Answer:

Step-by-step explanation:

Your lab group is charged with the identification of an unknown creature. Your lab partners believe that is a small annelid because of its worm like appearance. You argue it is a nematode. To convince your lab partners, you point out certain distinguishing characteristics. Check the characteristics that are associated with the annelids.

Nematodes secrete a cuticle, which is made primarily of collagen; Internal fertilization;Nematodes are cylindrical but not segmented;Their pseudocoelom functions both as a circulatory system and a hydrostatic skeleton

Nematodes lack true body cavity but possess a pseudo-coelom body cavity unlike annelid
