Answer 2

Answer:

Earthworms (annelids) have slightly more evolved excretory structures called nephridia, illustrated in Figure 22.10b. A pair of nephridia is present on each segment of the earthworm. They are similar to flame cells in that they have a tubule with cilia. Excretion occurs through a pore called the nephridiopore.
