Peristalsis is the involuntary movement of the muscles that move food through the digestive system.

- Peristalsis occurs in all parts of the gastrointestinal tract from esophagus to the rectum.

Answer;
A. During active transport, a material may be moved from an area of low concentration to an area of high concentration.
Explanation;
-Active transport involves movement of molecules or particles against a concentration gradient (from a region of low concentration to a region of high concentration). This movement of particles against the concentration gradient requires an input of energy from the cell in the form of ATP.
- Passive transport on the other hand involves movement of materials from a region of high concentration to a region of low concentration and does not utilize energy. Passive process are processes such as osmosis and diffusion.
