Question

Quizplus · Accepted Answer

The ability to detect movement on the left side indicates peripheral vision, which is best served by rods. Rods are more sensitive to low-level light and are located about 20 degrees from the center of the retina, outside the area of the macula where cones, responsible for color vision, are concentrated. Therefore, options A and B are incorrect. Option D refers to hair cells in the cochlea, which are not relevant to vision.
