The percentage of blood (by volume) occupied by corpuscles in two animals (1 and 2) which can survive at low as well as high altitudes is shown in the table:
Mark the correct interpretation:
1. Animal 1 is poorly adapted at high altitude as compared to animal 2
2. Animal 2 is poorly adapted at high altitude as compared to animal 1
3. Affinity of Hb for oxygen in animal 1 is higher at lower altitude
4. Hb of animal 2 shows higher affinity for oxygen as compared to animal 1
| Animal | Altitude | Corpuscles (%) |
| Animal 1 | Sea level | 34 |
| Animal 2 | Sea level | 33 |
| Animal 1 | 4700 m | 50 |
| Animal 2 | 4700 m | 34 |
Mark the correct interpretation:
