Answer: C
Muscular system, gastrointestinal system and excretory system are required for the process.
<h3><u>Explanation:</u></h3>
Cheetos is a nutrient rich diet which is actually a snack. Its a hard food, so needs to be chewed which uses the muscular system for chewing. The muscles of jaw like masseter and temporalis are required.
Now as the Cheetos are crunched, they need to be digested into finer particles and finally into the absorbable particles. This uses the gastrointestinal system. The enzymes digest the food and the villi of small intestine helps in the absorption.
The absorbed food are metabolized in liver and some excretory products are produced. They are excreted using the excretory system.

Enzymes are biological catalysts which accelerate chemical reactions (reactions are millions of times faster than without them). Every enzyme has an active site which binds substrates and converts them into products.
It weakens the infection. It also helps him not catch future infections and controls the spread of the infection.
