WebCount Rate = (2206 ± 21) counts/mm. It is interesting to see what would happen if instead of counting five one-minute periods we had counted the total 5 minutes without We would have then observed a total of 11028 counts. constitutes a sample of n= 1. The mean count rate for 5 minutes is thus 11208 and the error on this, = 11208 = 106. To WebThe key concept of exponential growth is that the population growth rate —the number of organisms added in each generation—increases as the population gets larger. And the results can be dramatic: after 1 1 day ( 24 24 cycles of division), our bacterial population would have grown from 1000 1000 to over 16 16 billion!
