Question

1. which specialized structure do nocturnal primates use to see better at night?

○ a tapetum lucidum
○ a tooth comb
○ a fused jaw
○ a grooming claw

Explanation:

Nocturnal primates rely on the tapetum lucidum, a reflective layer behind the retina, to enhance low-light vision by reflecting unused light back through the photoreceptors. The other options serve non-visual functions: a tooth comb is for grooming/feeding, a fused jaw aids structural support, and a grooming claw is for grooming.

Answer:

a. a tapetum lucidum
