Use the following information to answer the question(s) below.

Two populations of birds with somewhat different coloration live on opposite sides of a peninsula. The habitat between the populations is not suitable for these birds. When birds from the two populations are brought together, they produce young whose appearance is intermediate between the two parents. These offspring will breed with each other or with birds from either parent population, and all offspring of these pairings appear intermediate to various degrees.

1) What keeps the two populations separate?

A) temporal reproductive isolation

B) lack of hybrid viability

C) behavioral reproductive isolation

D) habitat isolation

C

Explanation:

Behavioural reproductive Isolation. This is the type of behaviour isolation that do not allow some members of a population to mate with the others. It might be due to how they find and choose mates. Some species have very unique rituals and behavior that has to take place before reproduction can occur so most of the time it is a form of pretty-zygotic barrier that happens before reproduction can happen.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
