All of the options listed are differences between a gastrovascular cavity and a complete digestive tract. A gastrovascular cavity has only one opening that serves as both the mouth and the anus, whereas a complete digestive tract has two openings. The complete digestive process is faster in a complete digestive tract, as there is more specialization of parts, and the four functions of digestion (ingestion, digestion, absorption, and elimination) occur simultaneously.
