Final answer:
Exoskeletons are external skeletons that must be periodically shed for the organism to grow, whereas endoskeletons are internal skeletons that grow with the organism and provide stronger support for larger body sizes.
Step-by-step explanation:
Comparing exoskeletons and endoskeletons, a true statement is that only endoskeletons can grow as an organism grows, while exoskeletons must be shed for growth. Exoskeletons are external skeletons found in invertebrates like arthropods and provide protection against predators. They are often made of materials like chitin and calcium carbonate. In contrast, an endoskeleton is an internal skeleton found in vertebrates and is made of bone or cartilage that allows for continual growth and support for larger body sizes. An endoskeleton provides stronger support and protection for internal organs, and the attachment of muscles on the outside of the bones provides better mechanical leverage for movement.
The correct statement comparing exoskeletons and endoskeletons is d) Exoskeletons grow with the organism, while endoskeletons must be shed for growth.An exoskeleton is an external skeleton that provides defense against predators and supports the body, while endoskeletons are internal skeletons made of bone or cartilage that allow growth and provide more protection for internal organs. Exoskeletons, such as the shells of crabs and insects, are made of chitin and must be shed periodically as the organism grows, while endoskeletons can grow along with the organism, supporting larger sizes.
