A countercurrent heat exchanger enables an animal to _____. See Concept 40.3 (Page 883) A countercurrent heat exchanger enables an animal to _____. See Concept 40.3 (Page 883) increase heat loss by evaporation slow metabolism when food is not available produce more heat when needed reduce the loss of body heat to the environment absorb heat from the environment

Answer 1

reduce the loss of body heat to the environment

Step-by-step explanation:

• Convection is the heat loss by air or water moving across the skin surface.
• When exposed to cold air, cover exposed skin and take shelter from the wind.
• The thicker the insulating clothing layer, the better it prevents convection.
• Conduction is the direct contact with an object.
