Answer:
(1) false
(2)true
Explanation:
(1) reason:No. The shell is present from the snail's early development, is attached to the snail, and grows along with the snail in a spiral shape. A snail can't crawl out of its shell any easier than you can walk away from your fingernails!
(2)reason:The cartilages are harder than bones. The finger bones do not have joints. The fore arm has two bones. Cockroaches have an outer skeleton.
