D) rhodopsin.
E) duplexity.

Question

Quizplus · Accepted Answer

The photopic system is responsible for color vision. It is composed of cone photoreceptors that are sensitive to different wavelengths of light and can distinguish between colors. Rods are responsible for vision in low light conditions, but cannot differentiate colors. The scotopic system refers to vision in low light and is primarily mediated by rods. Rhodopsin is a pigment found in rods that is important for low light vision. Duplexity refers to the fact that the retina contains both rod and cone photoreceptors, which allow for both low light and color vision. However, the question asks specifically about color vision, which is only mediated by the photopic system.
