Sound waves first move the eardrum, then the ossicles (hammer, anvil, stirrup), then move the hair cells
in the cochlea.

61. ANS: B
One of the ways the brain localizes sound is by determining which ear detects the sound first, since if the
sound is coming from the left of the person, the left ear will detect the sound first.

62. ANS: C
A sound from the left of us will reach the left ear first and more loudly than the sound wave that
eventually hits the right ear. This combination of clues helps the brain locate where sounds are coming
from.

75. ANS: C
Taste and smell are chemical senses, operating by absorbing chemicals from food that activate receptor
cells in the nose and tongue.

76. ANS: C
The olfactory cells process smells, like the smell of a gas leak. The retina and bipolar cells are involved
in vision and the cochlea is involved in hearing.

Taste and smell interact to produce flavor, so a head cold (which reduces the sense of smell because of
congestion) will also reduce the perception of the taste of food.
