Multiple Choice
Water assists the body with which of the following functions?
A
Generating nerve impulses
B
Synthesizing DNA directly
C

Verified step by step guidance1
Step 1: Begin by understanding the role of water in biological systems. Water is a universal solvent, meaning it can dissolve a wide variety of substances, which is essential for transporting nutrients and waste products in the body.
Step 2: Recall that water is a major component of blood plasma. Blood plasma is responsible for carrying nutrients, hormones, and waste products to and from cells throughout the body.
Step 3: Consider the process of nutrient absorption. Water helps dissolve nutrients in the digestive system, allowing them to be absorbed into the bloodstream and transported to cells.
Step 4: Examine the removal of waste products. Water facilitates the excretion of waste products like urea and carbon dioxide through processes such as urination and sweating.
Step 5: Eliminate the incorrect options by analyzing their relationship with water. Generating nerve impulses, synthesizing DNA directly, and producing red blood cells are not directly dependent on water in the same way as nutrient and waste transport.
