Which statement about compound eyes is true?a. They do not contain a lens or lenslike structure.b. They cannot sense color.c. They have from 1 to 10 ommatidia.d. They are found in insects and also many vertebrates.e. They probably have less resolving power thansingle-lens eyes.
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.
The transduction process of converting light into neural signals sent to the central nervous system involves which of these steps? A. Bipolar Cells collect signals from Rods and Cones. B.

Light that reaches the eyes passes first through the Retina which focuses that light onto the Cornea.
