Question

with low oxygen levels, your breathing rate will increase. when your oxygen levels rise, what is the appropriate response? keep breathing rate high return breathing rate to baseline increase heart rate stop breathing

Explanation:

The body's respiratory system maintains homeostasis. When oxygen levels are low, breathing rate increases to get more oxygen. When oxygen levels return to normal (rise), the breathing rate should return to its baseline (normal) rate. "Keep breathing rate high" is unnecessary once oxygen is sufficient. "Increase heart rate" is not directly related to correcting breathing rate after oxygen rise. "Stop breathing" is dangerous and incorrect. So the appropriate response is to return breathing rate to baseline.

Answer:

B. return breathing rate to baseline (assuming the options are labeled A: keep breathing rate high, B: return breathing rate to baseline, C: increase heart rate, D: stop breathing)
