Question

Snails and beetles have exoskeletons. Hypothesize the advantages and disadvantages of having an exoskeleton rather than a backbone. Explain your answer in one or two sentences.(2 points)

Answer 1

Advantages of having an exoskeleton include protection from predators and mechanical support, while disadvantages include limited flexibility and the need to molt in order to grow. Backbone structures allow for greater flexibility but may not provide as much protection.
