The population of bacteria in a petri dish doubles every 40 seconds. The population of the bacteria is initially 400 organisms.

What unit is most appropriate for the time at which the number of bacteria is 300?

 

 

  • hour
  • bacteria per hour
  • second
  • bacteria per second

Since you are looking for a TIME       second or hour    are units of time  the other two are RATES

  SInce this colony multiplies every 40 seconds,   seconds would likely be the BEST answer.

Does adore.nuk mean brain-dead or stu.pid

I think these bacteria infected his brain. There is no cure. Schedule yourself for euthanasia.
