When a child breaks a bone, which of the following is responsible for rebuilding new bone tissue in the fracture while it heals?

a. osteoblasts
b. osteoclasts
c. osteoporosis
d. osteocytes

Option 'A' is correct.

Explanation:

When a child breaks a bone, Osteoblasts is responsible for rebuilding new bone tissue in the fracture while it heals.

Because Osteoblasts build new bone if  bones get broken somehow.

The new bone that built by Osteoblasts is known as "Osteoid", which is composed  of bone collagen and other protein.

They control mineral and calcium decomposition.

Osteoblasts are found on the surface of new bone.

Hence, Option 'A' is correct.

answer: wheres the options

explanation:

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
