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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
