A)gastrovascular activity, two-layered body, and torpedo shape.
B)external respiratory surface, small size, and two-layered body.
C)large volume, long tubular body, and wings.
D)complex internal structures, small size, and large surface area.
E)unbranched internal surface, small size, and thick covering.

Question

Quizplus · Accepted Answer

Animals with external respiratory surfaces such as gills or lungs are able to efficiently exchange gases with the environment. Small size allows for a large surface area to volume ratio, increasing the rate of exchange. A two-layered body allows for a simple diffusion of gases and nutrients across the body surface.
