Question 1

Select the statement below that is not true with regards to the process of light adaptation.
◦ Rhodopsin is uncoupled from light transduction.
◦ Visual acuity is diminished.
◦ Retinal sensitivity decreases.
◦ The activity of rods is reduced by rapid bleaching of rhodopsin.

Question 2

Humans can see several thousand shades of color but have cone photoreceptors that are sensitive to only three (perhaps four) wavelengths of light. What is the best explanation for why we see so many colors?
◦ Shades of color are purely psychological and learned by association with age, infants only seeing in black and white.
◦ Color perception is dependent on the millions of rods as well as cone photoreceptors.
◦ Colors are added and enhanced in the primary visual cortex of the brain.
◦ Color perception is achieved by activation of various combinations between the three cone types.

Did you know?

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).

Dietary intake of approximately double the recommended daily amount of vitamin A, by women, has been shown to reduce bone mineral density and increase the chances for hip fractures compared with women who consumed the recommended daily amount (or less) of vitamin A.
