Question

A bacterium divides every 35 minutes. If a culture containing 105 cells/ml is grown for 175 minutes, what will be the cell concentration per ml after 175 minutes?​

Answer 1

Therefore, total division would be: 17535=5 {This is the generation calculated}. After 35 minutes, the culture will have 2×105cells/mL{bacteria divides into 2 cells by binary fission}. Similarly, after 175 minutes (5 generations), the number of cells will be 25×105cells/mL which is,32×105 cells/mL.

HOPE IT HELPS YOU...

GOOD EVENING...
