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.
Answer:
Independent Variable:
temperature
dependent variable:
chirps
Hypothesis:
the lower the temperatures the less chirps
constants:
temperature or food and water
repeated trails:
success and failure
control:the experiment
The species that has the same predators as species c would benefit the most
The answer is B. they embody the idea of descent with modification.
