a fracture or dislocation. It is a kind of irritation of tissues and protective
response to injury and fracture; muscle spasm may displace a nondisplaced
fracture or prevent it from reducing spontaneously.
The answer is D, sweating.
Homeostasis is where the body uses some mechanisms to maintain a optimum condition for the body to function. These conditions may include body temperature, blood glucose level etc.
Sweating is a mechanism that can help maintain the body temperature. During hot conditions, the sweat glands under the skin surface may produce sweat, which is then released to the skin surface. When the sweat is on the skin surface, they evaporate. During evaporation, heat energy is brought away from the skin as the sweat molecules that have a higher kinetic energy (=temperature) escaped from the sweat drop. The average temperature of the sweat is reduced.
Eventually, the temperature of the body is decreased and this help maintain the suitable temperature for the body to function.
Therefore, your answer is D, sweating.
