Which of these is most responsible for "light adaptation"--the process by which we only gradually become able to see objects in a brightly lit place after being in the dark?
A. Cone receptors are very hyperpolarized in the dark, and they must be exposed to bright light for awhile before they will depolarize. B. Rhodopsin is quickly inactivated in the presence of bright light so rods become unresponsive, and the higher-acuity cones then become the main detectors of vision. C. Because rods are more sensitive to light than cones, they gradually become extremely activated in bright light. D. Cones and rods are stimulated equally, leading to difficulties in interpreting the sensory inputs to the brain. E. Rhodopsin is not activated by colored light, and the lack of stimulation causes rods to gradually depolarize when we are exposed to bright light.
