Example: when I enter a number of minutes, I want it to automatically divide by 60 so I get an hour and minutes decimal... I think your math is a bit off. In Excel a day is equal to 1 and there are 1440 minutes in a day.
Characteristics of Mollusks. Mollusks are soft-bodied invertebrates with bilateral symmetry and usually one or two shells. Their organs are in a fluid-filled cavity; the word mollusks in Latin means soft. Most of the mollusks live in water but some live on land.
In general, mollusks have a soft body with a discernible head and foot region, and a hard exoskeleton in the form of a shell or plate. Mollusks are ubiquitous in both marine and terrestrial environments, and range in size from smaller than one millimeter to twenty meters long. There are eight classes in the phylum Mollusca. The focus of this discussion is on three of the five classes in the subphylum Conchifera, or shell-bearing mollusks. Three classes in Conchifera with an important presence in the Gulf of Mexico are Gastropoda, Cephalopoda, and Bivalvia.
