Brown bears pant, which means they breathe with short, quick breaths. This helps circulate cool air over moist surfaces in the mouth. What are brown bears doing as a result of panting?
Answer
A
maintaining body temperature by warming up
B
maintaining body temperature by cooling down
C
maintaining internal water levels by taking in moisture
D
maintaining internal water levels by releasing moisture
Explanation
Panting moves air over moist surfaces in the mouth, where some moisture evaporates. Evaporation removes heat from the body, helping the bear cool down and maintain its body temperature. So the correct choice is maintaining body temperature by cooling down.
