A cells relatively constant internal physical and chemical conditions are called Homeostasis.
Answer:
Increase
Explanation:
As CO2 enters the blood, most of it is converted to the carbonic acid in a reaction catalyzed by carbonic anhydrase. The carbonic acid dissociates into hydrogen ions and bicarbonate ions. As the H+ concentration increases, the blood pH decreases. Thus, the increased partial pressure of CO2 produces a more acidic environment. Increasing the volume of air that reaches the alveoli and takes part in gaseous exchange will increase the rate of removal of CO2 from the blood. The reduced CO2 levels in the blood would increase the blood pH.
False, Animal cells do “not” have cell walls.
Your "Digestive System" breaks down food into molecules that are then absorbed into your body.
