D) exoskeleton.
E) vascular canal.

Accepted Answer

An endoskeleton is an internal support structure found in organisms such as humans, fish, and reptiles. It provides support and protection for internal organs. A hydrostatic skeleton, on the other hand, is a fluid-filled cavity that provides support and movement in organisms like jellyfish and worms. A gastrovascular cavity is a cavity in certain animal phyla that functions in both digestion and circulation. An exoskeleton is an external hard structure found in organisms like insects and crustaceans. A vascular canal is a pathway through which nutrients and fluids travel within a plant.
