A single bacterium is actively growing in a medium that supports its growth to a number of 100 million. Assuming the division time of the bacterium as 3 hours and the life span of non-dividing bacteria as 5 hours, which ONE of the following represents the maximum number of bacteria that would be present at the end of 15 hour ?

A

10

B

64

C

24

D

32

Text Solution

Verified by Experts

The correct Answer is:
D
Time `=(15)/(3)=5` times division occur. No. of bacteria `=2^(5)=32`
