Mechanical stress applied to bone increases osteoblast activity in bone tissue, and the removal of mechanical stress decreases osteoblast activity.
Explanation:
Osteoblasts are cells , that are produced in the bone marrow and are responsible for formation of bones and bone matrix.
Whenever a mechanical stress is applied on the bones , a series of reactions are triggered. As a result the activities of osteoblast increases to synthesize more and more bone matrix to provide strength.
Again on the other hand a decrease in mechanical causes a decrease in the activities of the osteoblasts.
Okay, this has to be in your own words, but I will tell you this. Natural Selection is living organisms that have adapted to the environment which surrounds them leading the the producing of offspring. Example, bugs are eaten by frogs and frogs are eaten by snakes and snakes are eaten by birds.
