2 Grade 11 Biology A/B Revision Work Sheet Modified True/False Indicate whether the statement is true or false. If false, change the identified word or phrase to make the statement true. 1. Why questions address the evolution of behavior. 2. Inherited behaviors are not modified by experience. 3. Over time, traits that provide a survival advantage become less common. 4. Natural selection favors traits that improve the likelihood that an individual will survive and reproduce. 5. In classical conditioning, the animal associates a related response with a stimulus. 6. Defensive behavior is a strategy for locating, obtaining, and consuming food. 7. Monarch butterflies that fly thousands of kilometers to breed are displaying migratory behavior. 8. Each species has a unique set of courtship signals. 9. Sexual selection influences the evolution of species. Multiple Choice Identify the choice that best completes the statement or answers the question.

3 1. Which behavior provides an answer to a why question? a. Birds sing by pushing air through the vocal cords. b. Bird sing in treetops. c. Birds sing to attract mates. d. Birds sing in the morning. 2. Which behavior provides an answer to a how question? a. Birds sing to attract mates. c. Birds sing to defend territories. b. Birds sing in treetops. d. Birds sing to protect their young. 3. Natural selection favors traits that benefit the a. species. c. group. b. individual. d. order. 4. Innate animal behaviors are primarily influenced by a. genes. c. reasoning. b. age. d. experience. 5. Trial-and-error learning is also called a. classical conditioning. c. imprinting. b. operant conditioning. d. habituation. 6. Learning that occurs only during a specific period early in an animal s life is called a. operant. c. reasoning. b. classical. d. imprinting. 7. Learned animal behaviors are primarily influenced by a. genes. c. reasoning.

4 b. age. d. experience. 8. In classical conditioning, a. a related response is associated with a stimulus. b. a related stimulus is associated with a response. c. an unrelated response is associated with a stimulus. d. animals learn by trial and error. 9. When Konrad Lorenz raised a group of newly hatched goslings, the goslings showed a. operant conditioning. c. imprinting. b. reasoning. d. classic conditioning. 10. Pavlov : classical conditioning :: a. dog : meat powder c. rat : box b. trial : error d. Lorenz : imprinting 11. Behavior in which animals locate, obtain, and consume food is called a. foraging behavior. c. migratory behavior. b. territorial behavior. d. circadian rhythm. 12. The hognose snake that flips onto its back and pretends to be dead is displaying a. foraging behavior. c. social behavior. b. territorial behavior. d. antipredator behavior. 13. Which of the following is not an example of an animal signal? a. sound c. movement b. posture d. migration

5 14. Animal signals have been shaped by a. photoperiod. c. classical conditioning. b. natural selection. d. reasoning. 15. The purpose of animal signals is to a. stimulate a response in another animal. b. obtain food. c. travel to a more suitable environment. d. learn a new behavior. 16. Which behavior is most likely to have evolved through sexual selection? a. running ability in a cheetah c. flying to Mexico for the winter b. singing ability in a robin d. playing dead when threatened Completion Complete each statement. 1. A(n) is an action performed in response to a stimulus. 2. Investigations into the circumstance that trigger a specific behavior are usually outlined in questions. 3. Evolution by natural selection is a process by which change in response to their environment.

6 4. Behaviors that do not stop once they have begun and have little variation are. 5. Inherited behavior may be called behavior. 6. is the development of behaviors through experience. 7. The ability to analyze a problem and think of a possible solution is called. 8. Behavior that can be learned only during a specific period in an animal s life and that remains fixed once it is learned is called. 9. Dogs that salivate in response to a bell have probably undergone conditioning. 10. behavior is observed in many bird species that have regular seasonal movements. 11. Animals use signals to with other animals. 12. A cat rubbing her face against a fencepost to leave her scent is using to signal her presence. 13. When animals mate based on the presence of desirable traits, they are demonstrating. Short Answer 1. In the following example, identify the stimulus and the response: A rattlesnake strikes at a lizard running across its path. 2. Identify two external factors that influence behavior. 3. What is meant by the term innate behavior?

7 4. What are two types of associative learning? 5. How are classical conditioning and operant conditioning different from each other? 6. Distinguish between specialists and generalists in terms of foraging behavior. 7. How is hibernation adaptive? 8. Compare and contrast nocturnal and diurnal behavior. 9. What are two purposes of courtship behavior? 10. Why would it be advantageous for predators to learn the courtship signals of their prey? Essay 1. Explain how a behavior such as the killing of cubs by male lions can arise through natural selection. 2. Explain how spider-web building is a fixed action pattern. 3. Explain how singing in humans is a behavior that exhibits both genetic and learned components. 4. Imprinting is adaptive because a duckling is fed and protected by the first object it sees usually its mother. How is having a short sensitive period for imprinting adaptive? Consider the consequences if the first object a duckling sees is another species. Explain how imprinting on this other species would be maladaptive.

8 5. Natural selection has shaped animal signals so that they reach the intended receiver effectively. Based on this, explain what kinds of signals would be most effective and least effective in a dense forest with limited visibility. 6. Using examples, describe four kinds of communication signals that animals use to influence behavior.
