Which of the following are stages in the control of breathing during exercise? Select all that apply.       --During exercise, aerobic respiration causes a rise in CO2  concentration as well as acidity in the blood and cerebrospinal fluid.     --Deeper and more frequent breaths expel more CO2 and this reduces CO2  concentration and acidity in the blood.     --The stimulated brain alters the breathing pattern of the diaphragm and intercostal muscles.     --Increased blood CO2 excites chemoreceptors in the arteries and the brain.
