Answer:

In myopia the image is focused ahead of the retina. While in Hyperopia the image is focused beyond or behind the retina.

Explanation:

I'll start by defining the two key terms, Myopia and Hyperopia. Myopia is otherwise called short-sightedness. It is a condition where one cannot see the images of objects located far away from the eyes and tend to see images within a short distance from the eyes. Hyperopia on the otherhand is otherwise known as long-sightedness. It is an eye defect which manifests by one not seeing objects close to the eyes instead he or she see only objects far from the eyes. These two eye defects are a malfunction of the accomodation feature of the eye.

Normally when an object is viewed all the parts of the eye (the organ for vision) function to focus the image of that object on the retina but especially on a part of it called the *light spot*. This then translates the image to the brain using the optical nerve. The brain then interpretes what is being viewed

However in Myopia, images are focused ahead of the retina . This is as a result of the eyeball being too long in relation to the focusing power of the cornea and eye lens.

In Hyperopia on the other hand, images are focused behind the retina. This is by the diameter of the eye being too short or the cornea being too flat.

In conclusion, from the above stated points,it is glaring that Myopia and Hyperopia affect the lens's ability to focus images on the retina.

The process of ____________ increases genetic variability as it produces gametes for sexual reproduction.
otez555 [7]
The phrase to fit into the blank is "sexual reproduction"!
In sexual reproduction each of the parents produces a gamete and contributes to half of the  offspring's genes. This means that the offspring is a unique composition of the two parents.

In contrast, in a asexual reproduction, the offspring would likely have the same genetic code as the parent.
