Multiple Choice
Use the following information when answering the corresponding questions) .
Many terrestrial arthropods exchange gases with their environments by using tracheae, tubes that lead from openings called spiracles) in the animal's exoskeleton or cuticle directly to the animal's tissues. Some arthropods can control whether their spir opened or closed; opening the spiracles allows the carbon dioxide produced in the tissues to travel down the tracheae and be released outside the animal. Klok et al. measured the carbon dioxide emitted over time represented by VCO2) by several species of centipedes. Figure 31.2 presents graphs of their results for two species, Cormocephalus morsitans and Scutigerina weberi. C. J. Klok, R. D. Mercer, and S. L. Chown. 2002. Discontinuous gas- exchange in centipedes and its convergent evolution in tracheated arthropods.
