electromagnetic radiation
photoreceptors
wavelengths
4. The three-color theory suggests, the retina contains ________________. (1 point)

5. If you have normal color vision, you are a _______________. (1 point)
6. The retina, which consists of three layers of neurons (photoreceptor, bipolar and ganglion), is responsible for detecting the light from these images and then causing impulses to be sent to the brain along the ____________. (1 point)

8. Given your knowledge about genetics and heredity, answer the following question about color-blindness.
A woman gives birth to a set of fraternal twins: a girl and a boy. She also passes on a color-blindness gene. Which of the children is more likely to be color-blind? (1 point)
the girl is more likely to be color-blind from birth
the boy is more likely to be color-blind from birth
the girl will never be color-blind because the gene came from her mother

9. Like other stimuli, odors can spontaneously evoke _____________. (1 point)
fatigue and nausea
the taste buds

10. One day, you accidentally touch a hot stove. Given your knowledge about how information is processed in the body, which of the following is the best description of how you might perceive “pain?” (1 point)
Information about “heat” would be collected and processed by the central nervous system
Information about “heat” would be collected and processed by the peripheral nervous system
Information about “heat” would be collected by the central nervous system and transmitted to the peripheral nervous system. The peripheral nervous system would then interpret that information and send a response back to the central nervous system
Information about “heat” would be collected through your fingertips and transmitted by the peripheral nervous system to the parietal lobe of the central nervous system. The central nervous system would then interpret that information and send a response back to the peripheral nervous system
