Question

question
which of the following statements is correct?
answer
in older adults, osteoblast activity exceeds that of osteoclast activity.
in young adults, the rate of bone deposition is greater than the rate of bone resorption.
bone remodeling involves the simultaneous process of bone resorption and bone deposition.
osteoblasts and osteoclasts are active during the growth years only.
i dont know yet

Explanation:

Bone remodeling is a continuous process throughout life that involves the simultaneous action of osteoclasts (which break down bone - resorption) and osteoblasts (which build bone - deposition). In older adults, osteoclast activity often exceeds osteoblast activity leading to bone loss. In young adults, bone deposition and resorption are in a dynamic equilibrium, not necessarily with deposition always greater. Osteoblasts and osteoclasts are active throughout life, not just during growth years.

Answer:

C. Bone remodeling involves the simultaneous process of bone resorption and bone deposition.
