Should a sensible retina have more foveas (or larger ones, perhaps) or might peripheral retina be more than leftover real estate?
Answer:
Eye is a sensory organ of vision, which enables us to see the objects. In humans, two eyes are situated in the orbital cavity of the skull, the eye balls of the eye are supported by a number of accessory structures.
Eye ball is a three layered structure, the outer layer is cornea, the middle layer includes, choroid, ciliary body and iris, the inner nervous coat contains, retina.
Rods and cones: These are functional components of the eye. It is illustrated that sensible retina have more foveas or larger ones because cones are predominantly located densely in the center of the retina of eye and this area is referred as “fovea” here it is profoundly found that there are no presence of rods because the area outside the fovea centralis is peripheral retina and it has more rods. These rods are more sensitive to incident light compared to sensitivity of cones.
Mechanism of ight involves the following steps:

1. why might a protein have multiple domains. 2.why a protein might be comprised of more than one chain. 3.why a protein structure might show gaps when the real protein has none. 4.why a protein might bind nucleic acids. 5.why a protein might have disulfide bonds. 6. are ligands important for function or just artifacts of the structure process? 7. Why would the surface of a membrane-bound protein have a different polarity from a soluble one?
