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.
The snail is a small to medium sized mollusc that is generally split into three groups which are land snails, sea snails and freshwater snails.nails that do not have a shell are not snails, but slugs. In order to break down their food, most snails have thousands of microscopic tooth-like structures located on a ribbon-like tongue called a radula.
