The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Context**: A man from the sea coast is moving to a high altitude location, specifically Everest peak. This change in altitude is crucial for understanding the physiological responses that will occur. 2. **Recognizing the Effects of Altitude**: At high altitudes, such as Everest peak, the atmospheric pressure is significantly lower than at sea level. This means that the amount of oxygen available in the air is also reduced, which is often referred to as "thin air." 3. **Impact on Breathing**: Due to the lower atmospheric pressure and reduced oxygen availability, the diffusion of respiratory gases (like oxygen) in the lungs becomes more difficult. This means that the body is not able to take in as much oxygen with each breath as it would at sea level. 4. **Body's Compensatory Mechanism**: To compensate for the decreased oxygen availability, the body responds by increasing the rate of breathing (respiratory rate). This is an attempt to take in more oxygen to meet the body's demands. 5. **Heart Rate Response**: Along with the increase in breathing rate, the heart rate also increases. This is because the heart needs to pump more blood to deliver the limited oxygen available in the blood to the tissues and organs. 6. **Conclusion**: Therefore, when a man from the sea coast goes to Everest peak, both his breathing rate and heartbeat will increase to adapt to the high altitude conditions. ### Final Answer: His breathing and heartbeat increase. ---
