Answer:
I'm thinking maybe B, illustrates the principle of natural selection.
Explanation:
This example shows that, once a particular event happens in a species' ecosystem that negatively affects their lifestyle, natural selection occurs and kills off those with a disadvantageous adaptation (in this case the narrow-beaked finches, since they could no longer eat insects but did not have the beak size to crack seeds), allowing those with the advantageous adaptation (in this case, the thicker-beaked birds) to prosper.

Answer:
The structural components of the nervous system enables it to carry out the following functions:
1). collect information about changes in the organism's environment (both internal and external).
2). process the information; and
3). act up on the information.
The nervous system carries out its functions efficiently and extremely rapidly since information and instructions speed as electric impulses along nerve from one part of the body to another almost instantaneously.
The basic structural unit of the nervous system is the nerve cell or neurone which consists of a dense cell body and protoplasmic processes collectively known as nerve fibre.
