2. Have test subject do either sit ups, push ups, or sprint for one minute.
3. Take test subject's blood pressure.

Tom and Jesse run the same tests on John every day for one week. Running the same test, for one week, is an example of

Answer 1

Tom and Jesse's test on John's blood pressure after exercising is an example of a controlled experiment where they measure the effects of exercise on blood pressure.

Step-by-step explanation:

Tom and Jesse's procedure to test the effect of exercise on blood pressure is an example of a controlled experiment. In their experiment, they are manipulating the independent variable, which is the exercise, to observe the effect on the dependent variable, John's blood pressure. By testing the same subject, John, under controlled conditions and measuring the changes in blood pressure after exercising, they can determine the effects of the specific exercise on blood pressure. These results can then be compared to the initial resting blood pressure to assess any differences due to the exercise regimen.
