Answer: C. If we were able to check the person's blood sample before and after breathing into the brown paper bag, we would see a decrease in blood pH and an increase in pCO2.
Explanation:
A hyperventilation is a condition in which the person breathe faster than the normal rate of breathing. In hyperventilation the body tries to expel out the carbon dioxide in the body.
Grabbing a brown paper bag and breathing repeatedly into it is recommended in the hyperventilation condition. The carbon dioxide gas will be accumulated in the bag. This will restore the normal breathing.
C. is not true for this scenario this is because of the fact that after this process the carbon dioxide levels in the blood are likely to decrease in the blood.
