Question

select the true statements.
fats are less energy - dense than carbohydrates.
fats provide energy for the body during rest.
one gram of carbohydrate provides less than half the amount of energy in one gram of fat.
fat - soluble vitamins are dissolved by triglycerides.

Explanation:

• Fats are more energy - dense than carbohydrates. One gram of fat provides 9 kcal, while one gram of carbohydrate provides 4 kcal. So the statement "Fats are less energy - dense than carbohydrates" is false.
• During rest, the body can use fats as a source of energy. So the statement "Fats provide energy for the body during rest" is true.
• Since 4 kcal (energy from 1g carbohydrate) is less than half of 9 kcal (energy from 1g fat, \(4<\frac{9}{2} = 4.5\)), the statement "One gram of carbohydrate provides less than half the amount of energy in one gram of fat" is true.
• Fat - soluble vitamins (A, D, E, K) are dissolved by triglycerides (a type of fat). So the statement "Fat - soluble vitamins are dissolved by triglycerides" is true.

Answer:

• Fats provide energy for the body during rest.
• One gram of carbohydrate provides less than half the amount of energy in one gram of fat.
• Fat - soluble vitamins are dissolved by triglycerides.
