a. Energy of radiation lower than bond energies of organic molecules

b. Refractability of wavelengths through glassy media

c. Wavelengths short enough for reasonable image resolution

d. Speed of transmission through ocular mediums



2. Which component of the eye is most responsible for image formation on the retina? *

a. Iris

b. Lens

c. Vitreous Humor

d. Cornea



3-What types of cells in the retina constitute the beginning of our sensitivity to color?

a. Cone cells

b. Rod cells

c. Horizontal cells

d. Amacrine cells



4-What was the basic principle of neural function that Hartline discovered through his work with the horseshoe crab? *

a. Action potentials

b. Lateral inhibition

C. Winner takes all

D. Proportionality of intensity and neural transmission speed



5-Which animal uses mirrors, instead of lenses, to form images on the retina? *

a. Mantis shrimp

b. Octopus

c. Scallop

d. Cat



6-Roughly how much of the human brain is devoted to processing visual information?

a. 2%

b. 7%

c. 35%

d. 65%



7-In the human eye, why do the photoreceptors face the back of the eye rather than being pointed towards the light? *



a. An unfortunate evolutionary error

b. To protect them from direct light

c. To give them more space

d. To enable better debris removal and nutrient supply



8-If you are trying to see a dim star in the night sky, why might it be better to look slightly to the star's side rather than straight at it? *



a. Starlight can hurt the retina

b. There are more rods a little further away from the fovea
