Question

The high-altitude adaptation seen in Tibetans involving increased hemoglobin is classified as:
Options
A Structural — shorter limbs
B Behavioral — cultural farming techniques
C Physiological — increased hemoglobin levels
Correct Answer
D Behavioral — migration to lower altitudes
Correct Answer

Option C is the correct answer.

Detailed Explanation

Increased hemoglobin concentration in Tibetans is a physiological adaptation to high-altitude hypoxia (low oxygen). Higher hemoglobin levels enhance oxygen-carrying capacity of the blood, improving oxygen delivery to tissues in low-oxygen environments.

Hint

This blood-based adaptation enhances oxygen transport in thin air.
