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.
Mollusks. Maybe you think that snails, clams, mussels, squid, and octopods are very different. Yet, they are all in the same category of animals known as mollusks and are structurally similar. Mollusks are some of the most well known of invertebrate sea creatures (there are over 50,000 species). Some are very rare and are only found in very deep-water. Mollusks have three body regions. 1. The head contains the brain and the sense organs. 2. The visceral mass contains the internal organs. 3. The foot is the muscular part of the body. Mollusks usually, but not always, have a shell, which is secreted by a body wall called the mantle. Many mollusks have a tongue of sorts, called a radula. The radula is rough like sandpaper. Mollusks have well developed body organs that are used in the respiratory, circulatory and nervous systems. The Stomach-Foot The stomach-foots (class Gastropoda) contains about 70% of all mollusk species.
