Answer:

1 cell divides after every 20 minutes , so the process will be as follows...

1 → 2 → 4 → 8 → 16 → 32

Answer 2

Answer:

100 minutes or 1 hour 40 minutes

Explanation:

if it divides in every 20 minutes

then,

1 cell require 20 min to form 2 cells

2 cells will require 20 min to form 4 cells

4 cells will require 20 min to form 8 cells

8 cells will require 20 min to form 16 cells

hence, 16 cells will require 20 min to form 32 cells

therefore,

1 cell will require 20+20+20+20+20 = 100 minutes= 1 hour 40 minutes
