Given that frogs are nearsighted in air, which statement is most likely to be true about their vision in water? (a) They are even more nearsighted; because water has a higher index of refraction than air, a frog’s ability to focus light increases in water. (b) They are less nearsighted, because the cornea is less effective at refracting light in water than in air. (c) Their vision is no different, because only structures that are internal to the eye can affect the eye’s ability to focus. (d) The images projected on the retina are no longer inverted, because the eye in water functions as a diverging lens rather than a converging lens.

Which statement is accurate about the cochlear duct? a. It detects linear acceleration of the head when the otolithic membrane bends the hair cells. b. It is filled with perilymph. c.

We have three types of cones in the retina. Explain how we can see a large range of colors with only three types of cones:
A. Describe the development of color vision. Why is this a significant development in mammal evolution? B. What are the differences between the two types of animal eyes?
Most animals lack cones in their retinas. How, then, do such animals view the visual world?
