The optimal time to begin therapeutic exercise is usually during the A. proliferation phase B. inflamamtion phase C. early remodeling phase D. end of remodeling phase

B. proliferation phase

Explanation:

The proliferative phase is one of the stage of wound healing. This is a phase in which new tissues rebuilt over the injury to heal it. The tissues are made up of collagen.

In the proliferative phase the injury contracts and the skin becomes stiff, the muscles becomes rigid thus the body require optimal time to begin the therapeutic exercise. The exercise will improve the motion and flexibility of the body. The new network of blood vessels will cause the granulation of the tissues and provide sufficient nutrients and oxygen for recovery.

and after water is usually warmed by the sun the water temperature raises and then evaporates .

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
