1. Describe the pathway of light through the eye and the process of light refraction. 4 points Light enters through the cornea‚ which is the first step in refraction. The iris then modulates the amount of the light that enters the eye. The light then passes through the pupil‚ which regulates light entry into the inner eye and brings objects into focus. Light then then passes through the lens which focuses the light on the retina (made of rods and cones). The retina turns light into nerve impulses

As a part of my breakfast on Day 1‚ I ate a peanut butter and jelly sandwich. The creamy peanut butter provided both protein and fat for my diet while the multigrain bread provided me with carbohydrates.
