Answer 1

Answer:

The answer is B: Haplorhines have better color vision.

Explanation:

Haplorhines are known as dry-nosed while Strepsirhines are known as wet-nosed.  Haplorhines and Strepsirhines are two different kind of primates but they have different characteristics such as variation of the brain size, because Haplorhines have bigger brain than Strepsirhines, Haplorhines do not have the enzyme in charge of producing Vitamin C while Strepsirhines have it. Haplorhines have a more developed vision than Strepsirhines. In this sense, Haplorhines possess a layer called tapetum lacidum which allows them to see at night when the light is low, while Haplorhines do not possess tapetum lacidum but, they have something called fovea, which help the to see during the day and have a vision color which is not a feature of Strepsirhines.
