Step 1
Which statement describes responses to a decrease in body temperature of a mammal?
Answer
When a mammal experiences a decrease in body temperature, it typically responds by initiating vasoconstriction. This process narrows the blood vessels, reducing blood flow to the skin and extremities, which helps conserve body heat. Additionally, the metabolic rate tends to increase as the body aims to generate more internal heat to counteract the temperature drop. Therefore, the correct response is option C: Vasoconstriction and an increase in metabolic rate.
