_____ is an essential nutrient and helps transport other nutrients to cells, carries wastes, and aids digestion.

• A. Carbohydrate
• B. Fat
• C. Protein
• D. Water

Answer: (D)

Water is an essential nutrient because it serves as the medium in which most bodily processes occur. Its ability to dissolve and transport substances lets nutrients move to cells via the bloodstream and lymph. It also carries wastes to the kidneys for elimination and participates in digestion by forming and diluting digestive fluids, aiding digestion and absorption. While carbohydrates, fats, and proteins provide energy and building blocks, they don’t perform these transport and waste-removal roles as water does. This makes water the best fit for the described functions.
