5. Sarit is at a bar full of music, chatter, and laughter. He gets involved in an interesting conversation with a woman named Mona, and he tunes out all the background noise. Sarit's friend, Karen, taps him on the shoulder and asks what song just played on the jukebox.

A. binocular disparity B. bottom-up processing C. oculomotor convergence D. top-down processing

A. binocular disparity

B. night

30. Why are olfaction and gustation called chemical senses? A. Neither one has sensory receptors that respond to molecules in the food we eat or in the air we breathe. B. Because they are unrelated to biological senses. C. They have sensory receptors that respond to molecules in the food we eat or in the air we breathe. D. We cannot use these senses without the presence of specific chemicals in the body.
