the hormone that increases cell division in growing bones is:
growth hormone
thyroxine
parathyroid hormone
insulin

question 15
1 pts
which of the following is correct of the female pelvis when comparing it with the male pelvis:
the female iliac bones are less flared
the distance between the female ischial spines is greater
the distance between the female ischial tuberosities is less
the angle of the female pubic arch is smaller
the female pelvis as a whole is deeper, and the bones are heavier and thicker

Explanation:

Question 14

To determine the hormone that increases cell division in growing bones, we analyze each option:

• Growth hormone: Stimulates cell division and growth in bones (and other tissues).
• Thyroxine: Regulates metabolism, not primarily for bone cell division.
• Parathyroid hormone: Regulates calcium levels, not bone cell division.
• Insulin: Regulates blood sugar, not bone growth.

So growth hormone is the correct answer.

To find the correct statement about the female pelvis vs male pelvis:

• Female iliac bones: More flared (not less), so first option wrong.
• Distance between ischial spines: Greater in females (correct, as female pelvis is adapted for childbirth, wider space).
• Distance between ischial tuberosities: Greater in females (not less), so third option wrong.
• Pubic arch angle: Larger in females (not smaller), so fourth option wrong.
• Female pelvis: Shallower, bones lighter/thinner (not deeper/heavier), so fifth option wrong.

Thus, the correct option is the one about ischial spines distance.

Answer:

A. growth hormone
