Question

How does the bar-headed goose accumulate oxygen in extreme environments (high altitude, low oxygen)?

MCQ Options:
a. By holding its breath for extended periods
b. By relying on anaerobic respiration
c. By having a higher red blood cell count
d. By using specialized oxygen-absorbing feathers

Answer 1

Bar-headed geese accumulate oxygen in extreme environments (high altitude, low oxygen) by having a higher red blood cell count, which allows them to transport more oxygen to their tissues and organs.

Step-by-step explanation:

Birds have evolved a respiratory system that enables them to fly and obtain the necessary oxygen for their high-energy activities. In high altitudes with low oxygen levels, birds like the bar-headed goose have adapted by having a higher red blood cell count. This allows them to transport more oxygen to their tissues and organs, enabling them to survive and thrive in extreme environments.
