Answer:
Option-A
Explanation:
A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.
The bacterial cell grows by the exponential function that is by x initial population of bacteria.
In the given question,
<u>Initial population</u>
the initial population of bacteria - 2x 10³ per ml
So per liter, the bacterial population will be 2 x 10 ⁶
<u>Generation time</u>
1 generation time of bacteria is 30 min.
so 5 hours will have- <u> </u>= 10 generations
<u>New bacterial population</u>
Using formula<u> </u> x initial population of bacteria
x (2 x 10⁶)
= 1048 x (2 x 10⁶)
2048 x 10⁶
Thus, Option-A is the correct answer.
