Which one of these is correct and why are the rest incorrect
Transcribed Image Text:### Understanding Physiological Responses to Environmental Changes
**b. Increased Breathing Rate with Altitude:**
As a person gradually ascends in altitude, the reduction in oxygen levels causes the breathing rate and depth to become progressively greater. The increased ventilation keeps oxygen levels from declining as much as it would with a slower breathing rate.
**c. Muscle Growth from Weightlifting:**
When a person regularly lifts heavyweights, muscles gradually become larger and stronger.
**d. Comprehensive Adaptations:**
All of the above.

In summary, our bodies exhibit fascinating adaptations to both environmental changes, such as altitude, and physical activities like weightlifting. These physiological responses are crucial for maintaining functionality and improving strength.
