Question

look where the arrow is pointing on the whale. what part of a bird is most similar to this part of the whale?
beak
wing
talons

Explanation:

The whale's flipper (the part the arrow is likely pointing to, as it's a common comparison in biology) and a bird's wing are both forelimbs. They are homologous structures, meaning they share a common evolutionary origin. While they have different functions (swimming for the whale, flying for the bird), their skeletal structures (like the presence of humerus, radius, ulna etc. in a generalized vertebrate forelimb plan) show this evolutionary relationship. The beak is a facial structure for feeding, talons are foot - related grasping structures, and a feather is an epidermal outgrowth. None of these (beak, talons, feather) have the same homologous forelimb relationship with the whale's flipper as the wing does.

Answer:

wing
