Gce Model Questions Vol1 2025 Biology Question 39
Practice objective / multiple choice question 39 from the 2025 Gce Model Questions Vol1 Biology examination.
At rest a human body produces metabolic heat at a rate of 80 W. Heat loss to the environment occurs by convection and radiation and is proportional to the temperature difference between the body core (\(T\)) and the ambient air (20 °C), described by \(\text{Loss}=k\,(T-20)\) with \(k=5\ \text{W °C}^{-1}\). Under normal conditions the body temperature stabilises when heat production equals heat loss. During a fever the hypothalamic set‑point rises to 39 °C, causing metabolic heat production to increase by 10 %. Assuming the proportional loss law still applies, calculate the new equilibrium core temperature (in °C) during the fever. Give your answer to one decimal place.
