Question

1.
are tiny hair-like bristles present under the body of the
earthworm.​

Answer 1

Answer:

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. ... In some cases, setae are modified into scale like structures.
