Neco Model Questions Vol1 2023 Biology Question 11
Practice objective / multiple choice question 11 from the 2023 Neco Model Questions Vol1 Biology examination.
A desert rodent has a cylindrical body of length \(12\ \text{cm}\) and radius \(2\ \text{cm}\). Its thin fur reduces heat loss by \(30\%\). A desert jackrabbit has a spherical body of radius \(8\ \text{cm}\) and its large ears increase heat loss by \(20\%\) per unit ear surface area. Both animals experience the same ambient temperature difference of \(15^{\circ}\text{C}\). The basic heat loss per unit surface area is \(k = 0.5\ \text{J s}^{-1}\text{cm}^{-2}\,^{\circ}\text{C}^{-1}\). Assuming heat loss is given by \(Q = k \times \text{SA} \times \Delta T\) and adjusting for the fur or ear effects, which animal loses more heat per second? Show all calculations.
