adell [148]

The question is incomplete as it does not have the options which are:

a. The woman with stretch marks has a greater collagen-to-elastic fiber ratio.

b. The woman may have different gender babies.

c. The woman with less stretch marks has larger skin cells.

d. The woman without stretch marks has more cholesterol in her diet, which affects her cell membranes.

Answer:

The woman with stretch marks has a greater collagen-to-elastic fiber ratio.

Explanation:

The stretch marks on the hips, stomach and breast of pregnant women is a very common problem. These stretch marks appear pinkish in color which is very difficult to treat.

These stretch marks are the result of the collagen to elastin ratio which increases and stretches. This stretching happens due to the sudden or rapid increase in the weight of the body or the affected portion.

Thus, the selected option is correct.
