Explanation / Answer

1) The answer is 3. Doubling time of all the listed organism is as follows:-

Bacillus megaterium - 25 min

Staphylococcus aureus- 27- 30 min

Lactobacillus acidophilus- 66- 87 min

Mycobacterium tuberculosis- 792- 932 min

2) The answer is 3. Generation or doubling time is the period required for an organism to doubling its population. Escherichia coli generally doubles in 20-25 mins if appropriate growth conditions are provided.

3) The answer is 2. Exponential phase is also called log phase as the growth of bacteria follows geometric progression i.e. 20,21,22,23,24.......2n (where n is the number of generation).
