Gce Model Questions Vol1 2025 Biology Question 22
Practice objective / multiple choice question 22 from the 2025 Gce Model Questions Vol1 Biology examination.
An animal produces metabolic heat at a rate of \(200\ \text{kJ h}^{-1}\). It can dissipate heat by sweating (efficiency \(0.7\ \text{kJ g}^{-1}\)) and by panting (efficiency \(0.5\ \text{kJ g}^{-1}\)). High ambient humidity reduces the efficiency of both mechanisms by 20 %. The animal may lose up to \(1.5\ \text{L}\) of water per hour without risking dehydration. What is the minimum volume of water the animal must lose per hour to maintain thermal balance under the humid conditions?
