Answer to Question 1

C
Sphincter muscles control the movement of food in and out of the stomach. They do help prevent reflux, but this is not their name. They are not involved in peristalsis. Segmentation occurs as circular and longitudinal muscles cause food to move backwards and forwards in the gut.

Answer to Question 2

2, Whole grain spaghetti; 3, Oatmeal
Rationale: High glycemic index foods like potatoes are made of higher amounts of simple carbohydrates that cause a more rapid rise in blood glucose. Whole wheat spaghetti is an example of a complex carbohydrate that causes a slower elevation in blood glucose after it is eaten. Oatmeal is an example of a complex carbohydrate that causes a slower elevation in blood glucose after it is eaten. Bagels are a high glycemic index food that is made of higher amounts of simple carbohydrates that cause a more rapid rise in blood glucose. Corn flake cereal is a high glycemic index food that is made of higher amounts of simple carbohydrates that cause a more rapid rise in blood glucose.
