A small mammal has a body surface area of 0.09 m\(^{2}\) and a thermal conductance of 0.025 W m\(^{-2}\) °C\(^{-1}\). Its core temperature is normally 37 °C while the ambient temperature is 5 °C.\n\n(a) Calculate the minimum metabolic heat production (in watts) required to maintain the core temperature at 37 °C under these conditions.\n(b) If the animal can only produce 0.05 W of metabolic heat, what steady‑state body temperature (in °C) will be maintained? Give your answer to one decimal place.

A. 0.07 W; 26.5 °C

B. 0.8 W; 7.0 °C

C. 0.09 W; 28.0 °C

Correct Answer D. 0.072 W; 27.2 °C
