In the human eye, the greatest amount of refraction occurs when the light passes from the air into the
a. iris
b. cornea
c. lens
d. aqueous humor
e. vitreous humor

The correct answer is B. In the human eye, the greatest amount of refraction occurs when the light passes from the air into the cornea.

Explanation:

The ocular refraction refers to the refraction that occurs in the light coming from the objects when crossing the different parts of the eye, causing the images to concentrate on the retina.

When the light rays, after crossing the cornea and the lens, are projected on the retina at a single point creating a clear image that is transmitted to the brain for processing, we talk about normal refraction.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
