Question

If an E.coli cell divides every 20 minutes, what will be the number of cells in the test tube after 6 hours
(a) 128
(b) 256
(c) 512
(d) 1024​

Answer 1

Explanation:

According to the question, in a 20 minutes cycle, cells double. In 2 hours i.e 120 minutes there will be 6 cycles of 20 min each. If we start from 10 bacteria, then after 6 cycles of 20 minutes each (2 hours in total), we will have 10x 2^6 cells after 2 hours.

So, the correct answer is '2^6 x 10'.
