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, or solid carbon dioxide, is the solid state of CO 2 gas below -109.3 Â°F (-78.5 Â°C). Dry ice does not occur naturally on earth but is man made. It is colorless. We can use dry ice for making drinks fizzy, killing gophers, and freezing warts. The vapor of dry ice causes suffocation and eventually, death.
