本站收录: 2026-05-22

[00:00:00]If your target in NEET Biology is 360 out of 360 then this video is for you.

[00:00:06]This is the legendary HMS. HMS stands for The Hand Picked Mock Series. I started this before NEET where I make students solve the most expected questions which touch the heart directly. Ok? So be sure to check out this playlist. Apart from this, I also have Legendary Quarter for you here on this channel in which I have done PYQs of last 10 years and have done complete exemplar. Now listen to the rules of this video. This is only for serious NEET aspirants. You have to pause on every question and use your brain first. I have to try it myself. Only then can we move forward.

[00:00:34]After that listen to my answer and my logic.

[00:00:35]Write your answers somewhere and then keep ticking or crossing them. And at the end of the video you will see your score like in this video I will make you do 14 questions.

[00:00:43]You have to leave your score in the comments at the end of the video.

[00:00:47]That is the rule. Ok? Let us begin. Look friend, let's all start. Not everyone reaches the end. Let's see which one you are. So let's start with the first question. You pause and try yours, brother. Very comfortably.

[00:00:58]I am explaining myself. You try it. The first question considers the following features. Organ System Level of Organization Butler True Coelom with Segmentation. Which one is right for everyone? Look, recap this simple funda in your mind.

[00:01:10]If I talk about segmentation, then in which does it appear? You talk about Annelida, Arthropoda, Chordata, AAC. So now if we go by AC then Mulska is gone, Mulska is gone, Mulska is gone. So the correct answer is option fourth. Let's see. That is your final answer. The rest is common to all.

[00:01:23]Ok? Look, if something goes wrong, let it happen, but stay till the end and learn something. Let's move on to the next question. The next question is that I have two graphs drawn here.

[00:01:31]Reaction one and reaction two. Ok? I want to tell you which one is right for the forest. You try it yourself by doing your pose. If a mistake happens, let it happen. Try it yourself. Let me explain. Look, if you compare number one and number two, then in both the energy is released through exothermic reactions. Why? This is my substrate level. This is the level of the product. Substrate level. Then the energy is being released. Which one is releasing more? More releases are happening in the first one.

[00:01:54]Secondly, compare the energy of activation of both. Energy of activation is more in one compared to two.

[00:02:00]So the energy of activation is higher, which means it will be slower. So one will be slower and more egogonic than reaction two.

[00:02:07]Option four is your correct answer. Let's see.

[00:02:09]That is correct. will proceed. Very nice question. There are four Coptiles here in front of you.

[00:02:14]Setup for the part of an start of an experiment. Which of the following will bend towards the light source? Look, it's a simple concept. If we cut it, it is never going to bend. I blew up the TP.

[00:02:27]I will not be able to see its auxin effect. So he was eliminated.

[00:02:29]Eliminated. Now left 2 3 and left 3 4 okay? So 1 minute. I also eliminated this one wrongly. Sorry. Yes.

[00:02:38]Both of them got eliminated. What is left with me now? 1 4 or I have 3 4 so number four will be guaranteed. Because when light is coming from here, all the oxygen will accumulate here and it will bend like this.

[00:02:50]In case number three also it will bend towards the light.

[00:02:52]Understand the matter because it has been asked to bend towards the light source because the oxygen will accumulate here and it will bend like this because we are cutting this side in it, so all the oxygen will remain here, so there will be no bending towards the light. So the correct answer is option fourth that is three and four and that is your final answer. Ok? You must have read that we call this phototropic curvature and oxygen runs away from light.

[00:03:14]Like in a normal case, if such oxygen is spread here and if you turn on the light from this side, then all the oxygen will get divided and accumulate somewhere, it will accumulate on this side. So this is the same thing.

[00:03:25]I wore the heel on one side and not on the other side, otherwise I would bend the side where I am wearing the heel upwards. So this will keep bending more and more like this. Is it okay? Let's move on to the next question. Take a pause and try.

[00:03:37]Read the following statements. And which of these are completely incorrect?

[00:03:41]Give it a try. You try your best to use your brain. Let's read it. The first statement is proteins are heteropolymers type of biomolecule. That's correct. Essential amino acids are those which are supplied in our body through. That's absolutely correct. Essential is what we take from outside. Non- essentials are not needed. These cells after water carbohydrates from se na na proteins. Lipids are not strictly macromolecules. There is a mistake in this too. Let me give you a task. This is your task.

[00:04:07]What's wrong with that? Think and tell me. The next mistake was made for illumination which is present in some plants which is heteropolymer. So, C, D and E are wrong in this. Mention D's mistake separately with a time stamp.

[00:04:19]What is the mistake? Not strictly micro molecules is correct. Is there any other mistake? Think, understand and tell. Correct answer will go to option second. That is I have three Rs incorrect. C, D and E. Let's see next.

[00:04:30]By the way you should be on my Telegram for all regular updates. Ok? And all, look, I conduct a class daily on Unacademy app at 6:00 pm.

[00:04:39]That's the Darwin series mock tests that you must attempt. You should not be skipping them at all.

[00:04:43]Next question take a pause and try.

[00:04:48]Do it through option elimination. Watch the appearance of Chiasma. Chiasma will develop in leptotene, zygotene, pachytene, and diplotene. Let's search.

[00:04:55]Diplotene went wrong in number five.

[00:04:57]Diplotene, diplotene gone wrong. So the first one is eliminated. The third one is eliminated.

[00:05:02]Which I removed. Let's match next.

[00:05:04]Next is the terminalization of chiasma. Should be in diakinesis and where else did the option go? Did I eliminate the wrong one? Stop it brother. Stop. This was to eliminate it from Diplotin. Yes.

[00:05:17]After that, the Turnalization of Kayzo should be my diakinesis. Both have beans. It made no difference. Formation of bivalent or tetrad compounds occurs in the zygotin.

[00:05:24]This went wrong. And let's see.

[00:05:26]Appearance of recumbent packets. Exactly third is my correct answer. It was a simple factual but it should be known.

[00:05:32]Your recap is done. The next question is how many ATP are produced by the complete oxidation of two molecules of isocitrate by ETS only? You are bringing isocitrate. Meaning you're going through the entire Krebs cycle once. Now when you go through the Krebs cycle once, you get A 3 NADH2. One FADH2 is obtained. I'm removing GTP and ATP for now because I should have ETS. Now how much NADH2 do I have? Will give 3 * 3 = 9 ATP.

[00:05:57]And how much is a FADH2? will give me two ATPs.

[00:05:59]How much did I get in total? I saw a gain of 11 ATP.

[00:06:02]Right? Now understand the math of these 11 ATPs.

[00:06:05]I am getting 11 from one bicycle. That means 11 ATP are being obtained from one molecule of isocitrate.

[00:06:11]Right? So how much is there from two molecules?

[00:06:12]22. That is my correct answer. So, whoever remembers the sheet of a crap bicycle, it can definitely be made from it. Ok? Hey, there is a problem, right?

[00:06:18]I have uploaded the balance sheet video on this channel, you can watch it. Next, take your time, take a pause and try.

[00:06:25]When light is made to split into its spectral components and then use it to illuminate Cladophora aerobic bacteria accumulate mainly in the region of red and blue light. This is absolutely correct that plants absorb red and blue light, this is also correct but it is wrong that only light is absorbed by others also, yes activity is seen more here, so now my assertion is reason A means assertion correct reason correct and explaining B means assertion correct reason correct not explaining C means assertion correct reason false and D means assertion false acceptable. Ok? So Reese is wrong on this one. The assertion is correct. The correct answer will come in option third. Will go with That Is C. Let's see next. Take a pause and try. Feeding and breathing is simultaneously possible in humans.

[00:07:08]What is it? Not possible. If you try, you will face problems brother. Meaning the food will go on the wrong path.

[00:07:13]Negative Pressure Breathing Accuracies in Humans. Meaning, you understand negative pressure, right? We first expand our volume, drop the pressure, then the air rushes in.

[00:07:22]So statement two is correct and one is wrong. Is there any option that matches it?

[00:07:26]Meaning okay? Well, there is some controversy here and there in some PYQs.

[00:07:30]But look, what is the simple funda which is conceptually correct.

[00:07:33]You will have to pause one momentarily otherwise there will be a problem. Ok? So let's move on to the next question. Take a pause and try it yourself once. So you keep trying by doing your pose.

[00:07:42]What is the first statement saying?

[00:07:44]Which of the following is the most true statement about endocrine? Ok? Let's see in addition to some other organs GIT, kidney, heart. That's absolutely correct. The pituitary has two major parts.

[00:07:55]Collectively secrete six trophic hormones. Collectively secrete six trophic hormones. Doesn't it seem like a slightly controversial statement?

[00:08:03]If I talk about six trophic hormones, I will have a separate pars distalis.

[00:08:07]I have two different hormones near the pars nervosa.

[00:08:10]Dice C statement. Next Pineal Gland Melatonin Important Diurnal Rhythm. That's absolutely correct. PTH calcium home is increasing not decreasing.

[00:08:20]So what will you put in it? The most correct nun will then go into it. Let's do one thing.

[00:08:26]In this, review the NCERT wording once. Because there are technical errors in the statement. Ok? If the book has written the exact language of six then you will consider two as correct and put one.

[00:08:36]Otherwise we will go for nun. Ok? So once just go a double check with NCERT line here. Ok? So let's just move on to the next question.

[00:08:43]You should check this one on the NCERT line and post it separately in the comments.

[00:08:46]Under which of the following growth conditions maximum expression of lac operon is expected? Now if I talk about maximum expression then shine the logic. Think about it once. Look, the lac operon needs lactose. Now the lactose will break down and after breaking down lactose we get glucose plus galactose.

[00:09:05]If I increase the amount of glucose galactose.

[00:09:07]Meaning the lactose was broken down too much.

[00:09:09]Now if I want maximum activity then I need high level of lactose. You must have read the basic principle of low level of glucose.

[00:09:17]Cross link it somewhere from there and your work will be done.

[00:09:19]So you will end up with high lactose and low glucose.

[00:09:21]Option one is the correct one. Next is an E. coli with a mutated Z gene. Cannot grow in medium containing only lactose at the source. Why so?

[00:09:34]Understand the reason. Because it has a mutated Z gene.

[00:09:37]So PIP O Z V Z makes my beta galactosidase. Now because I have Z, you see, when such long questions come, then first recall your concept in your mind.

[00:09:46]It's variant then mistakes won't happen.

[00:09:48]So Z makes beta galactosidase.

[00:09:51]Now what will happen in this matter? Because it will not be able to produce beta galactosidase.

[00:09:54]So it will not be able to survive. Option two is your correct answer. Next, how many codons should be present in the translation unit of a processed mRNA if it codes for a protein containing 99 amino acids?

[00:10:06]What would you do? Think about it. Look, the funda is very simple.

[00:10:10]I need one codon for one amino acid.

[00:10:12]So 99 amino acids require 99 codons. Wrong answer.

[00:10:17]If I take a simple example of 99 from Let's, what I take are three amino acids.

[00:10:22]So codon one, codon two, codon these three amino acids are formed but you also need a stop codon. So including that always remember 99 codons for 99 amino acids plus one stop codon correct answer is my what? Option one is 100, that is the minimum number required. Next repeated use of drugs increases the tolerance level of receptors in our body. Addiction occurs as receptors respond only to high doses.

[00:10:48]Absolutely correct, isn't it? Understand the logic.

[00:10:50]Example: You get beaten at home every day. Ok? You get immune to getting beaten every day, then one or two slaps make little difference.

[00:10:56]Because repeated beatings increase your tolerance. Ok?

[00:11:00]What is the next statement? Addiction Acres S Receptor Respond. Now it is obvious that one or two slaps are normal for you.

[00:11:08]You won't feel the wind unless you push harder. Same story here also that a person consumed a little alcohol. For the first time, a little alcohol had more effect. Then its capacity kept increasing. What does he care now? If he is not feeling any difference from taking lettuce on his own for some x amount then his dose will keep increasing because he needs a kick.

[00:11:26]Why do people get addicted to these drugs? People Just to Be Fancy.

[00:11:31]It's very wrong. Ok? But people try to become fancy. Isn't it? So what happens again due to repeated use is that the body starts responding to higher doses. The person becomes an addict. So what will be the correct answer in this? Assertion is right in its place, reason is right in its place. I am not explaining.

[00:11:44]So you will leave with B. Next is Factual. The match is The Following. Look, ithios means fish. Soro means lizard reptile.

[00:11:52]So Ithiosaurus are fish-like reptiles. Make A into four. Eliminate oh oh oh oh oh it got done too quickly.

[00:12:00]Formed by single matching. Now friend, what is your score out of 14? Let me know in the comments. Complete the task given to you.

[00:12:05]Ensure you are connected on my Twitter plus you should be part of these special classes that I take on a regular basis on the Unacademy app.
