4. False - the shell of mollusks are maintained by the mantle

5. True

6. True ( they also help other organisms, not just earthworms)

7. False - the nephridia is used as a kidney

8. True

9. False - they are a pair of appendages

10. True

11. False - (I think so, but I could be wrong)

12. False - (again I think so but I could be wrong)
