Biology Honors Prentice Hall Textbook by Miller/Levine Honors Biology 3/12/10 Chapter 28 HW 1. B 2. A 3. B 4. B 5. B 6. D 7. D 8. D 9. C 10. B 11. Tracheal tubes extend throughout the entire arthropod body, so each part has access to oxygen. Also, there are spiracles to release carbon dioxide all over the body. 12. Terrestrial arthropods dispose of nitrogenous wastes using Melpighinan tubules. In aquatic arthropods, diffusion move cellular wastes from the arthropod’s body into wastes. 13. The brain serves as a central switchboard that receives incoming information and then sends outgoing instruction to muscles. Two nerves that encircle the esophagus connect the brain to a ventral nerve cord, which contains several ganglia. These ganglia coordinate movements of individual legs, and compound eyes gather information from the environment. 14. The carapace is the part of the exoskeleton that covers the cephalothorax. 15. Unlike decapods, barnacles are sessile, meaning they are attached to a single spot. 16. A mandible is a mouth part adapted for biting and grinding food. 17. Chelicerae are a pair of appendages which contains fangs and rate used to paralyze prey. The other pair, called pedipalps, are longer than the chelicerae and grab prey. 18. Their chelicerae and pedipalps are specialized for digging into a host’s tissues and sucking out blood or plant fluids. In many species, the chelicerae are needlelike structures that are used to pierce the skin. The pedipalps are often equipped with claws of the host for attaching to the host. These mouthparts are so strange, that if a tick begins to feed on you and you try to pull it off, its cephalothorax will remain in your skin. 19. The number of legs is an obvious difference. Centipedes only contain one pair of legs per each segment. Millipedes contain two pairs of legs. 20. The characteristics of insects have contributed to their success because they have different ways of responding to stimuli, the evolution of flight, and a life cycle in which the young differ from adults in appearance and feeding methods. 21. The main adaptation for feeding in insects is the three different types of mouth parts. Some are sharp, some are tubelike, and some are spongelike. Many insects produce saliva
