Freezing bacterial cultures slows the Death Rate of the bacteria. When bacteria is frozen it goes into a sleep state and does not grow or multiply.

12 A given species of bacteria is known to require 100 different nutrients 99 of these are in optimum quantities but one is limited You would expect that population growth would be?
limited by the quantity of that nutrient - its the limiting stepthe actually rate of growth depends on the relationship between tha nutrient and the growth rate if its a linear relationship then growth rate = k[Nutrient]
What is a rapid growth rate?
Well... A Growth rate is the how fast sometning grows, and rapid means speedy. Therfore, something which has a rapid growth rate is something which grows quickly.
What causes expotential growth?
Exponential growth is when the growth rate is a function of the amount. Another way of saying it is, the more there is, the higher the growth rate. This occurs in just about all populations including humans. This growth will continue at an exponential rate until some other limiting factor reduces the growth rate such as famine or disease. For more information look up the "Law of natural growth and decay."
What happens to the rapidly dividing cells when the healing process nearest completion?
The rate of cell division slows down, controls on growth are restored, and everything returns to normal.
What is the multiplication rate of salmonella bacteria?
potato
What is Exponential growth phase of microbial growth?
When the bacteria double at a constant rate
How does the term exponential growth apply to bacteria?
bacteria cells grow at a high speed rate.
What happens when the birth rate is more than the death rate?
Population growth its that simple
When large areas of continents are covered by ice what happens to the rate of chemical weathering?
they freeze to death
What happens to the speed of particles when freezing occurs?
When molecules freeze the rate of speed they go at tends to slow down

How does the population growth curve of humans compare with that of bacteria on a petri dish?
The current population of humans is growing at a rapid rate and not indicating it is slowing down to a carrying capacity. Bacteria exhibit this type of growth when growing in a petri dish in a lab.
What happens to a population's growth rate with unlimited resources and no deaths?
Major rise in population...obviously.
Can bacteria grow equally on different types of medium?
Possibly. depending on the nutritional requirements of the bacteria and what the medium provides will determine the growth rate (as well as temp, pH etc)
When food is put in the refrigerator all bacteria?
The growth of bacteria slows but does not stop. The food will still spoil but at a much slower rate.
How does dehydration affect bacteria?
dehydration affects bacetria by slowing down the rate of growth since there is need for some amount of moisture
How many hours from 1 to 500 bacteria?
It depends on their rate of growth which will depend on the matrix and temperature as well as the species - none of which are specified.
