Answer to Question 1

B
Feedback:
Animal proteins, dairy products, legumes are rich natural sources of phosphorus. Soft drinks contain phosphoric acid. Phosphate additiveswhich are often added to commercially prepared foods to extend shelf life, improve taste, improve texture, or retain moisturecan be significant sources of phosphorus.

Answer to Question 2

1
Rationale: Water has many important roles in the human body including transportation of nutrients and other substances; regulation of the core body temperature; removal of waste products; and lubricant for joints, eyes, and mucous membranes. Water is lost during fecal elimination, but does not cause the process. Weight is affected by the amount of water in the body, but is not stabilized by it. Euhydration refers to a state of water balance.
