It’s asking for the products of cellular respiration which are H2O,CO2
Mountain lions with lots of variation because variation is important for species’ survival. If there is an environmental change that negatively affects organisms with a certain trait, variation can insure that the entire species will not be wiped out because some organisms within that species might not have that trait and can survive.
Unify means to make or become united uniform, or whole.
(I personally don't agree that evolution is true; but here is my answer)
Evolution is a way Scientists like to theorize the world was made/ created. They try to explain why everything can about in a uniform way. Everything has a reason or theory. Even though scientists haven't been able to prove that Evolution actually exists, many people like the idea of it- just for the reason that it gives a more believable whole approach to how the Earth and Universe came about. For some people, it is more uniform than a religion.
I hope this helped you!
Answer:
A. It allows two populations to evolve separately.
Explanation:
Geographic isolation is theorized to have catalyzed the formation of new species. Let’s say groups A and B of a bird species get separated by something, and they can’t cross between to interbreed or exchange alleles.
We describe this as no gene flow, which is the opposite of choices C and D. Because of this, they may diverge if given enough time due to the difference in environmental pressures, because they’re now in different environments.
B is incorrect because it doesn’t apply.
