Answer:
C
Explanation:
Volcanic activity spews greenhouse gases, such as carbon dioxide, into the atmosphere. These gases reduce albedo because they do not allow particular wavelengths of light to escape into space after hitting the earth’s surface. This is how they cause global warming that results in climate change.
The answer is no, they are just two varieties of the same species adapted to different environment.
The change in moth color was caused by natural selection which favored the color more suitable for a certain conditions. Thus, in dark background, dark-colored moths could camouflage and escape from the predator (birds). So their chances for the survival and reproduction were higher than those of light-colored moths. When the pollution was reduced, the light colored moths were beneficial for survival.
So, the conclusion is that changes in the environment caused changes in the characteristics that were most beneficial for survival.
