Which statement about the tubular digestive tract of animals is true?

Question

Quizplus · Accepted Answer

Digestion in animals with a tubular digestive tract occurs within the tract itself, involving the breakdown of food into smaller, absorbable components. This process is primarily extracellular, contrasting with intracellular digestion. The tubular digestive tract typically has two openings (mouth and anus), allowing for a more efficient process of ingestion, digestion, and egestion. While mechanical breakdown of food into smaller pieces can aid in digestion, it is not a requirement for all animals, as some can ingest large pieces or even whole prey. The digestive tract is specialized along its length, with different sections adapted for specific functions (e.g., stomach for protein digestion, intestines for nutrient absorption), making it non-uniform.
