bacteria in the fridge, freezer and danger zone
Bacteria in the fridge slow down, caused by the cooler temperature, they don't work at there optimum rate. In the freezer they are dormant and in the danger zone the thrive.

High risk foods.
Foods that are ready to eat, foods that don't need any further cooking, and foods that provide a place for bacteria to live, grow and thrive are described as high-risk foods.
29 of 40
low risk foods
That are less-likely to cause food poisoning because they have (1) high acid content (pH 4.5 or lower), or (2) low water content. Low risk foods spoil due to their chemical composition (not microbiological activity) and usually have a 'best before' d

function of yeast in bread
Yeast cells thrive on simple sugars. As the sugars are metabolized, carbon dioxide and alcohol are released into the bread dough, making it rise.

conduction
