Waec Model Questions Vol1 2025 Biology Question 39
Practice objective / multiple choice question 39 from the 2025 Waec Model Questions Vol1 Biology examination.
A resting adult produces metabolic heat at a constant rate of 80 W. Heat is lost to the environment according to L = k (T_core - T_ambient), where k is the heat‑loss coefficient (W °C⁻¹). With an ambient temperature of 20 °C and k = 5 W °C⁻¹, what is the steady‑state core temperature? If vasodilation reduces the heat‑loss coefficient to 3 W °C⁻¹ while the metabolic heat production remains unchanged, what is the new steady‑state core temperature? Give both temperatures to one decimal place.
