8 What is the function of rods? Dim light/peripheral vision Light regulation Eye lubrication Color vision Multiple Choice 5 points This is the opening in the eye and can be dilated: Pupil Iris Sclera Cornea Multiple Choice 5 points

## Step 1<br />The first question is about the function of rods in the human eye. Rods are a type of photoreceptor cell in the retina of the eye. They are responsible for vision in low light conditions and for peripheral vision. They do not contribute to color vision, which is the function of the other type of photoreceptor cell, the cones.<br /><br />## Step 2<br />The second question is about the part of the eye that can be dilated. The pupil is the opening in the eye that can be dilated or constricted. The iris is the colored part of the eye that controls the size of the pupil, but it is not the opening itself. The sclera is the white part of the eye, and the cornea is the clear front surface of the eye. Neither of these can be dilated.
