And this question is asking us about Osma regulation and kangaroo rats and which of their listed upto adaptations is not one that can goods have. So a lot of adaptations do not make sense on this. You think about why evolutionarily they exist. Um, And to think about evolutionary, why the kangaroo nda wrapped may have made some of its at the adaptations. We have to think about the environment in which it lives. So can Crewe Brand slid in hot and to rye climates, so they need thio conserve water. All right. And so the way that they have learned to do so or they've adapted to do so is they have hyper tonic. You're This means they have minimal water, uh, minimal water loss. And then I like convoluted or highly complex maze of passages and then produced Dr Feces. Uh, because you actually you do not have a complete re absorption of water from the feces. Um, but kangaroo rats are really good at getting all of it out. And then long looks in the nef on and this is to ensure that the urine becomes as hyper tonic is possible. Um, so out of thes adaptations that the king roots of King Room rats have actually undergoing the thing that they can't do is secrete excess salt from their glands in their eyes. Just answer truth.
