Pls help everyone is using me for points if you use me for points I'll report (;

OH LOL I DID THIS IN 7TH GRADE

Explanation:

so if i remember when the trees where white the pepper moths that where white survived more often that the black ones, then when the industrial war came the trees where covered in ash, so the white moths survived

MY SENTENCE

It shows how a change in an environment can effect a species natural selection, for example the white moths survived more than the black moths so the reproduced while the black moths where eaten by predator's, then when the environment changed and favored the black moths they survived and reproduced while the white moth got picked off by predators.

Hope this helped mate :>

The correct answer will be option-A.

Explanation:

The gradualism and punctuated equilibrium are the mechanisms which explain the process of evolution of species through speciation or the formation of species.  

Both the concepts explain the rate of changes that take place in a population as the process of gradualism explains the slow rate of speciation while punctuated equilibrium explains the sudden rate of evolutionary changes taking place in any population.

Thus, option-A is the correct answer.
