enot [183]

Answer:

C. All of the answer choices are correct.

Explanation:

Option A is correct because the reproduction of the cell implies arrangement of chromosomes, making of proteins, organelles, cytokinesis and other cells process that need energy since the mitochondria is not working properly there isn't an appropriate organelle function ( option B).

Option D is correct because ATP is needed for the membrane proteins to undergo active transport. For example the sodium-potassium pump is crucial for the balance of ions. With no energy the protein involved in this process would not work.

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,

Initial population

the initial population of bacteria - 2x 10³ per ml

So per liter, the bacterial population will be 2 x 10 ⁶

Generation time

1 generation time of bacteria is 30 min.

so 5 hours will have-   $\frac{300}{30}$ = 10 generations

New bacterial population

Using formula $2^{number of generation}$ 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.
