Organisms can show morphological , physiological and behavioural adaptations. By which of these adaptation altitude sickness is overcome ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Altitude Sickness**: Altitude sickness occurs when an individual ascends to high altitudes too quickly, leading to low oxygen levels in the blood, a condition known as hypoxia. Symptoms include dizziness, fatigue, and in severe cases, loss of consciousness.
