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 phylum is Platyhelmenthus   The three classes are   1. turbellaria   2. trematoda   3. cestoda   Platyhelminthes is a phylum composed of three classes of fl â¦ atworms. Members of the phylum Platyhelminthes are dorsoventrally flattened   with a triploblastic body composed of three different tissue layers:   ectoderm, endoderm, and the mesoderm. These animals are bilaterally   symmetrical, meaning that a slice directly through the middle can produce   two mirror images.
