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.
As snails move in a specified direction, other than, for example, their relatives, the mussels and clams (Bivalvia), they also developed a head at the front end of the foot, with most of the snail's sense cells and organs, with tentacles and eyes.
