Light is registered in the retina when photos hit molecules of the pigment rhodopsin and change the molecules' shape. Even when they have not been struck by photos of light, rhodopsin molecules sometimes change shape because of normal molecular motion, thereby introducing error into the visual system. The amount of this molecular motion is directly proportional to the temperature of the retina.
Which of the following conclusions is most strongly supported by the information above?
A. The temperature of an animal's retina depends on the amount of light the retina is absorbing.
B. The visual systems of animal whose body temperature matches that of their surroundings are more error-prone in hot surroundings than in cold ones.
C. As the temperature of the retina rises, rhodopsin molecules react more slowly to being struck by photons.
D. Rhodopsin molecules are more sensitive to photons in animals whose retinas have large surface areas than in animals whose retinas have small surface areas.
E. Molecules of rhodopsin are the only pigment molecules that occur naturally in the retina.
OA is B
