The minimum age to obtain one's driverâs license should not be raised to 18 because 16-year-olds have a much more focused mind. If you change the minimum driving age to 18, it will be very little different from 16-year-olds because either way they wouldn't have very much driving experience.
Snails make their own shells.They make it with a muscle called the mantle.The mantle then releases liquid.When the liquid hardens it forms the shell.Later in the snails life t â¦ he mantle releases more liquid and the shell becomes bigger.
Snails are born with a small, soft, colorless shell called a protoconch, which then grows as the snail grows. Since snail shells are made up mostly of calcium carbonate, snails tend to have a very calcium-rich diet.Of interest, Stomatella snails are often mistaken for snails that are out of their shells, since Stomatella snails have transparent shells.owever, it can happen by accident, which usually leads to the snail dying. It's thought to be possible that some snails could live without their shells, until they form a new one, but this is considered unlikely.
