All of the following provide about 5 grams of fat each except: a. 1 1/2 teaspoons of margarine b. 1 tablespoon of heavy cream c. 1 teaspoon of oil d. 1 tablespoon of regular salad dressing e. 1 cup of sour cream

answer: c

explanation:

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
