Answer: look at the explanation below
Explanation:
1- are three major circumstances that stimulate drinking: (1) a deficit of body water (hypohydration), (2) an excess of osmoles (electrolytes) in the cellular and extracellular fluid (ECF) compartments, (hyperosmolality), and (3) consumption of dry food (prandial) (Adolph, 1967).
2- YOU DO NOT DETERMINE PRECISELY WHICH SOURCES DO MEAN:
- If you want nutritional sources: juicey or fluid fruits is rich in water content e.g. orange ...
-But if you want environmental sources to gain water:
three main sources of water: groundwater, surface water and rainwater. In arid regions where seawater is accessible (such as in the Middle East), desalination (the removal of salts from water) is used to generate drinking water.
Hope that will assess you.
