Sweating and panting are examples of which characteristic of life?
Viktor [21]

Answer:

Responding to the environment

Explanation:

Sweating and panting are mechanisms of homeostasis i.e the regulation of the body's internal environment in response to changes or fluctuations in the external environment.

Sweating is a physiological response to the body's core temperature rising above the limit of 36.5-37.5°C. Once the hypothalamus in the brain detects this rise in temperature, cooling mechanisms are initiated. One of these is sweating. Release and subsequent evaporation of sweat through the sweat glands produces a cooling effect.

Panting is a physiological response more observed in dogs. Dogs lack sweat glands and therefore cannot lower their core temperature through sweating. Panting utilizes saliva instead of sweat to lower body's temperature to the set limit.
