What conclusion would be most appropriate about the genetic variation between humans and the three apes as illustrated by the phylogenetic tree? a) genetic variation between all four organisms is non-existent. b) the genetic variation between all four organisms is about the same. c) the genetic variation between humans and orangutans is the greatest. d) humans branched off from the other three animals due to great genetic variations.

The genetic variation between humans and orangutans is the greatest.

Explanation:

Humans and orangutans are farthest from each other in the tree, indicating the greatest biomolecular differences or genetic variations. The branches tell us that there are genetic differences; we cannot say from the tree that the amount of differences are equal.

i think that d. wind is the answer.   i missed the question when i answered a. currents.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
