Question

An egg sandwich got contaminated with 10 cells of a staphylococcus. It was exposed to outside for 4 h at 37c. Later, it was found to contain 40960 cells. What is the doubling time of staphylococcus?

Answer 1

Each cell gave rise to 4096 cells after 4hrs.

The no.of cells after n number of divisions is 2^n.

And, 2^12 = 4096

So, after 12 divisions, it formed 4096 cells. That means, for 12 divisions, it took 4hrs.

For 1 division, 4/12= 1/3 hrs or 20 mins.

I have no idea what is the significance of temp 37c,here.

But if the answer is correct, please mark me brainliest, it will bring a smile:))
