In which situation can variation be most useful for a species?
Answer and explanation
Correct answer: When the environment changes suddenly
Variation is most valuable when environmental conditions change because individuals may differ in their ability to survive and reproduce. A particular inherited variation, such as better tolerance of heat or disease, may help some members survive and pass that trait onward. Thus option A is correct. Identical organisms have fewer alternatives, and no offspring means variations cannot be inherited by a new generation.
