Neco Model Questions Vol1 2023 Biology Question 31
Practice objective / multiple choice question 31 from the 2023 Neco Model Questions Vol1 Biology examination.
During a rise in ambient temperature, the hypothalamus initiates two responses: sweating and cutaneous vasodilation. The cooling effect of sweating is \(0.5^{\circ}\text{C}\) per minute, but high humidity (80 % relative humidity) reduces its effectiveness by 20 %. Vasodilation increases heat loss by \(0.2^{\circ}\text{C}\) per minute. Simultaneously, basal metabolic heat production adds \(0.1^{\circ}\text{C}\) per minute to core temperature. If the core temperature rises to \(38^{\circ}\text{C}\) while the set point is \(37^{\circ}\text{C}\), how many minutes will be required for the core temperature to return to the set point, assuming the responses continue until the set point is reached?
