If two organisms possess similar structures that serve similar functions but don't possess a common ancestor that shared that structure, then the structures are classified as
a. vestigial.
b. morphologies.
c. analogous.
d. homologous.

C. Analogous

Explanation:

For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying.

Analogous organ.

Explanation:

Analogous organ may be defined as the organs that have similar structure and function but not share a common function. This type of organ shows convergent evolution.

Analogous organs are opposite to the homologous organ. For example: Wings of bats, insects and birds have similar structure and function but does not have a common ancestor, they are analogous organ.

Thus, the correct answer is option (C).

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
