, it produces a hormone which is called is melatonin. what do you say? Melatonin. And this is the melatonin hormone Nor does it decide our internal clock Is. That is, when do we have to sleep, when do we have to sleep Waking up is a maintenance job for this thing That's what melatonin does. in the female body Also controls the bicycle. all of these The work gets done. with it our skin color This hormone decides. so these hormones It comes from the pineal gland. Is it okay? Now but here's what about the pineal gland

11:39 I have not asked. You can take something like melatonin You may not be able to see the mention of the question In. The hormone in question is estrogen Name of. Now you have asked who keeps this secret Is? Ovary of the testis. it is an obvious thing You must have known this much that this is your From sex glands or sex and organs These are the related terms. So tell me quickly What will be the answer to this question? Forth Answer to the question. Let's tell you the question What will be the correct answer for number four Children? Tell me. We have just discussed ovaries did you kids? if the testis remains in the child then the seminiferous tibule would have been either asked or So it would have been written spermatogonia or lady cell or setoli cell i can't find anything like that if it is there then we can say that testis it is not secreted from testis right the testosterone hormone is produced Is ovary the correct answer or not? from the hormone called estrogen

12:25 He becomes ok nor any children's questions that are there They are not hard. just you are good Read your NCERT book. class 11th Read NCERT. class 12th ncert Read it. The questions have to come from there. If You have not read NCERT properly. If you have not cleared the concepts then you Topics or whatever question will be asked They may seem a bit tough in exams. Correct Isn't it? So the correct answer is children's ovaries It happens. Coming to the next question Are. The next question is which stage In which stage of gametogenesis in Does miosis occur? He is asking this question. Now let's talk about gametogenesis of children What is gametogenesis? then remember Keep the gametogenesis of children safe What is the process where it happens? Gametes Formation takes place. What happens? Gametes

13:13 Formation takes place. Is it okay? So the gamete There are two types of formation here Gametes are formed. one is the male gamete which we call sperm and a female The gamemate is what we call the egg. when both of them If formation occurs, then miosis should occur in it It's fixed. But the question here is asking this which stage will come in which actually Miosis will occur. Why is miosis needed? Does it fall brother? So miosis is needed because It falls so that it becomes half. What? be half Go to chromosomes. There may be half chromosomes. What happens because of this? Miosis occurs. Ok? So here I have asked which one is that There will be a stage. now it's here in stages Multiplication Fuzz, Growth Fuzz or Maturity Fuzz where it's fully formed Go gamemates. When will this happen? when their number It increases when a growth is seen inside them

14:00 or when maturity is achieved in them Is. In which phase will meiosis be seen? Answer this question quickly I will give. Let us go. let's say good rashmi fire god gaming maturation face very good children correct answer Is. Isn't it? Maturity fuzz is where Actually miosis occurs. right here The chromosomes are cut in half. after all If the chromosomes are not halved then two gametes will form when they come together and bring a new baby or a A new zygote will be formed. So think about it How much will the chromosome number increase? So this is the reason it is necessary that during gamete formation meiosis to occur so that the chromosomes are It should be half. Like in our body your There will be 46 chromosomes in the body at this time. But the gamete will also have 46 so the male gamete

14:47 in also 46 in female gamete also 46 both chromosomes come together The chromosome number will become 92. Now Not every child has this many chromosomes In Generations. So because of this, chromosomes The numbers remained constant. miosis because of this It is necessary to have it. 23 comes back then it will be 46 Chromosomes will go to the new baby. Isn't it? Let's come to the next question. The question is a little easy. asking a question Which cell organelle is called suicidal bag? They say? That means he commits suicide. There comes a time when this suicide He tries to do it wherever he can It goes in and eats up the whole cell. When That cell is about to die. Now he Which is a cell organelle? He is asking this. Options are ribosome, lysosome, karyosome Or chromosomes. Tell me.

15:36 I will tell you the answer to this question very quickly What will be the correct answer? which cell What is the organelle called suicide bag? Look kids, there is a ribosome. Ribosome is a protein which We know them by the name of factories. What Do you call this? Protein Factories. Why? Because they form proteins. Is it okay? Besides, if we here If we talk about chromosomes then we know chromosomes Everyone knows that it is genetic material. What is this it? genetic material that a brother has It definitely passes from one generation to the next. now next here is lysosome and Karyosome. I have to tell you about suicide bag in Which of the two is it? I will tell you quickly what will be the correct answer of this question Children? Name which cell organelle

16:21 It is called a suicide bag. remember this kids Its answer will be lysosome. yes lysosome There will be an answer to this. Why? because inside it An enzyme is found which we call It is said that the name of this enzyme is Hydrolytic enzymes. What is its name? Hydrolytic enzymes. and this enzyme What is the speciality? that this is any thing It breaks the . convert into smaller particles He does. then it is also called dustbin of sale Are. Because it also cleans the whole cell. keeps it. Keeps it clean as well. at the same time It is also called suicide bag. Ok No? So these two names are reminiscent of lysosomes. I will keep it. for example if there is mitochondria then it It is called the power house of cells. As There is plastid in it chloroplast is called kitchen It's called House of the Cell. Similarly, lysosome to the suicidal back of the cell and the dustbin of the

17:07 Sale also disposes it of as waste disposal of Also known as cell. Next The question is our disease which is caused by Vitamin C It happens due to deficiency of. name of that disease I have to tell you. This is a very easy question. You This is not the first time I have read this question. Tell me Beriberi, pellagra, scurvy or rickets. Which disease is caused by deficiency of Vitamin C Is it kids? Quickly I will tell you. Let me tell you its answer now Are. Let us go. Yes. Ok. That is the answer for everyone Correct. There will be lysosomes. on this question Come and tell me. due to deficiency of vitamin C What happens to the children? quickly me

17:53 I will tell you. Watch children Vitamin C deficiency what happens from this? Scurvy occurs. Ok No? will remember the disease called scurvy which It is caused by deficiency of vitamin C. Next Let's come to the question. next question is An egg that has a yolk. what is yoke Is it kids? that part inside the egg That's where the yellow portion is, right? Is it okay? That which is the yellow portion. What do we call him? Yoga speaks Are. Is it okay? this portion where Yoga happens. Now this question has been asked Children, if there is an egg which has a lot of There is not much yoga. Not too little either. Correct The sum of the quantity present in it Is. So we can do this type of yoga like this What would we call this whole type of egg? The option is elixithyl,

18:40 microlisithyl and here mesolisilthyl and Megasthal. Now look kids you won't find anyone here These terms have to be decoded. Meezo micro mega tell me what is micro Children? We call small things micro I say it. Mega refers to big things. Mezzo refers to medium things. Now from this Think of an idea and tell me how to make such an egg in which the yoke is too much and too little No, it is in medium amount. So to him we What will people say? Yes karvy is the correct answer. Tushar is perfect There is an answer. Let us answer this. Children will answer question number eight that x which has moderate sum what is it Will you say it? From Micro Mega and Meezo Word Take it out and try to tell the answer

19:26 Children. You will get its answer. Micro Mezo or Mega? is lestehil which one is this This will come in the category in which yoke is moderate Is. So kids, remember this, We call it mezolesthil here. Is No? In between there is a moderate amount of not much Neither too much nor too less quantity is there in the egg. Is No? So its correct answer will be C. This Let's move on to the next question. ask that the length of one helix of DNA Yes, what is its length? if these I would say it is DNA. Now there is a lot in DNA too All the questions that you will face in exams Ask in state level entrance exam Can. Now a question arises in this what is the formation of dna called Are? So, someone knows the DNA here What is the formation called? Someone tell me

20:12 Can I have this thing? The formation of DNA, children, When DNA is ready, is formed, then it is called what do you say? This process is called Kids Transcription. Is it okay? What speaking Are? We call this replication. When DNA is made from DNA. Isn't it? When will the transcription speak? When the DNA Children, RNA will be made. What will be made? RNA. We call RNA formation Transcription. where is RNA from DNA It gets ready. and when there is RNA kids then This will further produce proteins. then from RNA When the proteins are ready, this process What do we call it? This we people Children say translation. what do you say Are? translation. So sometimes these three terms also appear in the exam. Replication,

20:58 Transcription, translation. From DNA If DNA is formed then replication will happen sorry yes If RNA is formed from replication DNA then here when transcription and RNA are made into proteins If it is made then remember the translation here But you are asking about the length of one helix, right? When starting from one turn to the next turn the length between starting it is now considered a helix What is the length of this helix 120 Armstrong's 34 Armstrong's 40 how many amstrong's 68 amstrong's Its length is . ask you this It has been in this question. Quickly this answer to the question I will give. come on 34 amstrong one people are saying Yes Tushar B is here B is telling.

21:43 yes very good. The answer of two people is correct here Is. 34 will be Armstrong. if the children If the question was changed a little bit I would have asked more. the length between two base pairs Tell me. Do you understand two base pairs? Means DNA Nitrogen bases inside the children like this Is found. Isn't it? where adenine, Thymine, bone, and cytosine. So if asks the length between two base pairs, two base If I ask about the length between the pairs, what would it be? go? It would have been 10 times less. So this is it Ours goes to 3.4 amstrons. Are you understanding? So in this way this question is also related to length can be asked in different ways. So yes. All the kids, Abhishek is also here I am telling you answer B. As many children as I am telling you the answer, it is absolutely correct. 34 Amstrong. Is it okay? let's go with this Let's move on to our 10th question. 10th

22:28 The question is, children v part of the brain? Which part of the brain is it But muscular coordination works? Muscular Do you understand coordination? Muscular Coordination means how your muscles work together will it work that way? he controls her Who is it? Which part of the brain is that does it control? kids remember your brain consists of three parts Are. Fore Brain Now look, now that you have been taught this topic yes, if you have seen this question then What do you have to do? to you when your I want to prepare for the competition exam, So you have to cover this entire topic. You can't just memorize the answer to this question I have to go to the entrance exam. this is it here Some children make mistakes. Now when you know It is now time to ask a question related to the brain

23:14 If you know it, then you will get complete brain topic cover. Have to do it. What will happen with this? Alternatives to this Even after doing this, some questions will arise, so You won't have any problem asking questions In. Now as I am telling you, the brain There are three parts. the fore-brain, the mid-brain, and Hind brain. Isn't it? Now what would happen in this Is? what does our four brain do Is? How much is our intelligence? Our How is the IQ level? how do we reason Can you? i.e. how is the ability to reason Is? All these things are from our four brain. There is control. and who is that person of four brain Which part is it that controls? The cerebrum. Isn't it? Now you can see Cerebrum is written somewhere. It is written here. But now this is not being asked here. Here he is asking about muscle coordination i.e. That is voluntary action. such actions which our His voluntary actions are under his control

23:59 They say. Now who controls that action? Is? He is asking this here. Involuntary If we talk about action then Hindi Who does this in the brain? the medulla does Is. who does? Medulla. of the hind brain One part of the body is called the medulla. that this It works. Is it okay? that involuntary Action like I suddenly sneezed let's go. Isn't it? Sir, you may start coughing. so this it's something you can't control Are. Isn't it? So this is the thing. so who is this does it control? medulla involuntary Action. Now, the question which is asked is Control voluntary action. like your muscle There is a movement of. I want to move my hand This is in my control. my hand itself It will not move. I don't walk on my own I will start running. Isn't it? this is in my control Is. So who does that, kids? it does The cerebellum. Isn't it? Isn't it? which is hind brain This is the second part of Again. another part

24:45 It happens Ponce. These are the three parts of the hind brain Of. Isn't it? So remember this, kids, The cerebellum is responsible for ventricular action He controls it. yes very good. Coronation The correct answer is given here. vashu here It is on. tushar rockstar one by one d no will be. Yes D is the correct answer. Good. The cerebellum. D D is the correct answer. Cerebellum is given in D. so d is the Correct answer. Very good children. Let's grow On to the next question. next question is Which of the following are voluntary muscles? See Children, there are only three types of nerves in our body There are muscles. One of the issues that we Found in the arms, legs or diaphragm. Like our skeletal muscles. these muses We move according to our own convenience. So this is They are called voluntary. There are other muscles Smooth muscles that are inside our organs

25:31 fills the space and throughout the body They are found in our digestive system. These Our work does not work under control. And the third muscle is cardiac, which It happens specially only and only in the heart Is. Now who is asking here Are you voluntary? Voluntary means the muscle which Work according to us. Tell me Quickly. What will be the answer to this? Very good children. Everybody got the answer right Had given. We will answer this 11th question Children. what is the answer to this Will you go? Telling about the educational life of 11th Are. Tushar is explaining skeletal. BTC And I am telling you all of these. all of these How it will happen? I just told you kids That our hands are smooth and cardiac They do not work under control. so this

26:17 It was not voluntary. He was involuntary. Who doesn't work according to us and that It's smooth and cardiac. it's both of them What are they coming for? come under involuntary Are. Isn't it? which does not work according to us Do. So they obviously come. its correct The answer will be A. Isn't it? as many children as The answer given by A is absolutely correct. Not smooth A is the correct answer. Skeletal This is the correct answer. Let's move on to the next On the question. The next question is children. What type of renal artery is present in our body? supplies blood? Look at the blood, kids There are only two ways. There happens to be one Oxygenated blood is the second Deoxygenated blood. asking here now what type of blood is that renal What does the artery supply? look here kids Remember some terms. Such as Renal. Renal's Meaning there is no kidney. Cardiac.

27:05 Cardiac means almost all the children You must be knowing. Right? What does cardiac mean? What happens children? It is heart. Right? So this is a heart here. Apart from this, if we talk about lungs So what do we call lungs? Lungs We call it pulmonary. Is it okay? So these are some of our body the parts are like this the parts of the body are like this Which has also got other names like alternative. Now He asks him questions many times. As he will say many times that the pulmonary disease here Is it an artery or a vein? To whom will it donate blood? So You must remember that pulmonary means Mam told me that if there are lungs then It will be related to the lungs. either in the lungs It will either take blood from the lungs

27:52 will come. So what will be the answer to this? Big It is easy. To whom is renal artery blood supplied? will he do it? Tell me quickly. please tell me the answer of 12th The kids are living here. What do you think? It would be a kidney. Let's C 12th Ka B Rockstar Educational Life Tushar Kidney Kidney. ok good. kidney This is the correct answer. Isn't it? From Renal Word Decoded it. Isn't it good? so the kidney is It supplies blood here. Renal artery, renal vein. Similarly, the liver which what is the word for this guys Children? What is the word for liver? It is a hepatic word. what is the word? Hepatic. Isn't it? remember this word for liver Keep it. There is a spleen. Who are called Gonats? Are? To the sex organs. such as the testis, Ovaries. These are gonads. where at Actually he becomes game mates Gonats says. Is it okay? Let's move forward

28:39 Let's increase. On the third next question. 13th asking the question whose glycogen is this Is it a polymer? That means this is a big It is a complex structure. inside it What are those simple things that A glycogen has been formed by combining? Option Contains Glucose, Fructose, Mannose Or galactose. Who is the simplest sugar? What happens children? If you have this question If you know the answer then you will know the answer to this question also. The answer must be coming. Tell me quickly. Glycogen is a polymer of what? I will quickly tell you the answer to this question. Let's use glucose. Ok? some people here B is telling. Some people are saying A. What do you think kids? The answer is glucose will be. Isn't it? Glucose which is the simplest

29:25 Glucose is the simplest carbohydrate And its formula is C6H12O6. As its units are continuously added, They go away, this creates a complex The structure gets ready. like two What is formed when glucose is added Is? Sucrose is ready. Now Sucrose Whatever is prepared, this is a little There is a complex. what is its formula It happens? C12H2O1. So remember this. This is a little bit It is complex. If two glucose is combined then one Sucrose will be ready. Similarly, glucose When big long chains start getting ready So what is prepared from it? Glycogen Starch is prepared. starch glycogen Starch is found in plants. Our This sugar enters the body when we eat too much It happens when there is storage in our body If yes, then it is stored in the form of glycogen

30:10 It happens. Is it okay? Is it okay? so the correct answer is yes as many as Even the kids are saying that it is absolutely correct. Prayer Rockstar Education Life is perfect. A This is the correct answer. Let's move on to the next On the question. next question is What is the main source of progesterone? Progesterone is a hormone in itself. Which is found in the female body. This The level of hormones in our body It keeps increasing and decreasing depending on the whole Which phase of the month is going on? Is it okay? So I am asking what is the source of progesterone That is, where does progesterone actually come from? It is released. Ok? so the first option is Pancreas. In the pancreas I I already told you guys that it is from pancreas

30:57 insulin, glucagon, and if this is a exocrine glands instead of endocrine glands pancreatic juice works like this produces two types of There are hormones. either trypsin or So it will be either lipase or amylase. And Secondly, I have already told you about starting in session that it also contains glucagon Yes, it also contains insulin. Is it okay? So there is nothing like that in the question Progesterone is asking the question So the pancreas will be eliminated. Next is the pineal gland. kids this too I told you I told you at the beginning of the session that no which one is from the pineal gland Does the hormone come? commenting quickly tell me. Children, you guys are here for the entrance exam

31:43 ma'am you are asking a question related to In this particular state university, In particular entrance exam this Does the subject combination come or not? Is? So children, for this you can visit our channel There are lots of videos presented Go and see that. Is it okay? at random When you ask these things, many Universities are such where the subject The combination is different. Many universities are like this is where others are. So, in such a situation, we have to At times we don't remember these things that the subject What are the combinations? So for this you better have videos for this Go and watch it on the channel once. Correct Isn't it? Come on kids I told you guys I asked which hormone does the pineal gland produce? produces it? Or does anyone remember? I told you about the session in the beginning itself Was. Tell me quickly. I do not remember anybody To? I had mentioned in this that the pineal gland

32:30 From this comes a hormone called melatonin. What? Melatonin. Is it okay? So this too Will not done. Next is thyroid. Now everybody has You must have studied from very small classes that in this Thyroxine is produced. and last in the corpus luteum. Which children are there Who is telling about D option. as many people as Its answer D is giving absolutely correct. Ok? Rockstar, Smart Boy, Tushar, Vasu is absolutely right. D is the correct answer No? Corpus luteum. brother this is the question The question arises whether there is a corpus luteum? So children it is found in the ovaries and The corpus luteum is formed when Ovulation has already occurred. That is, when from the ovary Once the egg is released, what happens next? it happens not that there is a large follicle when An egg comes out of it, so this follicle What happens gradually? seems to shrink Is. It starts becoming smaller in size. And this which

33:17 This is a structure, we call it a corpus luteum. now when this corpus latium is formed So it's a lot of hormone in the beginning produces and that is a hormone Progesterone. When is it needed? This is required by the uterus. the innermost The lining should remain in the same place This hormone is necessary for. Why do you have to stay in the same place? Because if this The innermost layer of the uterus is If it does not stay in its place then that blood break By doing mucus and unfertilizer sub vaginal will go off the track. which we Menstruation or menstrual blood flow also I say it. It will begin. Its Clearly this means that the decrease in progesterone means the start of the manual cycle and Increased progesterone levels mean that The mention has not been started. And you

34:04 you will see that in a pregnant woman progesterone levels are high Are. Exactly our education life is like this We will bring more videos from here. Isn't it? This way You will get MCQ sessions from time to time From. Yes, the corpus latium will degenerate later on It does and d its ending. Corpus Degeneration of the luteum This means decrease in progesterone. And When progesterone decreases then only the manual cycle will start begins. so remember these things too Keep it. So corpus luteum is correct There will be an answer. Let's move on with this to the next On the question. The next question is children. Gaseous transport in mammals occurs when Such as CO2 so what is its main form

34:49 Of being transported? means the most When CO2 enters our body in this amount Is. yes now remember that only There is no transport of O2 in our body It happens. Things like CO2 are also transported it occurs. And it comes in three forms. Children. The first is carbon hemoglobin. This means that CO2 binds with hemoglobin and Carb amino hemoglobin is formed. Second is in the form of bicarbonate i.e. H2CO3 He does this after becoming one. Is it okay? Carbonic Anhydrase enzyme which helps in this He does. With the help of this these bicarbonates We get ready. and the third is in plasma This dissolved CO2 gets transported. So these three There are forms in which our bodies CO goes in. This is not in question now He is asking. He is asking the most questions In which form is it more? To all In which form would most transport take place?

35:35 Is? So the one which is the lowest in this will be in the plasma. it is more than that for children Carb amino in the form of hemoglobin. And The form in which CO2 is most abundant There is transport, children, that is it In the form of bicarbonate. yes its 25th 25th is not on 25th but on 15th question Children. what is the correct answer for 15th Will you go? What do you think? What will happen? A will be A, will be B, will be D. Is it okay? It is in the bicarbonate form, right? Children get confused with bicarbonate There are A and B and they make a mistake. So Remember the bicarbonate. Now this Can remember in alphabetical order. first comes b then c so carbon Hemoglobin is with the letter C and From bicarbonate B. So remember that In alphabetical order which is the highest B

36:21 That is, bicarbonate. in a lesser amount than comes C i.e. carbon hemoglobin and The least amount comes in D, i.e. In dissolved form in plasma. b c d Remember this in the format of. Ok No? So the correct answer to this should be children too Will go. Let's move on to the next question. See next question again class 12th that you have come here this evolution chapter There is a question from. is asking a question Mutation Theory Mutations in Evolution who gave the theory Was? Darwin is in the Lamarck option, Hughes and Mendel. Tell me who gave the mutation theory here Were there children? Answer this question quickly I will tell you. what will happen to this question correct ans? Tell me children. who gave the mutation theory

37:07 Was? What theory did Lamarck give brother? Lamarck says use and disuse of Organs. Use and Disuse of Organs. i.e that they say that if there is an organ The one that we use constantly is The organ will develop, grow and move to the next There will also be transfer in generation. but if If we do not use any organ then it It will degenerate. Like he gave the example The giraffe's neck was taken here as a gift. Isn't it? was taken as an example of That these people used it. That is why their The giraffe's neck would have been longer Has gone. Then there's Darwin. Darwin is so talking about natural selection Are. Now the mutation theory is being asked. So Who talks about mutation theory? Is? Hubo DeVries talks. Mendel What should we talk about? The Mendel thing Let's talk about generations. Mendel talks about

37:52 Law of Dominance, Segregation and Independence of assortment. then remember the rest Keep it children. Like Darwin, this Let's talk about natural selection. Isn't it? Remember this also. Hugo Didbridge Let's talk about mutation theory. they say Suddenly, there is a change. Long Term Change comes and it remains the same for many years Lives in population. It works. So to them this They say yes. Mendel drinks what he has Let's talk about plants. P The plant was used in his experiment Was. Mandel Manley talks about law. Law Like the Law of Dominance. That means any The character which is dominating is always What will you do to yourself? will express In the first generation. and the one which is recessive No, express will not do. So these things Let's talk about Mendel. Ok

38:40 No? Never mind Abhinav. Is it okay? so the correct answer is its hubo It will be debriefed. Let's move on to the next On the question, children. next question is When was the chromosomal theory of sex given? Determination of sex among humans How is determination made? The Big Easy This is the question. So everyone can answer. Humans have two types of sex chromosomes are found x x and x and. Now you Tell me quickly which option would be correct? Which gender is decided by X-V? Which sex is decided? and x What is decided by X? that would be the mail Will it be female? Tell me quickly. get it here kids on the chromosomal theory of sex He often gets questions about determination Is. like a very important question It comes to you every time, may it come to you this time too

39:25 Sex Determination of Exot Type In which does it happen? So remember this kids Occurs in grasshoppers. In which does it happen? Occurs in grasshoppers. Isn't it? other than that One to One and Another Type of Sex Determination It is of ZW type. what did you find this in goes? It is found in birds. So Remember this too, children. Isn't it? And One sex of the haplodiploid type there is a determination which is specifically It is found in honey bee. now i asked here This one is simple, it is a very simple question But if these two ask this, then remember this If ZW comes then remember it in Birds If it happens and XO arrives, then remember it. This type of sex determination in grasshoppers It happens. Let's find out the answers for 17 questions in Hindi They are coming continuously. Let's see that right No? XY in mail and XX in In the female. It's absolutely correct brother. very good. Abhinav Smart Boy Pooja Educational Life

40:11 Everyone is right, Tushar. There were also easy questions. Isn't it? need to feel very proud Not there. Isn't it? Rest of these terms which are given above It is given, remember this. if these If you take questions to the exam then You can feel proud. let's grow On to the next question. next question is The number of vertebrates that are present in the neck of mammals How many vertebrae are there? how much bones Reeds are found in the vertebral column asking for her number in the neck region of the bone Is. So how many neck vertebrae are there in children is it found? in a flash Tell me. Answer this question quickly will give that number vertebrae neck of mammals How much is it in? Is it okay? in a flash I will answer this question.

40:59 Thank you Swasti. Let's answer this question Give it. Number of Vertebra Neck Off How much is in a vertebra? then remember Keep it. Let's see how many people answer I am giving it to you. A is telling. Very Good. I was not expecting it but here is the answer. Good. There is a number seven in the vertebrae. Is it okay? It is consumed. and that is if we When people talk about thoracic vertebrae Thorax region. That means this is a matter in the chest region then how many are there in the vertebral column Are you coming? So then our answer is 12. They There are 12 bones. Isn't it? Remember this. Here is the intake in the neck. very good. Let us go, Let's come to the next question. Number of How many chromosomes do humans have? Very This is an easy question. Quickly answer this question Give me an answer. how many chromosomes in humans It happens? Just a while ago we had this If paired and unpaired then how many Will it be? All this was discussed. So tell me quickly. How many chromosomes are there in humans?

41:44 Are? Children, there are some questions whose answer is I need it quickly. so quickly do it I will answer. Yes, very good. it has been fair In our thoracic region, chest region. Exactly very good. Come on, this question Please answer. what is the correct answer for 19 Will the kids go? Yes BB is the correct answer. Who? 22 is written. 22 will make 23, right? And 23 will be in pair. Here is the pair There is no conversation taking place. So it will be 46. Number Speaking of chromosomes. See Same thing happens. Sometimes you are very simple They make the question wrong. Isn't it? So There are 23 pairs in our body, which means 46 numbers. Chromosomes are present. then correct Answer It's going to be B of 19. B is the Correct answer. Let's come to the next question Are. Look here at the names of some enzymes It is written, children. Now you have to tell that the odd Which of these is a forest? which one of these

42:31 Is it the odd one out? I have to tell you this here. Odd Which one will be one out? pepsin, tilin, vasopressin that Trypsin. Is it okay? Now let's talk a bit Which enzyme is where? By this we You will be able to find out which is the odd one out. However you will continue giving your answers. yes 23 in pair will be. What is Mukund saying? mam dd Will also provide B.Sc Biology. Absolutely well you reminded me of DDU This session will be fine tomorrow in the evening time Whatever is there tomorrow will be there for DDU, it will be there today For the people of Lucknow, Lucknow University Although it is not specially designed for any All for a particular university Kids can see what they are seeing today You can also see tomorrow whatever you want to see tomorrow They are there today as well, go and see, it's okay Neither the number of questions nor the answers you need to answer

43:18 We will meet tomorrow at DDU This series of 50 questions is for evening At this time, kids, Peps, remember that Where does it happen? found in the stomach in the gastric juice that breaks down proteins It works for digestion. Tylin's If we talk about it, it is present in our saliva remains. Is it okay? and this is if trypsin If we talk about it then it is our small intestine It is found in. Speaking of vasopressin If we do this then it happens in our pituitary gland Is found. Now tell me which is the odd one out Is? In the stomach, saliva i.e. in our mouth there's one in the stomach, one in the intestine and In a pituitary gland. tell me which odd Is it forest? I made this very easy Question for you. tell me quickly From. Absolutely. In that too PYQs and

44:05 It will be about concepts brother. Mukund. At once You don't have to take tension. in yesterday's session will remain. Is it okay? Let us answer it now Give it to me quickly. Ok? CC is telling a lot Children. It is perfect. How did this odd one happen? Out? because it is released from the pituitary It is happening right? and in the pituitary gland Released from the posterior pituitary. pituitary another with vasopressin Produces hormones. This we people They are called pit vasopressin and oxytocin. Isn't it? The second hormone is oxytocin. Another name for vasopressin is kids remember Keep this in mind, it is also called ADH. It is also called antiboretic hormone

44:52 Is. Is it okay? so vasopressin is the Correct answer because all this is ours is present in the digestive system and Vasopressin is the only enzyme produced by the pituitary It is coming from the gland. Isn't it? Let's move on Are. Let's come to the next question. The next question is protoplasmic Where is the Grade of Organization found? Protoplasmic grade of organisation That means presence of only protoplasm. many times This also begs the question that protoplasm Who made the discovery? So remember that Not there? Discovery of Protoplasm The children were raised by Purkinji. Isn't it? this memory Keep it. ok pooja why confirm here Aren't you there brother? Isn't it? Please confirm. And Wherever do problems arise, children? Only If you go from here after asking questions With this you can clear the entrance exam with very good marks Let's go out. We just cannot say this.

45:38 You should read those topics also. Necessary This question will come. can come from this topic but there are lot of things in topic To form questions. So the kids just Don't ask questions. Always suggestions every time I will give you, asking questions is a good thing. Previous year questions should be asked. This is the best thing that happens. But its You have to read the topics also. Isn't it? So There would be vasopressin. Why would it happen? I told you. Let us go. Purkinje discovery of protoplasm It was done by. and protoplasm means very This is the basic level of organization. Periphera What is the level of organization in it? It is at the cellular level. what level It happens? Seller. That means the cells in their body has already been formed. anellido and If we talk about Mollusca, what do they contain? Is? These include organ system level Is. Organ system means proper body If we look inside then what is in their body

46:24 It is believed that a well developed circulatory system helps in improving your blood circulation. System, Digestive System, Respiratory system, excretory system, all these available Will go. Isn't it? now the protozoa which is this kids what is this? a type of protista It belongs to Kingdom Protista and its Proper cells etc. were not formed in the body There are. So we can call it this What type of organization will it be? protoplasmic is Nor about exam dates etc. Children, whenever you get dates, you will Will be informed. will keep getting updates To you. First of all you will get entry on our channel I will get it. It will come whenever. If not yet If I have got it then I will get it. Isn't it? still arrived Will not done. The most important among the 12 syllabus Children see the complete syllabus topics I have made the video. just recently It is uploaded. go check it out in the videos

47:11 do it. I have collected this from all the state universities. A syllabus has been designed for this. that syllabus Read it carefully. If we talk about 12th Look at evolution, if questions come up now then you I am not able to understand. See Evolution chapter It is important. Human Reproduction Chapter It is important. You saw human So many questions came from reproduction. So human reproduction is important. Apart from that, this chapter of yours is important Went. What? Human reproduction is done, Evolution has happened. Inheritance End Variation, the Molecular Basis of Inheritance and at the same time you Biotechnology and beyond If we do it then it is ecosystem and biodiversity. These There are some important chapters which will help you in 12th You must read it from here. Is it okay? Let go Move ahead. So protozoa is the correct answer will be. Let's move on to the next question. The next question is in the ecosystem Who are the producers? Bhai bada simple

47:58 This question has come. so in the ecosystem Who are the producers? Producers i.e. those who produce it first Produce some things. any longer Who comes under the ecosystem? Living organisms and non living Organisms too. Now Living Organisms like even a simple microorganism It is there, it is a plant, it is an animal, everything is there and In non living component like There's temperature in the atmosphere, there's sunlight, There is wind and there is soil. all these are non living Comes in components. All these are ecosystem It is kept in. now asking about these Who are the producers? So Producers please remember the kids that all these I am the producer, that is, the producer Those. So who produces Maine food? There are green plants, right? Plants are the which is the first way to produce food Let's work. ok this question once

48:43 It was asked that energy is transferred first Where does it start from? so many children answer I get it in writing from the producer. So kids Remember that the transfer of energy is It starts with sunlight because brother By absorbing the energy of sunlight, the plant Let's cook food. So many kids can do wrong Are. Can you talk to brother producer The energy starts traveling. So Remember, travel not with the producer This energy does it. Traveling by Sunlight It begins. Although this question Answer two will be given. Seconds, right? Not anymore Sorry, this will be an option, right? Yes yes. as many as Even the kids are giving the correct answer Is. Date based questions of Ecology come Are. Date based questions do not come quickly Are. Now what happened today kids? who today What day was it? Was there a day today? What's today? It is fifth, right? Yes. So it is June 5th. Today

49:28 Was there any day? So remember today the world It was Environment Day. Isn't it? So this from this Related questions come many times like this Which ones are related to date like base etc. Is it a special day? So remember the world It is Environment Day. So what day does this happen? It is celebrated on Fifth June. remember this Keep it. It's today, June 5th, right? Today's World It is Environment Day. Today you guys have to buy plants etcetera should be applied. Isn't it? Brother it's his The biggest decline is being seen Is. Due to this, different types of diseases occur. Let's go. Is it okay? Let's move on to the next question. Let's come to the next question. Next The question is through whom is malaria transmitted Is? Everybody knows about malaria here kids There is a disease which is here in your body When this disease occurs in your body

50:14 RBC count decreases very rapidly. Isn't it? And because of this you get shivers The shaver comes cold. chilly fever which is caused by a chemical Which we call hemozoin. Isn't it? Hemozoin is caused by chemicals. this then what happens when your rbcs start to drop Are? they begin to diminish, they rupture, They begin to shrink. So this chemical It is produced. With whom? your red blood From the cell. Isn't it? so asked the question here How is malaria transmitted? From the Culex mosquito. Culex recall Make sure that malaria is never transferred It is caused by this mosquito. would have been in Anpheles Is. Now you tell by mail in Enflees that From a female? Tell me quickly. big easy question This is it. good data not data base query data

51:00 Base question comes sometimes. Ok No? So you can also do database queries through the ecosystem You can read from the chapter. Biodiversity You will get it in me also. yes very good. All the children tell D in a line have been. It is perfect. D is the correct one Answer. Isn't it? Female Anopheles mosquito. D This is the correct answer. Let's move on to the next On the question. next question is Deoxygenated blood is present in which organ in our body? because of which does it flow or inside what does it flow does it? not because of whom but inside whom Does it flow? inside which of these Does deoxygenated blood flow? Option I have the renal artery, hepatic artery, Pulmonary artery, pulmonary vein. Now the children I told you this some time ago that What do renal, hepatic and pulmonary mean? It happens? I hope you are watching this session from the beginning

51:45 They already know these three terms You must have wondered what these three mean Is? Renal meant kidney, children. I told you guys that hepatic means liver And he told that pulmonary means lungs. Now Look, now there are three arteries here and one Wayne is written in this place. Now you will say that What type of blood is always present in the artery It happens? There is oxygenated blood. And you I will say that whatever vein is there is always There is deoxygenated blood. Now on that basis If we look at it, then the answer to our question is So it must be D. Pulmonary veins. But Remember one concept that is arterio vein If the word pulmonary is added before it then Because of this, this concept of it is It will be the opposite. means pulmonary artery if

52:32 If it is written then it will be deoxygenated blood. If there are pulmonary veins then they are oxygenated There will be blood. Now tell me about this concept what is the correct answer for this question Will you go? what is the answer of 24th question Will be done? Children 50 questions in today's We will discuss in the session. almost 50% Questions we have discussed so far today Are. Is No? Let's always look at the major arteries There is oxygenated blood. But pulmonary If it happens then it means there is deoxygenated blood in it will be. and gets attached to the veins in the pulmonary Meaning it will have oxygenated blood. Normal If there are veins then there is deoxygenated blood. Look now There are arteries at three places and a vein at one place. What Seems like? C Some children are telling. Hey, this one is perfect. yes then answer is c

53:17 It will happen. So pulmonary artery is the correct answer There is an answer. Isn't it? Pulmonary artery because Artery is only then the answer is oxygenated It happens. and the deoxygenated in question If asked, it would be pulmonary artery. Now understand Came? I understood the concept of this whole topic what is it? It will be C. yes hepatic and renal then It was meant to confuse. next question Come on pay. next question is which of the following is the first vertebra in the Mammals? In mammals, those in the variable column What is the first bone called? Are? He is asking this here. the first is Axis. The second one is written Atlas. wrote the third is perpendicular and the fourth one is written sacral. in a flash Tell me. These questions have been asked many times. In many state universities, this The question has been asked many times. so this Remember the question. Isn't it? times seconds vertebrae, sometimes even from the last vertebrae can ask questions. So keep this in mind. Here I am asking the name of the first vertebra

54:03 Is. tell me quickly From. No problem. The answer is wrong but it will be fine The mistake should not be repeated again and again. once wrong did it okay, did you find out whether the answer was correct If it happens then those mistakes should not be repeated because if it gets repeated then it will harm your The marks will fluctuate, children and You cannot repeat this mistake because You don't get a chance again and again. now if this chance If you miss this opportunity then you will get state Now for the university entrance exam Will get it next year. work hard for a whole year Will need it. So why not take it out at once let's go. Why not work hard for once? let's go. Is it or not? Come on brother, what will be the answer to this? yes, Its correct answer will be Atlas. as many as Even the kids are saying that it is absolutely correct. Correct answer of 25th will be available. Mounting Oh, on to the next question. Next the question is which part of the heart and

54:49 Do Mammals Work as Pacemakers? Which one is like that here There is a pay structure that works like a pacemaker does it? Okay, tell me. acts like a pacemaker who does? Look kids, that would be a pacemaker Is this where your heart beat is controlled? It happens. Actually it is our heart What category does this fall into? Myogenic I have a heart. Myogenic heart means one such Heart The impulse which is in it, the heartbeat, Produces Hart. This is somewhere else Production does not happen from this only. and its It starts on the left side of our heart From. Isn't it? From where? From the left side. this is it Our left atrium. this is the left Ventricle. this is the right atrium and this is Right ventricle. which is our left atrium It happens kids here on one side here

55:35 and the other place is the right atrium. so here But you will see that the right atrium is here But sideways it is located at this place SA Node. Isn't it? and move forward from here The AV node emerges from here. from the AV node The AV bundle is formed. and is formed by the AV bundle Purkinje fibers. And so when this The network grows and spreads throughout the heart if it gets distributed then because of that This is our heart beat, what is this? These Our heart beat could be controlled Is. Is it okay? So it is like this It gets distributed as well. so tell me here I am wondering who does a pacemaker? From where? Actually this heart beat is being produced Is. Bundle of his from such note to avy note Who do you call children? Bundle of His AV Another name for a bundle is. and the fourth is

56:20 Purkinje fibers. Meaning, the names of all four Are. Now you have to tell which of these is pacemaker Who is called? Many times in this Proper heart beat is not produced Is. So are artificial pacemakers are introduced. Let's go in a line an answer is coming Is. I am getting an answer from one line and It is coming out perfect. such node such full form anyone know? sino-arterial node I say it. Remember this too, children. Is No? So this is such a node. So the 26th The correct answer will be A. A is the correct Answer. Yes. All the kids are saying A It is perfect. Let's move on to the next question Pay. The next question is what is blood group Which of these blood groups does humans have? Who is a universal donor? That means this is Every person has his own blood group Can donate blood. well now it happens that

57:08 Every person of every blood group can donate blood to someone I can't even give it. take blood from anyone can't do it. The reason is that blood in special Antigens and antibodies are found. Correct Isn't it? and these are antigens and antibodies What do they do? others in our bodies If the blood type comes then it is ours Will clot the blood. It will coagulate. But there are two blood groups which are not One of them has such a blood group Someone who can donate blood to someone. And There is one who can receive blood from anyone Can. Sir who will I meet? Is it okay? So if we look here, what What is AB blood group called Is? This It is called universal acceptor. That means this Can receive blood from anyone. and o What is this blood group called? A

57:53 And I can't even receive blood from anyone And I cannot give it to anyone else. because It contains antigens and antibodies. Universal Why is this acceptor made? Because its No antibodies are found near them. many times He also asks this question that brother Avi Why is there a Universal Acceptor? So this too Remember this because brother what happens from here that these are like antibodies that's why here If there are no antibodies then it would be able to accept it

…
