Question

1. a females risk for osteoporosis increases significantly _________.

○ after the start of her menstrual cycle
○ when she lifts weights
○ after she experiences a pregnancy
○ after menopause

Explanation:

Osteoporosis is a condition where bones become weak and brittle. After menopause, a woman's estrogen levels drop significantly. Estrogen plays a crucial role in maintaining bone density. With lower estrogen, bone resorption (breakdown) outpaces bone formation, leading to a decrease in bone mass. Starting of menstrual cycle is associated with increased estrogen (which is good for bone health). Lifting weights is a weight - bearing exercise that is beneficial for bone health as it stimulates bone formation. Pregnancy, while it has some physiological changes, is not a significant risk factor for osteoporosis compared to menopause.

Answer:

after menopause
