Quizplus · Accepted Answer

At high altitude, the atmospheric pressure is reduced, resulting in a decrease in the availability of oxygen. This leads to a reduction in oxygen that is bound to hemoglobin (option A). To compensate for the reduced oxygen availability, the heart rate response to a fixed level of exercise increases to enhance oxygen delivery to the working muscles (option C). Therefore, both option A and option C are correct. Option B is incorrect as exercise at high altitude would lead to an increase in resting heart rate due to the reduced oxygen availability.
