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.
Dry ice is the solid form of carbon dioxide (CO2). It's called dry ice because it does not melt like wet ice. Instead, dry ice converts into carbon dioxide gas. Because dry ice is extremely cold ( -109Â°F/-78.5Â°C), non-toxic, and completely dry, it is commonly used as an expendable refrigerant to ship frozen food or medical products or to cool materials during production.
