- Which of the following statements best applies to the term adaptation? * A. Resistance increases as a result of exposure to prior stress B. Resistance decreases as a result of exposure to prior stress C. Genetically determined level of resistance acquired over generations D. Genetically determined level of resistance acquired in one generationarrow_forwardWhich of the following is an example of a behavioral adaptation? A. flamingo's feathers turn pink after eating crustaceans. B. A snowshoe hare turns white in the winter. C. A robin builds a nest out of sticks and dry grass. D. A Komodo dragon has a poisonous bite.arrow_forwardAnimals have evolved a range of strategies to successfully respond to threats and challenges. One of these strategies is the ability to learn. As we discussed, not every animal can learn and there are clear costs and benefits to this strategy. Suggest one benefit of the ability to learn and one potential cost. Briefly explain each. (1-2 sentences for each) Since learning is not universal, under which circumstances would it be most likely be a successful strategy? We discussed a framework that examines the influence of predictability on the success of learning ability. Describe this framework. Make sure you discuss all the available conditions and clearly state under which we would expect learning to be successful and where we would not expect it to be successful. What would be an alternative strategy to regulate behaviour when learning is not suitable? Briefly explain your choice. (2-3 sentences)arrow_forward
- A genetically inherited, complex pattern of behavior that always appears among members of a particular speciesunder appropriate environmental conditions is a(n)a. reflex.b. instinct.c. drive.d. needarrow_forwardClassify each of the following descriptions as either a proximate or anultimate cause of behavior. For all proximate causes, speculate about apossible ultimate cause of the behavior. a. A surge of epinephrine initiates a flight response in a gazelle.b. Turtles use Earth’s magnetic field lines as guides during migration.c. A small mammal ignores low-energy food sources that are difficultto obtain, maximizing energy gain from foraging.d. A bird distracts a predator near its nest, increasing the nestlings’chance of survival.arrow_forwardConventional signals are not costly because they often entail slight visible variations in only a small portion of the body, but they can be rendered honest through social reinforcement. Which example best demonstrates this case? A. Birds with large throat patches with poor fighting ability are attacked more often by dominant birds. B. Aggressive wasps with facial patterns indicating their fighting ability are less likely to be attacked. C. A dominant lion is able to evict younger chalengers from the pride. D. Female chimps will not mate with a male defeated in combat.arrow_forward

Natural selection works differently in humans than other animals. b. It is easy to test evolutionary hypotheses by doing experiments. c.Most social behaviors are genetically determined with little influence by the social environment. d.
