Answer to Question 1

C
Phospholipids are valuable in foods and in the body because they are soluble in water and fat at the same time. This makes them useful emulsifiers and important components of cell membranes. Phospholipids have no particular role in carrying fat-soluble vitamins. They are not used as fat substitutes. They do not function as antioxidants.

Answer to Question 2

A
Feedback:
Calcium is the most plentiful mineral in the body, making up about half of the body's total mineral content. Almost all of the body's calcium is found in the bones and teeth.
