An investigation is carried out to determine the effect of exercise on the rate at which a person can squeeze a clothespin.

Muscle fatigue occurs during this activity when

• carbon dioxide is used up in the muscle cells

• simple sugar is converted to starch in the muscle cells

• proteins accumulate in mitochondria in the muscle cells

• certain waste products collect in the muscle cells

An investigation is carried out to determine the effect of exercise on the rate at which a person can squeeze a clothespin.

The dependent variable for this experiment is the

• time the student was squeezing the clothespin

• number of times the student was able to squeeze the clothespin

• strength of the student

• length of the clothespin

Students were asked to design a lab that investigated the relationship between exercise and heart rate. Heart rate was determined by recording the pulse rate in beats per minute. The students hypothesized that increased exercise results in an increased heart rate. The class results for the experiment are shown in the graph.

Which statement is best supported by the graph?

• Before exercising, the average pulse rate was 65; four minutes after exercising, the average pulse rate was 65.

• After four minutes of exercising, the average pulse rate was 120; two minutes after exercising, the average pulse rate was 120.

• While exercising, the highest average pulse rate was 150; before exercising, the average pulse rate was 65.

• Two minutes before exercising, the average pulse rate was 80; after two minutes of exercise, the average pulse rate was 140
