Osteoclast remove old bone while osteoblasts build new bone.

Osteoblast remove old bone while osteclasts build new bone.

Osteoclast deposit layers of compact bone while osteoblasts break down calcified matrix.

Osteoblast deposit spongy bone while osteoclasts break down compact bone.

Answer 1

A is correct..............

Answer 2

The correct answer is a.
Bone remodelling (or bone metabolism) is the term describing the continuous reshaping of the bones, by removing mature bone tissue and forming new bone tissue. Two main types of cells participate in this process, the osteoblasts and osteoclasts. Osteoblasts secrete new bone and osteoclasts break down the mature bone.
