Question 1

As the eye adjusts to focus on a near object, the cornea must change shape because the lens is unable to.

Accepted Answer

The lens, not the cornea, changes shape to focus on near objects. The lens becomes thicker to increase its refractive power, a process known as accommodation.

Question 2

The otolithic membrane functions in hearing and in maintaining equilibrium.

Accepted Answer

The otolithic membrane functions in maintaining equilibrium by detecting linear accelerations and head tilts, but it does not play a direct role in hearing; that function is primarily served by the cochlea in the inner ear.

Question 3

Olfactory receptor cells are modified bipolar neurons that bear olfactory hairs.

Accepted Answer

Olfactory receptor cells are indeed modified bipolar neurons that have olfactory hairs called cilia, which have binding sites for odor molecules.

Question 4

The refractive indices between glass and oil are quite similar, as compared to the refractive indices between glass and air, which are quite different. Therefore, in which of the following situations will light bend the most?
A) When passing between glass and air
B) When passing between glass and oil

Accepted Answer

Light bends more when there is a greater difference in refractive indices between two media. Since the refractive indices between glass and air are quite different, light will bend more when passing between glass and air compared to glass and oil.

Question 5

Select all that light must pass through on its way to being focused on the retina.
A) Cornea
B) Aqueous humor
C) Lens
D) Choroid
E) Sclera

Accepted Answer

Light must pass through the cornea, aqueous humor, and lens on its way to being focused on the retina.

Question 6

The bending of light as it passes through to different media (such as glass vs. water) is referred to as ________.

Accepted Answer

The answer of The bending of light as it passes...
