It ensures that all nutrients are absorbed in the mouth, making the rest of the digestive tract unnecessary.

Answer 1

The correct response is:

It allows for a one-way flow of food, preventing waste from being reabsorbed and ensuring complete digestion and elimination.

This structure enables both humans and frogs to efficiently digest food as it moves through the digestive tract, allowing for mechanical and chemical breakdown at various stages while preventing any backflow that could lead to reabsorption of waste.
