Which of the following statements are true concerning the eye? the far point of the normal eye is infinity. astigmatism refers to a defect in which the surface of the cornea is not spherical. instead, it is more sharply curved in one plane than another. farsightedness can be corrected with a diverging lens. nearsightedness can be corrected with a diverging lens. the hyperopic eye focuses rays from an object at infinity in front of the retina; the myopic eye focuses rays from an object at infinity behind the retina.

The far point of the normal eye is infinity

Astigmatism refers to a defect in which the surface of the cornea is not spherical. Instead, it is more sharply curved in one plane than another.

Nearsightedness can be corrected with a diverging lens

Explanation:

A normal eye has its far point (at infinity) and its near point (about 25cm in front of the eye).

Astigmatism is an eye imperfection which refers to the curvature of the cornea or lens. This vision condition is characterized by the irregularly shape of the cornea or lens (not equally curved  in all directions). As a consequence, refractive error occurs  which appears as nearsightedness (myopia-inability  to focus on distant objects) or

farsightedness (hyperopia-inability to focus on nearby objects).

the answer would be d

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
