Land snails and slugs produce mucus, but so does every other kind of gastropod, from marine, freshwater and terrestrial habitats. The reproductive system of gastropods also produces mucus internally from special glands.
Dry ice was discovered rather than invented. It was first discovered by Charles Thilorier a French chemist in 1834. Check link below for more information on dry ice and dry i â¦ ce makers.
Hazards of Dry Ice. Dry ice is the solid form of carbon dioxide. It is non-combustible and is available in flakes, pellets, or block form. Dry ice will sublime (vaporizes directly to the gas state) at a temperature of -78.5 C (-109.3 F) or higher. Dry ice is commonly used to cool reactions or to ship biological specimens. Dry ice is considered hazardous three reasons: 1  Explosion hazard: dry ice releases a large volume of carbon dioxide gas as it sublimates. 2  Suffocation hazard: a large volume of carbon dioxide gas emitted in a confined space, or other unventilated area (e.g. cold room) may create an oxygen deficient atmosphere.
