Explanation / Answer

1) The correct option is d. the relations between food and health.
Nutrition is the process, which provides and obtains the food that are necessary for health, growth and development.
2) The correct option is a. Lipid.
Carbohydrates, lipids, and proteins are energy yielding nutrients, which are required in the diet called as macronutrients.
3) The correct option is d. 135.
fat provides 9 calories per gram, then the 15 grams of fats = 9 x 15 = 135 calories.
4)The correct option is d. 888.
Protein and carbohydrates both contain 4 calories per grams and fat provides 9 calories per gram.
Then, 62x4+70x4+40x9 = 888 calories.
