Explanation:

1. Lipids are largely nonpolar (hydrophobic) due to their hydrocarbon chains, so this statement is true.
2. Triglycerides are synthesized from fatty acids and glycerol (obtained from food or metabolism), so this is true.
3. Lipids have diverse functions (e.g., energy storage, cell membrane structure, hormone signaling), so not all lipids have the same function (false).

Answer:

1. "Lipids are a diverse group of molecules that are mostly nonpolar." - True
2. "Cells use fatty acids and glycerol from foods to build triglyceride molecules." - True
3. "All lipids have the same function in the body." - False
