Question

A single female frog can lay as many as 10,000 eggs in a breeding season, each egg carrying a unique combination of genes from its parents. Of these, all but a few are eaten or otherwise killed before reaching adulthood. How might laying so many eggs affect the long-term survival of the frogs should the environment change?
A. Since females can already lay large numbers of eggs, they would lay even more if the environment changed.
B. Many of the females would die if there were a change for the worse in the environment.
C. Changes in the environment would tend to favor the individuals with genetic combinations that made them bigger and more able to survive.
D. With so many genetic combinations, it is likely that a few individuals would have traits that would help them survive the changed environment.

Answer 1

The answer is D because this would help them to survive and is equal to natural selection
