Temperatures between 40 and 140 degrees f. are considered to be in the "danger zone" if it has not consistently been held at or below 40 degrees f. do not eat it.
What variables must be kept constant
Yogurt is kept in a fridge because it needs to to stay cool & fresh for when you eat it. You can put it in a freezer as well if you have yogurt tubes and you want to make it into an ice lollypop1
In an experiment, variables that must be kept constant are called control variables. Two common examples include temperature and pH levels. These variables should be kept constant to ensure that any changes observed in the dependent variable are a result of the independent variable being tested.
Milk has a yogurt culture added to it, and is kept at the correct temperature for the bacteria of the culture to grow. The milk is converted to yogurt. You can then add any flavorings or additions you like.
