You are given a 1 liter bacterial culture in exponential stage of growth. The generation time of the bacteria is known to be 30
nydimaria [60]

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 2^{number of generation} 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>\frac{300}{30}= 10 generations

<u>New bacterial population</u>

Using formula<u>  </u>2^{number of generation} x initial population of bacteria

2^{10} x (2 x 10⁶)

= 1048 x (2 x 10⁶)

2048 x 10⁶

Thus, Option-A is the correct answer.

With ideal environmental factors, the reproduction rate of bacteria is...
Artist 52 [7]

With ideal environmental factors, bacteria are able to reproduce at a very rapid pace.

<h3>Bacterial reproduction</h3>

Bacteria reproduce mainly by a single cell dividing into two, given the right condition. In order words, they reproduced by binary fission.

When environmental conditions are optimum, a typical bacterial cell can divide every 4 to 20 minutes depending on the species.

The time can become longer with sub-optimal environmental conditions.
