The average date of the first 1-inch snow (1 inch or more) is December 2. The greatest depth of snow on the ground was 19 inches on February 8-10, 1982. The greatest 24-hour snowfall was 15 inches on January 1-2, 1999. Temperature and precipitation records go back to 1888 for Champaign-Urbana.
The name annelidia derives from annellus, which means little ring in Latin. The body of annelids is divided into segments that are separated by septa, and in many annelids, bristles called satae are attached to each segment.
The basic approach is to come up with a basic body compartment, like cars on a train, and build up a body by adding more. It is a quick and simple way to add size, and segmented worms, also known as annelids, are the prototypes. The leeches are less segmented than the other types, although the basic body plan of the adult almost always starts with 34 segments between front and back (this is common in other segmented groups, where a set number of segments arises in embryos as the base architecture).
