d. pernicious anemia.

Answer 1

Osteoporosis is the disorder associated with calcium and vitamin D deficiencies, estrogen depletion, and lack of exercise in old age, leading to decreased bone density and increased fracture risk.

Step-by-step explanation:

The disorder of old age that is associated with calcium and vitamin D deficiencies, estrogen depletion, and lack of exercise is osteoporosis. Osteoporosis is characterized by the decalcification of bones due to a calcium deficiency in the diet, hypoparathyroidism, and a low vitamin D content in the body.

Factors contributing to osteoporosis include poor diet, smoking, alcohol consumption, and lack of exercise, which are all involved in bone resorption. The condition leads to weaker, brittle bones that are more susceptible to fractures, even with minimal or no stress.

Additionally, hormonal changes such as a decrease in estrogen may impair the normal deposition of new bone by osteoblasts.

In essence, osteoporosis is a bone disease associated with decreased bone density and skeletal weakness, making fractures more likely to occur in older adults.
