Question

at high altitudes, there is less oxygen in the air than at sea level. when a person takes a trip to the mountains, in which ways does their body adjust to maintain homeostasis? the body produces more red blood cells to increase the rate of oxygen delivery to the cells the body produces more red blood cells to decrease the rate of oxygen delivery to the cells breathing rate increases to bring in the amount of oxygen the body needs

Explanation:

Red blood cells carry oxygen. At high - altitudes with less oxygen, the body produces more red blood cells to increase oxygen delivery. Also, increasing the breathing rate helps take in more oxygen to meet the body's needs for maintaining homeostasis.

Answer:

The body produces more red blood cells to increase the rate of oxygen delivery to the cells
Breathing rate increases to bring in the amount of oxygen the body needs
