E) There are short-wavelength cones and long-wavelength cones.

Question

Quizplus · Accepted Answer

The duplicity theory of vision suggests that there are two types of photoreceptors, cones and rods, in the retina that are responsible for different aspects of vision. Cones are responsible for high-resolution, color vision in well-lit environments, while rods are responsible for low-resolution vision in dim light. This theory proposes that a single type of receptor system cannot produce both high sensitivity and high resolution, thus requiring the use of two different types of photoreceptors.
