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.
The majority of species in this phylum are marine, benthic, or littoral animals, known from intertidal to deep sea environments. A few are terrestrial or ectoparasitic (mainly species in suborder Monostilifera), and around 20 species are found in freshwater environments.hylum Nemertea, or ribbon worms, contains approximately 1,200 species of bilaterally symmetrical, coelomate, unsegmented worms, which are divided into two classes, each of which is divided into two orders (Anopla: Palaeonemertea, Heteronemertea and Enopla: Hoplonemertea, Bdellonemertea).
