What moves the food from your mouth to your stomach when you swallow? undulatory muscle contractions pressure difference between zones peristaltic muscle contractions gravity?

The appropriate answer is the peristaltic muscle muscle contractions.
Peristalsis, involves involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but may take place in other hollow tubes of the body, that occur in progressive wavelike contractions. Peristaltic waves occur in the esophagus, stomach, and intestines.

The correct answer is peristaltic muscle contractions.
  Peristaltic muscle contractions include contraction and relaxation of smooth muscles that produce a peristaltic wave, which propels the bolus (mix of food and saliva which travels down the digestive tract). Muscles contract behind the bolus to prevent it from being squeezed back into the mouth and the rhythmic contractions work to rapidly force it into the stomach.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

starchy vegetablesnon-starchy vegetables

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
