Waec Model Questions Vol1 2023 Biology Question 42
Practice objective / multiple choice question 42 from the 2023 Waec Model Questions Vol1 Biology examination.
A person's basal metabolic heat production is 100 W. When exposed to a cold environment (5 °C) the body shivers, raising heat production by 15 %. Heat loss to the environment follows Newton's law: rate = k (T_body - T_env). Initially the heat‑loss coefficient k is 5 W °C⁻¹, but vasoconstriction later reduces k by 20 %. Assuming steady‑state conditions after vasoconstriction, what is the body temperature (°C) at that stage?
