Question

wednesday 9/10: respiration lab
which of the following activities was suggested in the lab to increase breathing rates?
a) sitting quietly
b) exercising
c) breathing
d) counting

Explanation:

To determine which activity increases breathing rate, we analyze each option:

• Option A: Sitting quietly is a resting activity and typically does not increase breathing rate.
• Option B: Exercising increases the body's demand for oxygen, so the respiratory system responds by increasing breathing rate to supply more oxygen and remove more carbon dioxide.
• Option C: Breathing is the normal process of gas exchange; the act of just breathing (without exertion) doesn't increase the rate beyond normal.
• Option D: Counting is a mental or low - physical - effort activity and does not increase breathing rate.

Answer:

B) Exercising
