In this case, the statement that people who exercise for an hoour may have lower cholesterol level is HYPOTHESIS. The cholesterol level would be the DEPENDENT VARIABLE.
An hypothesis refer to a proposed statement based on prior knowledge, which is used as a starting point in scientific experimentation.
In scientific experiments, there are always two variables, independent and the dependent variable. The independent variable is the variable that is changed or controlled in a scientific experiment in order to determine its effects on the dependent variable.

Cholesterol is a waxy and fatty molecule, which can have good and adverse effects on health. The amount of cholesterol in the body is variable and is different in each body type.

In the experiment, the hypothesis states that the people who exercised daily have lower amounts of cholesterol.

The scientist performed the experiment on the two sets of population, one in which they performed exercise and the other one not working out at all.

In this experiment, the independent variable is the set in which change in an experiment is to determined concerning the dependent variable.

The result of the test has shown that the population exercising daily has lower amounts of cholesterol compared to the set of people not working out as well.

Therefore, in a scientific experiment, results are carried out based on dependent and independent variables.

Answer from: Quest

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
