Question

During adolescence, the mass and girth of the bones increases. Which of these could be the appropriate justification for this?
A) Both osteoblasts and osteoclasts are equally functional.
B) Osteoclasts are more functional than osteoblasts.
C) Osteoblasts are more functional than osteoclasts.

Answer 1

C
Osteoblasts form bones, osteoclasts destroy bones. So, yeah.

Answer 2

Answer:

Option (C).

Explanation:

Osteoblasts and osteoclasts are two major types of cells present in bones.  Osteoblasts are defined as bone-forming cells that help in bone mineralization. On the other hand, osteoclasts are are responsible for bone resorption and cause breakdown of bones.

So, during adolescence, girth and mass of the bones increase as osteoblasts are more functional than osteoclasts at this stage.

Thus, the correct answer is option (C).
