Question

1. which mechanism of reproductive isolation is illustrated by the differences in mating calls among frog species? a. temporal isolation b. behavioral isolation c. geographical isolation d. mechanical isolation 8. which isolation mechanism occurs when populations have different breeding seasons? a. mechanical isolation b. geographical isolation c. behavioral isolation d. temporal isolation 9. what happens during parapatric speciation? a. populations adapt to the same environment, leading to different traits b. two populations develop distinct mating preferences c. two populations inhabit different habitats with limited interbreeding d. a small subgroup becomes isolated and diverges from a larger population

Explanation:

• For question 7, mating - call differences are a form of behavior. Behavioral isolation occurs when species have different courtship or mating behaviors, so differences in frog mating calls illustrate behavioral isolation.
• For question 8, temporal isolation happens when populations have different breeding seasons, which is the key factor here.
• For question 9, in parapatric speciation, two populations inhabit different habitats within the same general area with limited interbreeding.

Answer:

1. b. Behavioral Isolation
2. d. Temporal Isolation
3. c. Two populations inhabit different habitats with limited interbreeding
