In summary, the cornea is the clear, transparent front covering which admits light and begins the refractive process. It also keeps foreign particles from entering the eye. The pupil is an adjustable opening that controls the intensity of light permitted to strike the lens.ight rays pass through a dense, transparent gel-like substance, called the vitreous that fills the globe of the eyeball and helps the eye hold its spherical shape. In a normal eye, the light rays come to a sharp focusing point on the retina. The retina functions much like the film in a camera.

Best Answer: A somatic cell is a simple body cell (not a Germ cell-aka gamate) so therefore in a normal human cell, you have 23 PAIRS of chromosomes in each cell-this is 46 chromosomes in total which are maintained through the process of mitosis in each cell cycle.
Best Answer: humans have 22 pairs of autosomes (44 chromosomes) and 1 pair of sex chromosomes ( 2 chromosomes). It all adds up to 23 pairs of chromosomes (46 chromosomes). Human somatic cells contain 22 pairs of autosomes and either two X chromosomes (in females) or an X and a Y chromosome (in males).
