Question

A bacterium divides every 35 minutes. If a culture
containing 105 cells per ml is grown for 175
minutes, what will be the cell concentration per ml
after 175 minutes?
(1) 35 x 10^5 cells
(3) 175 x 10^5 cells
(2) 32 x 10^5 cells
(4) 85 x 10^5 cells
plz someone answer
and don't give irrelevant answers or else I will report ur answers
I want answer alongwith proper explanation​

Answer 1

Answer:

is given that a bacterium divides every 35 minutes.

At 0 minutes, the culture contains 10

5

cells/ml

After 35 minutes, the culture will contain 2

1

x 10

5

cells /ml

Similarly, after 175 minutes, that is after 5 generations, the number of cells will be 2

5

x 10

5

cells/ml

This is equal to 32 x 10

5

cells/ml

Thus, the correct answer is '32 x 10

5

.'

Answer 2

Answer:

2)32×10^5cells

Explanation:

It is given that a bacterium divides every 35 minutes,

At 0 minutes, the culture contains 10

5

cells/ml.

After 35 minutes, the culture will contain 2

1

×10

5

cells / ml

similarly, after 175 minutes, that is after 5 generations, the no. of cells

=2

5

×10

5

cells/ml.

This is equal to 32×10

5

cell/ml
