Question

Approximately how many bacteria may be obtained from one bacterium in an hour?

Answer 1

Answer:

Hii CutiePie

If the bacteria grow for six hours, each bacterium will divide 3 times per hour × 6 hours = 18 times. Every time the bacteria reproduce, the number doubles. To calculate the number of bacteria at the end of the growth period, you can use this equation.

Suppose 10000 bacteria is required to fill the cup and it takes 1 hour (60 min) to form 10000 bacteria.

Answer 2

Dear Student,

Various bacteria reproduce by different rates according to their doubling time.

◆ Answer -

Approximately 8 bacteria are obtained.

● Explanation -

Usuall most of the bacteria doubles themselves in 20 min. T = 20 min.

Given that time taken for culture is t = 60 min.

No of bacteria at the start is N0 = 1

So now, bacteria obtained after 1 hour will be -

N = N0 × 2^(t/T)

N = 1 × 2^(60/20)

N = 2^3

N = 8 bacteria.

Here, after 1 hr approximately 8 bacteria are obtained.

Thanks dear. Hope this helps you...
