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.
You may have noticed that most of the consumer two-way radios you see around advertise a range of up to 30 miles. The truth is, consumer FRS/GMRS radios will not even provide close to the advertised maximum range. The range that a two-way radio advertises is the range that the radio should get in ideal conditions. Ideal conditions are line of sight, such as from a mountaintop to a valley below -- no interference at all.
