Correct answer: C. Parapodia and Setea
- A. Muscles and Bones
- B. Hydrostatic skeleton and intestinal fluid
- C. Parapodia and Setea
- D. None of the above.
Explanation
Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground.Annelid Parapodia are paired, unjointed lateral outgrowths that bear the chaetae.
