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.
Storage instructions. 1  Dry Ice will sublimate into Carbon Dioxide (CO2) gas. 2  Store Dry Ice in an insulated container-the better the insulation, the slower the Dry Ice sublimation. 3  Do not store Dry Ice in a refrigerator or a freezer (unless the Dry Ice is being used to maintain the proper holding temperature).
