Homework Answers
Rods are responsible for night vision.
Cones are associated with color vision.
Cones function in brighter lights.
The Retina contain two types of photo receptors rods and cones, the rods are more numerous (around 120 million) and are more sensitive than cones but they are not sensitive for color, the rods are more concentrated in the central yellow spot known as Macula. Cones contains color receptors and they are more concentrated in Fovea centralis where rods are absent. Fovea centralis is the spot of highest visual acuity or resolution in the eye.

The photoreceptors in the human eye, called rods and cones, have different sensitivities to different wavelengths of electromagnetic waves. (Figure 1) (Notice that the y axis in the figure is a logarithmic scale.) The rods, which number over 100 million, can only be activated by a certain range of wavelengths, but they do not pass any color information to the brain. In other words, they note differences in shades of grey (from black to white) and are responsible for a...

9. What statement about the cornea is INCORRECT? A. It mediates the majority of light refraction B. It refracts less light than the lens does C. It can be re-shaped by LASIK D. It has a refractive power of about 42 diopters E. It is positioned anterior to the lens 10. When comparing rod photoreceptors to cone photoreceptors, which statement is INCORRECT? A. Cones are responsible for daylight vision, whereas rods mediate night-time vision B. Cones are much more sensitive...

Looking at the results from the "Color Vision" experiment, which of the following is most likely true regarding the distribution of cones and rods in the retina? Question 1 options: You can see a shape before you can distinguish the color, which suggests that rods are more widely distributed on the retina than cones. Distinguishing blue at a wider angle than red or green, suggests that blue cones are more widely distributed on the retina than red or green cones....
