This is a bonus question. If you start with eight cells of a bacterium that has a generation time of 30 minutes and you let it grow for 3 hours, how many bacteria will you end with? (Hint: Use Nt = N0 × 2n.)

Organisms that grow better when there is oxygen available but can live without it are referred to as
