Lecture 2 objectives Topic: Animal form and function Reading: Chapter 41 End of chapter problems: TYK: 1-6, TYU: 1-4 1. Define an adaptation (natural selection, survival, reproduction). How does the structure of a trait relate to its function? Provide specific examples. 2. Define a fitness trade-off. Work through and be able to interpret the experiment on p. 915*. 3. Describe the difference between adaptation and acclimation.* 4. Describe the major tissue types in animals. 5. How does the surface area to volume ratio affect animal physiology? In what ways is this the same and different in plants? 6. Why does an elephant have a lower mass-specific metabolic rate than a mouse? 7. Give several examples of adaptations to increase surface area in tissues involved in the exchange of substances between animal and environment. Is this more important in large or small animals? Study the experiment on P. 923 as you consider your answer*. 8.
