Waec Model Questions Vol1 2020 Biology Question 4
Practice objective / multiple choice question 4 from the 2020 Waec Model Questions Vol1 Biology examination.
A small mammal has a basal metabolic rate that generates 5 kJ of heat per hour. Heat is lost by convection at a rate of 0.8 kJ h⁻¹ °C⁻¹ multiplied by the temperature difference between body (38 °C) and ambient (10 °C), and by evaporative cooling at 0.5 kJ per gram of water evaporated. The animal can evaporate up to 2 g of water per hour. Determine whether the animal can maintain its body temperature under these conditions, and if not, calculate the heat deficit per hour (kJ).
