Neco Model Questions Vol1 2022 Biology Question 29
Practice objective / multiple choice question 29 from the 2022 Neco Model Questions Vol1 Biology examination.
A bacterial culture is inoculated with \(5\times10^{5}\) cells mL\(^{-1}\). After 2 h the concentration rises to \(2\times10^{6}\) cells mL\(^{-1}\). Assuming exponential growth, determine its generation time in minutes. A second bacterial culture starts at \(1\times10^{6}\) cells mL\(^{-1}\) and after the same 2 h reaches \(8\times10^{6}\) cells mL\(^{-1}\). Which species has the shorter generation time and by how many minutes? State your answer as "second: 20 minutes shorter".
