Which of the following characterizes the eyes of nocturnal mammals?

Question

Quizplus · Accepted Answer

Nocturnal mammals have a higher percentage of rod cells than cone cells in their retina, which allows for better vision in low light conditions. Rod cells are more sensitive to low light levels and are better able to detect movement, while cone cells are responsible for color vision and function better in bright light.

Answer: D
 Nocturnal mammals have small pupils at low light levels, which allows them to control the amount of light entering their eyes and therefore improve visual acuity in low light conditions. In bright light, their pupils dilate to allow more light to enter the eye.

Thus, options A and D characterize the eyes of nocturnal mammals.
