Explain how myopia and hyperopia are related to the lens focusing on the retina.

liq [111]3 years ago

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.

Why would it be hard to find the CO2 level if the light intensity were very low? HELP!!!!
drek231 [11]
If CO2 was in very small amounts then it would be the limiting factor of photosynthesis, this means the process will take place at a much slower rate because it is lacking one of the raw materials it needs for the process to occur. To find the optimum light intensity you really need all other factors to be at optimum levels or in abundance.

Explain how the autoinducer molecule in luminescent bacteria signals when to luminesce
strojnjashka [21]

Autoinducer molecules are signalling molecules that need bacteria. In order for the autoinducer molecules to signal, the bacteria must find a way to initiate the signal and a way to respond to the signal it had created. Autoinducer molecules increase in production as the density of the bacteria cell increases.

Dominik [7]
<span>The correct answer is B. crepuscular activity. Crepuscular refers to animals and birds that are active at night, during twilight. So, these little birds don't usually travel large distances during the day, first of all, because they can't due to their small wings and plump bodies, and second of all, in order to avoid getting eating by a larger bird or animal. So they are usually nocturnal birds that live during the night.</span>
