Answer:

The patient’s eyes are too short.

Explanation:

A person can focus clearly on objects both near and far that means a person's vision is normal.

But when a person cannot focus clearly on objects both near and far then it means that the person is suffering from two defects.

(I) Long sight :

In this defect, the person cannot focus on the nearest object but he can focus clearly on distant objects.

Because his eyeball is too-short and the light is focused at a point behind the retina.

This defect can be correct by using convex lens.

(II) Short sight :

In this defect, the person cannot focus on the distant object but he can focus clearly on near objects.

Because his eyeball is too-long and the light is focused at a point front of retina.

This defect can be correct by using concave lens.

Hence, A doctor suggest converging lenses to correct a patient's vision.

Because The patient's eyes are too short.

1. A normal mammalian cell will shrink if it is placed into_________. (Assume all solutes are non-penetrating) A. pure water B.

GrogVix [38]

Answer:

B. 50 mM glucose; E. 300 mM glucose

Explanation:

In order for the cell to shrink the concentration of solutes in the blood should be above normal or higher than the intracellular concentration, so that water moves from the inside of the cell to the outside by the process known as osmosis.

The normal blood levels of NaCl = ~ 154 mM; therefore A, C and D will not cause any shrinkage.

The normal blood levels of glucose = ~ 3.9 to 7.1 mM; therefore water would move from the intracellular to the extracellular space since the solutes are 10x higher outside the cell, causing shrinkage of the cell.

How are red blood cells able to move through narrow vessels to carry oxygen throughout a multicellular organism? (1 point) a)The

geniusboy [140]

Answer:

The correct answer is - option B. They are small because they lack a nucleus.

Explanation:

Red blood cells or erythrocytes are specialized cell that produce in bone marrow and have specific role such as carrying oxygen from lungs to deliver it to the various organs and carry out carbon dioxide.

In mammals these cells lack cell organelles such as nucleus and mitochondria, a major factor that determined its smaller size. The size of RBC are move through narrow vessels throughout a organism because of its specific size and shape that provide it space for hemoglobin and allow to be flexible and bend to move through narrow vessels.

Thus, the correct answer is : option B. They are small because they lack a nucleus.
