B) Osteopetrosis
C) Osteomalacia
D) Multiple myeloma

Answer 1

Osteoporosis is a disease characterized by a decrease in bone mass and weakened bones that easily fracture. It is different from osteopetrosis, which causes increased bone density. Osteoporosis commonly occurs in older adults and causes bones to become brittle and break easily.

Step-by-step explanation:

Osteoporosis is a disease characterized by a decrease in bone mass that occurs when the rate of bone resorption exceeds the rate of bone formation, resulting in weakened bones that easily fracture. It is a disorder that generally occurs in older adults, causing bones to lose minerals, become brittle, and break easily. Osteoporosis is different from osteopetrosis, which is a condition where there is increased bone density due to inability to resorb bone.
