Answer:
1. kidneys 2. Lungs 5. Pancreas
Explanation:
The body's balance between acidity and alkalinity in the human body is regarded as the acid-base balance which is measured on the basis of the pH and the concentration of carbon dioxide and bicarbonate in the blood. The organs that controls acid-base balance are lungs, kidneys and pancreas. Theses organs control blood pH by releasing carbon dioxide from the lungs because it is a waste product slightly acidic in nature and excreting excess of acids and bases from the body.
Calcium is one of the most important minerals for the human body. It helps form and maintain healthy teeth and bones.

I believe the answer is the location of energy sources
A facultative anaerobe.
Explanation:
Anaerobes are organisms which can produce energy via the process of fermentation in the absence of oxygen. The anaerobes can be classified as facultative anaerobes and obligate anaerobes.
Facultative anaerobes are those which can carry out respiration in presence of oxygen but can choose to follow the fermentation pathway if oxygen is absent. Fermentation also uses glucose.
Aerobic respiration produces 32 molecules of ATP from one molecules of glucose while fermentation produces only 2 molecules of ATP . Thus when the organism switches to fermentation pathway it utilizes more and more glucose to reach its energy demands.
Considering all the above points we can conclude that observations indicate that the organism is a facultative anaerobe.
