Question

Summarize the hypotheses that explain variation in human skin color as adaptations to variation in UV radiation.

Accepted Answer

Hey everyone. Let's take a look at this question together. UV radiation can degrade blank which is essential for fetal development and sperm a genesis. Let's recall what we've learned about the process of fetal development as well as sperm a genesis. To try to figure out which of the following is essential for those processes and to try to figure out which of the following can be degraded by you radiation. Looking at our answer choices here, we can see that there is one option here that we know is essential for fetal development and sperm A genesis and that is answer choice B folate or folic acid. And so we know that the role that folate plays in sperm A genesis is that it deletes De Deans. And these key genes are those that are involved in the folate metabolic pathway. So full late metabolism. And we also know that when it comes to fetal development, folate or in that case folic acid is actually responsible for forming the neural tube, which we know that the neural tube is responsible for forming the early brain as well as the spine. And so that means it is essential for fetal development and so full it can be degraded by that UV radiation. And so answer choice B is the correct answer. I hope you found this video to be helpful. Thank you and goodbye
