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..
Advantages of having an exoskeleton include protection from predators and a sturdy body structure, while disadvantages include limited mobility and the requirement to molt in order to grow. However, having a backbone allows for greater flexibility and movement, along with the ability to grow continuously without molting.
Advantages of having an exoskeleton rather than a backbone include protection from external threats, support for agility and movement, and resistance to desiccation. Disadvantages include limited growth potential, decreased flexibility, and vulnerability during molting periods.
