Explanation:

For the statement "A gram of protein supplies more energy than a gram of fat":

• Explanation: Fats (lipids) provide more energy per gram (about 9 kcal/g) than proteins (about 4 kcal/g). So this statement is false.

For the statement "Lipids are mostly hydrophobic":

• Explanation: Lipids are non - polar or have a large non - polar region, which makes them mostly insoluble in water (hydrophobic). So this statement is true.

For the statement "The structure of a lipid impacts its properties":

• Explanation: The structure - function relationship is a key concept in biology. Different lipid structures (like triglycerides vs phospholipids) lead to different properties (e.g., energy storage vs cell membrane structure). So this statement is true.

Answer:

s:

• "A gram of protein supplies more energy than a gram of fat": False
• "Lipids are mostly hydrophobic": True
• "The structure of a lipid impacts its properties": True
