Based on the Information Presented in Your Textbook, Why Do

Based on the information presented in your textbook, why do you think that women might be at a higher risk of developing osteoporosis than men?

A) Because estrogen depletion is a causal factor in the development of osteoporosis, so when women experience a drop in estrogen it is a greater influence than for men.
B) Because women tend to exercise less than men, and a lack of weight-bearing exercise is related to the development of osteoporosis.
C) Because a deficit of calcium absorption is a major culprit in osteoporosis, and women tend to drink less milk than men, particularly during infancy, when bones are forming.
D) Because osteoporosis is a "primary X-delimited chromosomal" problem, and since women have two X chromosomes they have twice as much risk factor.
