Quizplus · Accepted Answer

A person who lives at sea level has adapted to a lower altitude and thus has adapted to lower altitudes' lower oxygen levels. When this person moves to a higher altitude like the Rocky Mountains, the air pressure decreases, leading to lower oxygen levels. This decrease in oxygen results in an increase in the production of red blood cells to compensate for the lower oxygen supply. Therefore, the person would experience an increase in red blood cell count.
