A mammal maintains its body temperature at 37 °C. When the ambient temperature falls to 5 °C, the animal increases its metabolic heat production by 15 % above the basal rate. If the basal metabolic heat production is 100 kJ h⁻¹ and heat loss to the environment is proportional to the temperature difference with a constant of 2 kJ h⁻¹ °C⁻¹, determine whether the animal can maintain its body temperature under these conditions. Show the net heat balance.

Answer Options

A. No, net heat loss of 10 kJ/h
B. Yes, net heat gain of 60 kJ/h
Correct Answer C. Yes, net heat gain of 51 kJ/h
D. Yes, net heat gain of 45 kJ/h
Correct Answer
C
Correct Option:
Yes, net heat gain of 51 kJ/h
