I would say that the way perspiration is related to recovery after exercise is that the body replenishes water and ions during perspiration so the muscles can rest and repair during the cool down period.
Positioning the child on the side (side-lying position) is the priority action after tonsiloectomy. It will permit the flow of secretions (like blood) from the mouth that could block the child's airway (airway patency is the priority). So, the most important thing is to maintain an open airway. Excessive coughing could actually trigger bleeding. The child will be on nothing-by-mouth status during the immediate postoperative period.
When the swimmer is unable to take in enough oxygen for the sprint, the ATP (Adenosine triphosphate) will be compromised. In such conditions, the body will use anaerobic respiration to produce the ATP. Anaerobic respiration takes place in the absence of oxygen. It used the electron acceptors in place of the oxygen in the respiratory cycle. The amount of the ATP produced is, however, less in anaerobic respiration.
Hence, the answer is 'Option C - Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen'.
Light. That's the chemical equation for photosynthesis
