everybody, this is Ricky and I&#x27;ll be walking through Problem number two from Chapter 36. In this question, we&#x27;re thinking, yeah, versus uric acid. And why is Yuri a better? All right, So Yuria and takes less energy to synthesize and also smaller, so it&#x27;s easier to be excreted. It is also less concentrated, meaning it will take longer before the molecule builds up to become talks. So if we look at our answer, choices would see that our answers, eh? Because Yuria takes less energy than you&#x27;re against to produce. I have. This video is helpful. I&#x27;ll see you in the next.

this question asks us, Teoh, basically compare your urea and uric acid as please call it&#x27;s. So let&#x27;s quickly review what we know about the forms of metabolic. Please, this question doesn&#x27;t cover it, but you should know that ammonia, in addition to your urea and uric acid, are the three forms in which metabolic wastes are excreted, the type of waste product produced and how the animal streets. It depends on the animals, evolutionary history and its habitat. Most aquatic animals dispose of their nitrogenous wastes as ammonia. This works for animals constantly surrounded by water, because even though ammonia is toxic, it can quickly diffuse across some membranes and be excreted across the whole body surface. Because it is so toxic, ammonia must be very dilute. Most terrestrial animals cannot afford to lose water, and the amounts necessary to retune routinely excrete ammonia. Instead, many animals convert ammonia in tow, less toxic compounds which could be stored in the body. The disadvantage of converting ammonia is that the animal must end energy doing this. The less toxic compounds can be Yuria or uric acid. Our job now is to look more carefully at the differences between these two we know that your area is water soluble, which I&#x27;ll just put like a little water drop there to help us remember that. Uh, okay. Yuria is water soluble and uric acid is water insoluble. Because of this, Yuria is excreted in water and uric acid is not diluted in water. Instead, uric acid is secreted as a semi solid paste. There&#x27;s a higher energy cost to making uric acid, but this could be balanced by the great savings in body water and wheat. So let&#x27;s work through the answer options for this question and pick which one makes the most sense. So first, they say your acid is a simpler molecule than Yuria. Well, I drew the structures here just so that we can really look at ourselves. But we can see that obviously that is not true. So house, Alright, second choice. It takes less energy to make uric acid. So this is also false. Um, the there is an advantage to having uric acid instead of Yuria, and that is that it doesn&#x27;t need to be dissolved in water. But turning Yuria into uric acid has a pretty high energy cost so we can eliminate that one Let&#x27;s jump down to option D. More Salyut czar removed excreting uric acid and urea. So the process of removing Saul Utes, um, his independent of whether you used Rhea or uric acid. Right now we&#x27;re talking about water recovery. Not so you to exchange. So we know that this is not the fact. Answer, and then option C less water is required. Teoh excrete uric acid. So this is exactly right. Um, so we choose Option C as the crack dancer.

So this question is asking us about how various organisms get rid of their nitrogenous waste. So we have several answer choices. B says that mammals never excretes there nitrogenous waste in the form of uric acid. Now this. You should always really careful with statements that say never. Because there&#x27;s it&#x27;s very hard to create absolute rules like that and C says by marine fishes, in mostly the form of Yuria. That&#x27;s not true. We can see here that fish usually excrete their nitrogenous waste in the form of ammonia. Ammonia is pretty toxic, which means that you need to dilute it with a lot of water if you want to safely excrete it. So fish are really lucky in that they live in a very watery environment, so they&#x27;re able to have enough water to X treat their nitrogenous waste in the form of ammonia without causing it to be in concentrations that could be toxic to the organism. So, no, that is incorrect because fishes use ammonia, not Yuria and D says that this does not contribute to the ah similarity of the urine. That doesn&#x27;t make any sense because we have a salute. Of course, it&#x27;s going to contribute to the Ah similarity. And finally, E says, requires more water if the waste product is the rather insoluble uric acid. Now uric acid is used by birds, and it&#x27;s pretty paste like and it&#x27;s insoluble. That is true, but it doesn&#x27;t require more water. Actually, the reason that they&#x27;re adapted to use uric acid is because it requires less water and birds need to be flying around. And water is very heavy that can&#x27;t be carrying around a bunch of water. So uric acid is the best way to go for birds because it uses less water, not more. So that is also incorrect. And so, by process of elimination, we know that the answer has to be a by humans can be in the form of Yuria and uric acid.

Sam Limsuwannarot · Answer

the question here basically asked which of these is correct? So eight years basically states that your gas is produced from the breakdown of amino acids. This is not going to be correct. This is because uric acid is produced from a breakdown of nuclear acids. Sit there for dancing eight here.

Rikhil Makwana · Answer

everyone, this is Ricky. And today I&#x27;m gonna watch you through a couple other teams. And this is a question on excretion. So how do humans get rid of the nitrogenous waste by excreting your and this happens in booth. Other hand excrete nitrogenous waste through your IQ. Ask it. Yeah, Differences. Yuria has more, is more soluble or is the greatest liability water and then you&#x27;re in acid, which is almost so helpful.

Sam Limsuwannarot · Answer

So the question here basically asked during of a healthy person. A healthy person contains what? So we know that you&#x27;re in humans are gonna basically to create one of three forms of the nitrogenous waste that all animals produced, which are uric acid Yuria on ammonia. So humans we know produce Yuria, which is not as unlike witty, but it&#x27;s not that solid. So the answer to the question is going to be be.
