Step 1
The question asks about color vision. Let's examine each option: * **is interpreted in the cerebellum:** The cerebellum is primarily involved in motor control and coordination, not visual processing. This is incorrect. * **depends on the amount of available Show more…

11. When you exit a dark room into a brightly lit environment, within seconds, you to see a crisp view of your surroundings. However, when you enter a dark room from a brightly lit environment, your eyes might take more than 10 minutes to become used to the new surroundings. Your eyes are waiting for A. the rods to begin to function B. the cones to begin to function C. the pupils to get smaller 12. Which of the following descriptions of photoreceptors in the eye is not correct? A. Rods are sensitive to light and register black and white. Cones detect colours. B. Rods are concentrated in the fovea of the retina and function well in dim light. C. Rods are concentrated at the periphery and function well in dim light. D. Cones are concentrated in the fovea of the retina and function to detect colours. 13. Colour blindness can result from the loss of specific types of cones, or it can occur in individuals having fewer cones of a given type. An individual has 50% less than the normal number of green cone photoreceptors in his or her retina. How would this affect his or her vision? A. This person has a mild green colour blindness. He or she cannot see green colours very clearly and has difficulty distinguishing colours involving green hues. B. This person will have difficulty adapting to varying light levels. His or her cone receptors take much longer to adapt in a brightly lit area. C. This person does not have a colour blindness because no green cone photoreceptors are in the retina; only red, yellow, and blue photoreceptors exist. D. This person has night blindness. He or she should start to eat more carrots to replenish the stock of retinal molecules in the retina.

In the dark, why is colour vision lacking? Cones have a low sensitivity Cones are tonic receptors that adapt slowly Neural adaptation limits information processing Reduced visual pigments are more sensitive to colour Pupillary dilation causes less light to be focused on the fovea
Madhur L.
Which of the following about rods is true? They are: 1) most concentrated at the fovea centralis 2) are mechanoreceptors 3) are defective in color blindness 4) most concentrated at the optic disk 5) functioning in night vision
