B)80%.
C)90%.
D)100%.

Question

Quizplus · Accepted Answer

The bar-headed goose is known for its ability to fly over the Himalayan mountains, including Mount Everest, which has an altitude of 29,029 feet (8,848 meters). At this altitude, the atmospheric pressure and hence the oxygen concentration is only around 33% of that at sea level. However, studies have shown that the bar-headed goose is able to maintain near-normal levels of hemoglobin oxygen saturation (around 90%) even at this high altitude, thanks to adaptations in their respiratory and cardiovascular systems. Therefore, the best choice is (C) 90%.
