Question

A bacterial cell can double in number every 20 minutes. If one bacterial cell was present at the start of an experiment. How many cells would be present after 4 hours

Answer 1

60 minuets are in 1 hour, and it will split up times in an hour, that means that there will be cells present.

20 minutes = 2 cells

40 minutes = 4 cells

1 hour = 8 cells

1 hour 20 minutes = 16 cells

1 hour 40 minutes = 32 cells

2 hours = 64 cells

2 hours 20 minutes = 128 cells

2 hours 40 minutes = 256 cells

3 hours = 512 cells

Answer 2

There would be 4096 bacteria cells present.

2^12 = 4096
