False Chemical cold packs should be stored in a refrigerator.
A chemical cold pack consists of a bag within a bag. The inner bag contains water. The outer bag typically contains urea or ammonium nitrate. When the inner bag is broken, the water mixes with the chemical in the outer bag, dissolving it. As the chemical dissolves, this is an endothermic reaction. As the reaction absorbs energy, the device cools down.
This cooling will occur independent of whether the cold pack is stored in the refrigerator or not.

The dependent variable - the cholesterol level
Independent variables are the exercise and the drug.
Explanation:
A variable is a factor that can be modified or change. It is the factor that can be measured, altered, controlled in research or the experiment. It can be dependent or independent of their effect.
The independent variable is the factor of the experiment that controlled or manipulated by the researcher and it is considered to have a direct effect on the dependent variable whereas the dependent variable is being checked or tested.
So, in this experiment, the variable that is being tested is the cholesterol level that means it is a dependent variable. The independent variable here is exercise and drug as they manipulate and have an effect on the direct variable.
Thus, the correct answer is -
The dependent variable -the cholesterol level and
independent variables - exercise and the drug.
