What type of food properties allow harmful bacteria to multiply rapidly?
There are various food properties that allow harmful bacteria to multiply rapidly; one being the food is low in acid. Two more are moisture and that the food is high in protein.
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.
Does heating yogurt kill the good bacteria?
It can--if you heat it enough. But for yogurt, it really depends on the type of yogurt - mesophiic or thermophiic. With thermophlic bacteria, the dairy liquid is heated to as high as 125 degrees F to allow the bacteria to multiply. Mesophilic bacteria multiply well at room temperature - around 72 degrees F, so the higher thermophilic temperatures would tend to kill them off. Most of the commercially available yogurts found in the USA are thermophilic where mesphilic yogurts are available overseas. Examples of mesohhilic yogurts - Villi, Piima, and Matsoi.
What is the purpose of spores that live within some bacteria?
Spores are a form of reproductive structure that bacteria can produce to survive harsh environmental conditions. They can protect the bacteria from desiccation, heat, radiation, and chemical damage. Spores allow bacteria to remain dormant until conditions improve, at which point they can germinate and resume growth.
Why is it so important not to thaw food at room temperature?
Thawing food at room temperature can allow harmful bacteria to grow rapidly in the outer layers of the food, leading to foodborne illnesses. It is safer to thaw food in the refrigerator, under cold running water, or in the microwave to prevent bacteria from multiplying to dangerous levels.
What type of food properties do not allow harmful bacteria to multiply?
Foods that are high in acid do not allow harmful bacteria to multiply rapidly.

Why are shallow containers best for refrigerating food?
Food that needs refrigeration should be cooled as rapidly as possible and held at that temperature. Shallow containers allow food to cool quickly, lowering the chances for bacteria to grow.
Will your cut get infected if you put hair spray in it?
Probably not. The chemicals in spray cans are typically pretty sterile and relatively pure. It is not likely that they will carry bacteria. However, if the cut has not been cleaned and you spray it, you may be sealing the bacteria in an area that will allow it to multiply and infect the cut.
Why does your belly flap stink?
I assume you are referring to a panniculus, the flap of tissue that someone has after losing weight. Such a flap can develop an odor because the folds allow moisture and bacteria to become trapped under there. Without good hygiene, the bacteria can multiply and give off odor.

What is it about today's society that helps bacteria move quickly around the world?
Have you not heard about the conditions in Libya, Africa, and Syria including other third world countries? People these days don't care much about hygiene so they allow a perfect environment for the bacteria to live in and duplicate rapidly overtaking the molecular world.

What are the main uses of chitosan?
Chitosan is a substance that is widely used in the medical profession, due to it's special properties that allow it to rapidly clot blood. It is a polysaccharide, and research says another use of chitosan could be as a soluable dietary fiber.
What do bacteria possess to allow them to adhere to intestinal lining?
Both bacteria and the lining cells of the intestinal tract have to have mutual attractive proteins. These will allow the bacteria affect the other cells. Many do not and they have no bad effect. We do have billions of bacteria that are beneficial and not harmful. The digestive tract is their normal habitat.
