You perform a serial dilution and determine that the original number of cells in your sample was 12, 000. How many bacteria will be present in 12 hours if the generation time is 15 minutes (assume unlimited food and clean environment)?

3.4ˣ bacterial cell.

Explanation:

Generation times is 15 minutes then 4 generation we can get in 1 hour.

so, in 12 hours we can get 12ˣ4= 48 generation.

original number of cell sample was 12000

then bacteria present in 12 hours  12000ˣ= 3.4ˣ.

the correct answer is - ability to find a mate
