Convert time to seconds in Excel. Converting time to total seconds is done in the same fashion-you multiply the time value by 86400, which is the number of seconds in a day (24 hours * 60 minutes * 60 seconds = 86400):
Nematoda (nematodes, eelworms, threadworms, roundworms; phylum Aschelminthes) Class of aschelminth worms (a phylum in some classifications) which vary greatly in size, from about 1 mm to 5 cm. The cuticle has flanges, and may also have ridges or spines.
Annelids are considered members of the Lophotrochozoa, a super-phylum of protostomes that also includes molluscs, brachiopods, flatworms and nemerteans. The basic annelid form consists of multiple segments. Each segment has the same sets of organs and, in most polychates, has a pair of parapodia that many species use for locomotion. Septa separate the segments of many species, but are poorly defined or absent in others, and Echiura and Sipuncula show no obvious signs of segmentation.
