A bacteria splits in half after 20 minutes, so that after 20 minutes there are 2 bacteria, and after 40 minutes there are 4 bacteria. How many bacteria will there be after 2 hours?
45 minutes
20 minutes = 1/3rd of an hour8 hours = (8 x 3) = 24 thirds of an hour = 24 divisions.If all survive and reproduce, the population after 24 divisions = 224 = 16,777,216 bugs.
64x10^18 power or 64,000,000,000,000,000,000. 64 exa bacterium)
Actually, there will be 40960 bacteria after 4 hours.if i did my math right it should be 480 bacteria there will be 480 not that number im a trained math teacher .du.i think 40960 is wrong because don't forget that bacteria only live for minutes

Bacteria grows in less than 1 second except in water .Water washes away the bacteria over and over so first it has to have a good grip on the item .

Yes it exhibits growth

2.5 hours is 150 minutes. So it will have doubled 15 times. 2^15 = 32768 bacteria after 2.5 hours.
The bacteria population has an exponential growth with a factor of 16 per hour. The growth factor has to be determined for the population change each half hour.
If B(t) represents the number of bacteria after t minutes, then B(t) = 200*2^(t/20).
Exponential growth takes place in Bacteria under ideal conditions. It means a rapid increase in population but actually it is doubling of population in a short time.Under ideal condition generation time of bacteria is just 20 minutes i.e. just after 20 minutes no. of Bacteria is doubled. Initially term used for rapid bacterial growth was logarithmic growthbut that proved to be wrong. Term Exponential growth may also be used for population of higher animals but doubling time is much larger as compared to bacteria.
after boiling milk at 75 c for 15 minutes the bacteria or micro bacteria in are dead
45 minutes
