Answer:
Skin,muscles and metabolism play a significant role in maintaining his body temperature
Explanation:
Role of skin
In cold environment the blood vessels of the skin constrict to prevent the loss or liberation of heat from his(jim) body.
Role of muscles
The one of principle function of muscle is to store glycogen.The stored glycogen of jim"s muscle undergo glycogenolysis to generate heat inside his body.
Role of metabolism
