D) leukocytosis

Question

Quizplus · Accepted Answer

The adaptive response to low oxygen levels at high altitudes is polycythemia, which is an increase in the number of red blood cells in the body. This allows for more efficient oxygen transport to the body's tissues. Megacythemia is not a recognized medical term. Anemia, on the other hand, is a decrease in the number of red blood cells and would be counterproductive in a low oxygen environment, while leukocytosis is an increase in the number of white blood cells and is not directly involved in oxygen transport.
