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.
In this experiment, students will find out whether dry ice will cool a beverage faster than wet ice. Regular wet ice is created when water is frozen and turns from a liquid to a solid. Dry ice, on the other hand, is not water at all. It is solid carbon dioxide. However, like water, it is also colorless and odorless--and dry ice will cool your drink just like wet ice. In this experiment, we'll discover which does the job fastest.
