A student states that exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time. An
experiment is carried out to test this hypothesis. One group of ten students sits quietly before squeezing a clothespin as many times as possible during a one-minute interval. A second group of ten students does 25 jumping jacks before squeezing a clothespin as many times as possible during a one-minute interval. What is the independent variable?
In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.
In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).
The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.
The amine group in the amino acids that constitute the excess protein are removed and converted into urea or uric acid in a process known as deamination.
The remaining portion of the amino acids which is essentially carbon and hydrogen is converted into carbohydrate or fat and later oxidized to generate energy for the body.
