Gluten is naturally found in which of the following grains?

Rye Barley Wheat

The liver, gallbladder, and pancreas are part of the digestive system but are considered to be _____ structures.

accessory

The _____ in gastric juice destroys the biological activity of proteins, converts inactive digestive enzymes to their active form, partially digests food protein, and makes dietary minerals soluble so that they can be absorbed.

acid

The acidic environment of the stomach is beneficial in
