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.
This phylum is closely related to the chordates because the coelom of the animal is made from the digestive tube, not from cell masses like the phyla Mollusca, Annelida, and Arthropoda. Therefore, echinoderms are deuterosomes.
