question 3 (1 point)
all of the following are food groups from the myplate system except ____.
a fruits

d protein foods

Explanation:

Question 1

To determine the nutrient for building and maintaining cells/tissues, recall: Carbohydrates (a) provide energy. Fats (b) store energy/insulate. Protein (c) is made of amino acids, essential for cell/tissue structure/repair. Vitamins (d) regulate processes. So protein is correct.

Analyze vitamin types: Major (a) is not a vitamin classification. Fat - soluble (b) vitamins (A, D, E, K) dissolve in fat, are stored. Trace (c) refers to minerals. Water - soluble (d) vitamins (B, C) dissolve in water, not stored long. So fat - soluble matches.

MyPlate food groups: fruits (a), grains (b), protein foods (d), vegetables, and dairy. Oils (c) are not a MyPlate food group (they are a fat source, not a main food group).

Answer:

c. Protein
