The answer should be rectum.
2. To focus a microscope using the high power lens you must first in low power center the specimen and make sure it is in focus. Then switch to high power and adjust using the fine adjustment or the smaller knob.
3. It prevents dust from settling on the scope and in the lenses.
Answer:
A
Explanation:
I think this is the right answer? I'm not completely sure.
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.
Answer:
dimerization and phosphorylation
Explanation:
Protein kinase receptors are simply saying receptors with associated kinases (usually tyrosine kinases).
Protein kinases are enzymes that have the ability to modulate other enzymes (or some other proteins) by adding the phosphate group. This is known as phosphorilation process. As a result of structural change, protein can change its activity (phosphorilation usually increase the activity).
Such receptors are involved in a many processes within an organism that are important for the cellular growth, differentiation, metabolism .
