Igcse Model Questions Vol1 2017 Biology Question 10
Practice objective / multiple choice question 10 from the 2017 Igcse Model Questions Vol1 Biology examination.
Two bacterial species, A and B, are cultured at \(37^{\circ}\text{C}\). Both start from an inoculum of \(2.0 \times 10^{5}\) cells. After 2 hours the populations are \(1.6 \times 10^{6}\) cells for species A and \(2.0 \times 10^{6}\) cells for species B. Assuming exponential growth, determine which species has the shorter generation time and calculate that generation time in minutes (round to the nearest whole minute). Give your answer in the form "Species X, Y minutes".
