Answers to End-of-Chapter Questions by Richard W. Hill to accompany Animal Physiology, Third Edition Hill • Wyse • Anderson Chapter 10: Thermal Relations 1. As discussed in Chapter 1 (see page 11), Claude Bernard, a nineteenth-century French physiologist often considered the father of modern animal physiology, is still remembered today for his famous dictum: “Constancy of the internal environment is the condition for free life.” Does the study of thermal relations lend support to his dictum? Explain. 2. There is currently a worldwide movement to create protected marine parks. If the parks have an Achilles heel, it is that they have fixed geographical positions, just in the way that Yellowstone National Park is at a fixed geographical location. Suppose that a certain endangered species of fish exists only in a marine park. If the ocean temperature rises in the park because of global warming, explain what physiological problems the species of fish might confront. How might the species face a brighter future if parks could have moveable boundaries rather than fixed ones? 3. Referring to Figure 10.11, suppose you have some lizards that are at 16°C and have been living at that temperature for 5 weeks. What is their resting metabolic rate? If the lizards are suddenly shifted to a room at 33°C, trace on the graph how their metabolic rate will change from the moment they are placed in the new room until 5 weeks have passed. According to the graph, will they exhibit compensation? © 2012 Sinauer Associates, Inc.
