Question

At higher altitudes, the air becomes rarer and amount of oxygen per liter of air decreases.
Increase in all of the following would compensate this decrease for performing normal biological functions of our body, except

• A. The concentration of haemoglobin
• B. The number of red blood cells
• C. The temperature of the body
• D. The rate of breathing

Answer 1

Answer: (C)

The temperature of the body

Higher altitudes have less pressure than planes and the air is thin that means the number of oxygen molecule present in air is less than the air of planes normally known as altitude sickness.

To compensate these decrease body adapted various methods. These are:-

1. The concentration of RBC increase which ultimately increases the haemoglobin concentration as it helps in carrying more oxygen.
2. The rate of breathing increase to get more oxygen.

So the correct option is 'The temperature of the body'
