The answer to this question is A (Because Earth rotates on its axis.)
Answer AND Explanation:
The variations that Darwin regarded as raw materials for the process of evolution have been traced to changes that occur at the gene level or the chromosome and these changes are called mutations. Organisms with beneficial mutations are able to pass them on to their offspring during reproduction. Transmission of such mutations through many generations could lead to the emergence of new species. The emergence of new species requires a long time and is also affected by the rate of mutations that a particular species undergoes. This leads to evolution.
The genes they occur in by listing each one's: • normal
I would say: Tropical Rain Forest, Tropical Dry Forest,Tropical Savanna Desert, Temperate Grassland, Shrubland Temperature, Forest Northwestern Coniferous, Forest Boreal, Forest Tundra..etc.
Good luck!
