Final answer:
Cones do not enable vision in dim light; rods are responsible for vision in dim light conditions.
Step-by-step explanation:
False. Cones are photoreceptor cells in the retina of the human eye that are responsible for color vision and visual acuity in bright light conditions. They are sensitive to different wavelengths of light and allow us to perceive colors. However, cones cannot react to low-intensity light, and rods, another type of photoreceptor, are responsible for vision in dim light conditions. Rods can detect shades of gray and are much more sensitive to light than cones.
