Which of the following is correct regarding acclimatization? A. Decreases in arterial POâ cause the peripheral chemoreceptors to become less responsive to increases in PCOâB. At high altitudes, hemoglobin's affinity for Oâ is increased because BPG concentrations increase. C. When blood Oâ levels decline, the kidneys produce more erythropoietin, which stimulates breakdown of red blood cells in the spleen D. High-altitude conditions always result in lower-than-normal hemoglobin saturation levels because less Oâ is available to be loaded

D. High-altitude conditions always result in lower-than-normal hemoglobin saturation levels because less Oâ is available to be loaded

Explanation:

Acclimatization is a process in which body of organisms adjust itself according to the conditions of the environment. This process occurs for a short period of time. At normal altitude, hemoglobin saturation levels becomes high. When a person goes to a high altitude, the hemoglobin saturation levels decreases because oxygen is a heavier gas and we go higher its concentration reduces in the atmosphere.
