Answer is B in my opinion
Answer:
Mechanical digestion:Begins with chewing Involves the teeth and tongue
Chemical digestion: Breaks down starch, protein carbohydrates, fats, and nucleic acids. Salivary glands produce an important substance for this type
Requires pancreatic juices and enzymes produced by the wall of the small intestine
Explanation:
Mechanical digestion starts in the mouth, it involves the breaking down of food into smaller particles.
Chemical digestion involves the breaking down of food into nutrients component that can be absorbable and used by the body cells.
