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.
Some snails lay eggs but others have babies like we do, giving birth to live baby snails. Baby snails have tiny shells, but they are so weak, you can see through it. So the baby snail immediately starts huntingâ¦..for calcium (hmm not that tasty).hese shells are called âprotoconchesâ. Just like humans need loads of calcium to make our bones strong, baby snails need to eat loads of calcium to strengthen their shells. The first thing they tend to do when theyâre born is eat the egg they hatched from.
