If you are referring to pathogenic bacteria, then you are looking for the upper and lower limits of the Temperature Danger Zone. Under the recent version of the FDA Model Food Code, those would be 135 degrees Fahrenheit (57.2 degrees C) and 41 degrees Fahrenheit (5 degrees C).
Those limits may vary depending upon the course you are taking or the legal authority under whose jurisdiction your business is in. Use their stated limits, unless the FDA Model Food Code's limits are the same.

What type of condition will support the rapid multiplication of bacteria?
A condition that provides an ideal environment for bacterial growth, such as warm temperatures, high humidity, and a plentiful nutrient supply, can support the rapid multiplication of bacteria. Additionally, conditions that inhibit or prevent the action of certain bacteria-killing agents, such as antibiotics or disinfectants, can also contribute to their rapid multiplication.
Can there more less or the same amount of growth on the expose plates when incubated at two different temperatures?
It is possible but not likely. The warmer temperature normally favors more rapid growth. Some bacteria or molds prefer cooler temperatures.
What type of food properties do not allow harmful bacteria to multiply rapidly?
Foods with low water activity, high acidity, or high salt/sugar concentrations tend to inhibit the growth of harmful bacteria by creating an unfavorable environment for their proliferation. Additionally, processed or cooked foods that are stored properly can prevent rapid bacterial growth due to removal of nutrients and control of temperature.
What are the three different growth patterns of bacteria?
The three different growth patterns of bacteria are exponential growth, lag phase, and stationary phase. Exponential growth is the rapid phase of growth where bacteria multiply quickly. Lag phase is a period of adaptation where bacteria prepare to divide. Stationary phase is when growth slows down due to limited resources or build-up of waste products.
What are the conditions in which binary fision takes place?
Binary fission typically occurs in prokaryotic cells, such as bacteria, under favorable conditions with abundant nutrients and optimal temperatures. The cell replicates its DNA and elongates before dividing into two genetically identical daughter cells. This process allows for rapid reproduction and population growth in favorable environments.
