Question

2 the stomach in the human body contains acid that breaks down food into usable particles. which of the following best describes the process of digestion in the body? a an example of a physical change b an example of a chemical property c an example of a physical property d an example of a chemical change

Explanation:

Digestion involves chemical reactions where food is broken down into new substances (e.g., proteins into amino acids). Physical change (A) would be like changing state (solid to liquid) without new substances. Physical property (C) is a characteristic (like color, density). Chemical property (B) is a substance's ability to react (e.g., flammability), not the reaction itself. Chemical change (D) is a reaction forming new substances, which matches digestion.

Answer:

D. An example of a chemical change
