Answer 1

Answer:

In earthworms, members of the phylum Annelida, the excretory system consists of structural units called nephridia. The nephridium is an invertebrate organ which occurs in pairs and performs a function similar to the vertebrate kidney. Nephridia remove metabolic wastes from an animal's body. Cockroach belongs to class Arthropoda because it has jointed appendages and the hard exoskeleton. Crocodiles are reptiles, not amphibians because they lay their eggs on the land, not in the water.
