Which describes farsightedness? check all that apply.
distant objects are blurry. nearby objects are blurry.
objects appear larger when wearing corrective glasses.
objects appear smaller when wearing corrective glasses.
convex lenses can correct it.
concave lenses can correct it.

Option B - Objects appear larger when wearing corrective glasses

Option D - Convex lenses can correct it

Explanation:

Farsightedness is a problem in which a person is able to view far away objects clearly but is unable to view nearby objects.  

A convex lens is used to correct farsightedness. The focal point lie behind the retina of eyes as the distance between the retina and eyepiece is very small , thus to correct this convex lens is used which reduces the focal length.  

A convex lens magnifies an object and make it larger than its normal size thus the nearby object which was not visible earlier is now easily visible.  

Thus, both option B and D are correct.

"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."
