How do oxygen and carbon dioxide levels in the blood affect respiration?
Effect of oxygen and carbon dioxide levels in the blood, on respiration:
How plants do photosynthesis and respiration at the same time in the day as in respiration,oxygen is inhaled and carbon dioxide is exhaled and in photosynthesis,carbon dioxide is inhaled and oxygen is exhaled.So they are opposite.So how do they carry out both the processess at the same time?
1)how do the number of alveoli increase affect the exchange of oxygen and carbon dioxide?
