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.
Protostomes include animals including Platyhelminthes, Molluscs, Arthropods, Annelids, Nematodes, and many other lower phyla. Among most of the protostomes, the coelom is formed via splitting a solid mass of the embryonic mesoderm; hence, they are called as schizocoelomates.herefore, it could be concluded that animals in the most developed or evolved phyla in the Animal Kingdom are the deuterostomes. When these two phyla are considered, one (Echinodermata) belongs to the group of invertebrates.
