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 invertebrates, which are animals with no backbones. The shell on the snail helps protect it, and also reduces the loss of water by evaporation. Shells have many different shapes, sizes, and colours. Snails do not breathe through their mouths, instead they have a breathing hole under their shells.
