Neco 2024 Biology Question 3
Practice objective / multiple choice question 3 from the 2024 Neco Biology examination.
An adult human has a basal heat loss of \(150\ \text{kcal\ h}^{-1}\) at thermal equilibrium. In a cold environment the body responds by (i) vasoconstriction, which reduces heat loss by \(30\%\), and (ii) shivering, which adds \(200\ \text{kcal\ h}^{-1}\) of heat production. Assuming basal metabolic heat production equals basal heat loss, calculate the net heat balance (in \(\text{kcal\ h}^{-1}\)) after these responses.
