- 1. Multiple Choice
Which of these would you most expect to be true if these organisms were classified by their physical characteristics?Organisms 1 & 3 are more closely related than 2 & 4Organisms 1 & 3 are in the same speciesOrganisms 2 & 4 are more closely related than 1 & 3Organisms 2 & 4 are in the same species - 2. Multiple ChoiceWhich of these scenarios is an example of natural selection?Giraffes with longer necks survive a dry season by eating leaves from the tops of trees and they breed more successfully that yearPeople kill rattlesnakes that rattle when approached by humans, but people do not kill rattlesnakes that remain silent. The quiet snakes survive and breed.Dogs of the same breed and having desirable coat color are bred with one another to produce more puppies with that same colorFarmers crossbreed two types of cows to produce a breed of cow that has high-quality beef and can tolerate a hot climate
- 3. Multiple ChoiceSamantha plans an investigation in which she will study a population of animals. Which of these answers best describes the focus of Samantha's study?a single cat that lives in her housethe cats and dogs at a local animal shelterall the cats in her neighborhoodall of the pets owned by her classmates
- 4. Multiple ChoiceTwo species might have similar skeletal structures that have different functions. What do these types of structures suggest about the relationship between the two species?common sructures with different functions suggest that the species do not share a common ancestorcommon sructures with different functions suggest that the species share a common ancestor that also have a similar structurecommon sructures with different functions suggest that one of the species never learned how to use the structure properlycommon sructures with different functions suggest that the species live in the same habitat
- 5. Multiple ChoiceDarwin found that beaks of finches in the Galapagos varied in shape and size. If they ate mostly insects, they had long, narrow beaks and if they ate seeds they had broad beaks to crush the seeds. Which statement best describes natural selection in the 4 types shown?broad-beaked finches wore down their beaks digging for insects and passed these narrower beaks onto their offspringnarrow-beaked finches came first and evolved into the broad-beaked finches through a series of natural mutationsover time, the finches that were born with beaks better suited to the available food supply in their habitats survived and reproducedthe residents of the Galapagos Islands selectively bred together finches having the trait that they wanted them to have

- 8. Multiple ChoiceWhich inference is best supported by these images? Assume that each finch comes from a large population of similar finches in its particular environment.Finch 1 lives in an environment with few finches and many insects and many seeds with hard shells; Finch 2 lives in an environment with many small insects and few seedsFinch 1 lives in an environment that is warmer and drier than the environment in which Finch 2 livesFinch 1 lives in an environment that is colder and wetter than the environment in which Finch 2 livesFinch 1 lives in an environment with many small insects and few seeds; Finch 2 lives in an environment with few insects and many seeds with hard shells
