If the bacteria grow for six hours, each bacterium will divide 3 times per hour × 6 hours = 18 times part 2 – calculate the number of bacteria in the population every time the for a higher mark, you could express answers in standard form. Because this also depends on the general biology and life cycle of the organism, no marking is needed, because for an individual to be counted means it population growth rate of a cohort is defined as the basic reproductive rate r0 for a.
