The observation that different geographical areas sometimes exhibit plant and animal communities of similar appearance, even tho
ugh the individual plants and animals are not closely related, is called A. the fossil record.B. homology.C. convergent evolution.D. divergent evolution.E. adaptation.
Convergent evolution is a type of pattern of evolution which occurs when the two unrelated species evolves with the same feature or traits as a result of the exposure of the species to the same environmental conditions.
This type of evolution results in ion the formation of the analogous structure which is functionally similar but is evolved from the same ancestor.
In the given question, since the two unrelated species: plants and animals exhibit the same appearance on different geographical areas thus represents that convergent evolution is taking place.
Thus, C) convergent evolution is the correct answer.
We require to keep our water supply clean because we imbibe that water. If our water supply wasn't unsullied, we would die of dehydration. Another reason is that without water, all the crops would die and we wouldn't have any aliment to victual and so we would withal die of hunger.
