What is the formula for doubling the bacteria growth rate every 2 minutes in 1 hours?

I think the question means to say that the growth rate is (double every 2 minutes).
doubling interval = 2 minutes
1 hour = 60 minutes = (60 / 2) = 30 doubling intervals
Starting with 1 bacterium and reproducing asexually (do bacteria do this ? What do I know. I'm only an EE.) . . . . .
If all survive, then the population after doubling 30 times = 230 = 1,073,741,824 bugs.

An exponential growth function represents a quantity that has a constant doubling time?
True
What is the explicit formula for the number of bacteria in generation n?
The answer will depend on the initial population and the growth rate. Since these will vary from one situation to another, it is not possible to give a specific answer.The general answer isP(n) = P(0)*xn where P(t) is the population in generation n, and x is the multiplier for the growth.
Is it true that if you start with one penny and doubled it every day for thirty days you would have 5368709.12?
Yes, if you count day 1 as the day you have one cent, then on day 30 you have 229 cents ($5,368, 709.12).If the first of the 30 days is the first day that you double it, then on Day 30 you will have 230 cents ($10,737,418.24).You use the formula: C=.01*(2)x where the value x is either 29 or 30Where C=the total cash for the given day (which you have in the formula as 30), the (2) is the growth formula (doubling every day), and 1 cent (.01) as your starting amount.This demonstrates the concept of exponential growth.
What is the exponential formula for population growth?
exponential decay formula is y=A x Bx
Population growth rate definition?
Population growth rate is the rate at which populations change in size over time as a fraction of the initial population. The formula used to measure growth rate is (birth rate + immigration) - (death rate + emigration).
What conditions will cause a population to have exponential growth?
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.
A popalation of bacteria that doubles its size every 20 minutes exhibits growth?
Yes it exhibits growth
What is specific growth rate constant?
it is used as a way of measuring how fast cells are dividing, defined as the doubling rate, and it is worked out with the following formula: k=(Log Nt - Log No)/ t x Log 2 this goes to the slightly easier form of; k= 3.32 x (Log Nt - Log No)/ t where k= growth rate constant Nt = number of bacteria at second time No = number bacteria at start t = time gone. (obvioulsy you take the logs of Nt and No in the formula)
What population of bacteria that doubles its size every 20 minutes exhibits growth?
um if you use the simple doubling time formula, you'd do it like this: (final pop. #) = (original pop. #) x 2^(time it takes for it to double/ how many times it doubles) so you're missing some info. find out either the initial pop or the final pop. your probably referring to one bacterium, but yeah, double check (haha, get it? double?haha)
What is the doubling time for ecoli?
Under optimal growth conditions the doubling time for E. coli is 20 minutes. This is however, a textbook figure and in practice the doubling time is slightly longer. Under standard, non-bioreactor type laboratory conditions, aerated (shaking) E coli cultures grown in LB or similar media will have a doubling time of around 30 minutes. Note that growth rates differ between strains, B strain derivatives (often used for protein expression) grow faster than K strain derivatives (generally used for cloning). Also, strains harboring plasmids and strains grown under selective pressure will often have longer doubling times.
a bacteria population is growing exponentially with a growth factor of 1/10 each hour by what growth factor does the population change every 15 minutes?
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.
What are the three ways that a growth rate may be started or expressed?
It may be stated as a doubling time, a birthrate per female, or a percentage of growth per year.
An exponential growth function represents a quantity that has a constant doubling time?
True
What are two responsibilities that governments have with respect to population growth?
consider doubling time
Does an exponential growth function represents a quantity that has a constant doubling time?
False
What factors make doubling time decrease?
The rate of growth and, unless the relationship is exponential, the frequency of each growth cycle.
What effect does Mercurochrome have on bacteria?
It will affect the growth of the bacteria.
