Which best describes the digestive system of arthropods? a incomplete, two openings b complete, one opening c two-way, one opening d one-way, two openings

The correct answer is: d, one-way, two openings.

The digestive system of arthropods begins with the opening in the mouth (where food enters the system) and it finishes with the anus (where food leaves the system). Because of that, it’s one-way.

Each arthropod has a different digestive system according to their method of feeding and body structure, but each of them has mouth opening and anus. Because of that, it’s two openings.
