here are the answers for Experiment 3.2:

EXPERIMENT 3.2: PULSE RATE EXPERIMENT

AIM
To study how biological actions respond to pulse count.

PROBLEM STATEMENT
Does the pulse count increase when executing heavy tasks?

HYPOTHESIS
The pulse count will increase when executing heavy tasks.

VARIABLES

• Manipulated variable: Type of activity (e.g., at rest, walking, jogging/vigorous activity)
• Responding variable: Pulse count (beats per minute)
• Controlled variable: Individual student, duration of pulse count (1 minute), method of counting pulse

RESULTS

• The table for results requires experimental data, which is not provided.

QUESTIONS

1. The pulse rate increases after vigorous activity.
2. The higher pulse rate allows the blood to transport oxygen and glucose faster to the cells for cellular respiration.
3. Sweat is produced when doing heavy tasks to cool the body down as increased metabolic activity generates heat.

CONCLUSIONS

1. From the results, the hypothesis is accepted (or supported).
2. Pulse rate increases after vigorous activity.
