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.
Privacy codes (CTCSS) are also compatible on all Midland GMRS and FRS radio models capable of this feature. Each radio must be set to the same channel and CTCSS code for the radios to communicate with each other. GMRS radio has a range of up to 5 miles or more. The range is relative to the obstacles around you. On an open field, or water the range is greater. Urban development may reduce the range to 2 miles or less. If you are in a tall building the range is about 20 floors. This is very common with two-way radios.
