Igcse Model Questions Vol1 2025 Biology Question 18
Practice objective / multiple choice question 18 from the 2025 Igcse Model Questions Vol1 Biology examination.
A small mammal has a surface area of \(0.02\;\text{m}^2\) and a thermal conductance of \(0.5\;\text{W·m}^{-2}\!·^\circ\text{C}^{-1}\). Its body temperature is \(37^\circ\text{C}\) while the ambient temperature is \(5^\circ\text{C}\). If its basal metabolic rate supplies \(0.20\;\text{W}\) of heat, calculate the additional metabolic heat (in watts, to two decimal places) that must be produced to maintain body temperature.
