Assume tu inoculated 100 facultative anaerobic cells unto nutrient agar and incubated the plate aerobically. You then inoculated 100 cells of the same species unto nutrient agar and incubated the second plate anaerobically. After incubation for 24 hours, you should theoretically have:
A) More coloneis on the aerobic plate
B) More colories on the anaerobic plate
C) The same number of colonies on both paltes
D) Fewer colonies on the anaerobic plate
E) None of the above
