Question

if an animal behavior increases ________, the behavior is more likely to become common in the population. choose the best answer.
a diversity
b fitness
c incidence of death
d all of the above

Explanation:

In the context of animal behavior and evolution, fitness (biological fitness) refers to an organism's ability to survive and reproduce. A behavior that increases fitness (e.g., better foraging, avoiding predators) will be favored by natural selection and become more common. Increasing diversity doesn't directly relate to a behavior becoming common (it's about variety), and increasing the incidence of death would be detrimental. So the correct answer is related to fitness.

Answer:

b. fitness
