Annelids, unlike roundworms (or flatworms for that matter) are segmented. That is after all how they get their name (annelida = little ring). Annelids also have a very complex organ system.Roundworms only possess a reproduction system as they usually live in an organism's intestines and don't need to digest food.nnelids, unlike roundworms (or flatworms for that matter) are segmented.

A good quality GMRS radio, or a commercial radio programmed to use GMRS frequencies, can probably get a range of about five miles or so. A good base or repeater, with a good antenna mounted high off the ground should be able to get a range of 15 to 25 miles.
I should also say something about the Multiple Use Radio Service-MURS. This is an often overlooked service with lots of potential. Unlike the UHF GMRS/FRS (similar to the amateur 70 cm band), MURS is a VHF service, similar to the amateur 2 meter service. MURS radios are permitted up to 2 watts of power, and can use antennas which provide gain. The approximate frequency range of MURS is 150Mhz to 155Mhz on five channels.
