Gce Model Questions Vol1 2019 Biology Question 20
Practice objective / multiple choice question 20 from the 2019 Gce Model Questions Vol1 Biology examination.
A bacterial culture starts with \(1.0\times10^{6}\) cells. Under optimal conditions the generation time is 30 min, so the population doubles every 30 min. After 5 h the culture is exposed to an antibiotic that increases the effective generation time to 90 min, but the cells continue to grow exponentially. Assuming no cell death, calculate the total number of cells present after 10 h from the start of the experiment.
