- 1. Multiple ChoiceThe theory of natural selection was a hypothesis first proposed byGregor MendelJames Waston and Francis CrickCharles DarwinRobert Hooke
- 2. Multiple Choice1000 red and 1000 white ground beetles are placed in a cage on red clay containing beetle eating birds. The beetles are counted after 2 days. What is expected?Equal number of red and white beetles are leftMore red beetles are leftMore white beetles are left.All the beetles are gone.
- 3. Multiple ChoiceDarwin's studies of finches on the Galapagos Island suggests that the finches' differences in beak structure were most directly due to:acquired characteristics in the parent finchesthe size of the island where the finches live.mating behaviors of the different finch speciesgeographic isolation and adaptations of the finches to different environments
- 4. Multiple ChoiceWhich statement best describes evolution.evolution is a predictable change from simple to complex organismsevolution is a process of change through timeevolution causes organisms to develop characteristics they needevolution often proceeds from complex to simpler organisms.
- 5. Multiple ChoiceCharacteristics of a species that make its members better able to live and reproduce in their environment are known asabiotic factorsbiotic factorshomologous structuresfavorable adaptations.
- 6. Multiple ChoiceWhich of the following is true about natural selection?a population of organisms of the same species are all alikeorganisms posses genetic characteristics that sometimes make no difference on their livesorganisms choose characteristics that help them adapt to their environmentonly those organisms that survive the environmental change pass on their traits to the next generation
- 7. Multiple ChoiceMany scientists believe that the great number of different species of organisms which exist on the planet and the present time has resulted from billions of years ofgel electrophoresisrecombinant DNAcloningevolution
- 8. Multiple ChoiceA change in the gene pool due to death or isolation is callednatural selectionbiochemistrygenetic driftmutations
- 9. Multiple Choice
The information in the chart provides data that can help in the identification of possible evolutionary relationships from the study of comparative __________cytologyembryologyanatomybiochemistry - 10. Multiple ChoiceUsing the information from the chart, which two organisms are the closest in evolutionary distance from a common ancestor?horse-zebrahuman-gorillahuman-chimpanzeehorse-chimpanzee
- 11. Multiple ChoiceA large population of bluejays living in the mountains is separated by the formation of a desert. After millions of years, the populations of bluejays would most likely...become exstinctdiverge into two new speciesevolve into catsbecome two very small populations of the same species.
- 12. Multiple ChoiceHow are sudden changes and gaps in the fossil record explained?natural selectionpunctuated equilibriumacquired characteristicsDNA evidence
- 13. Multiple ChoiceThe diagram shows undisturbed sedimentary strata at the bottom of the ocean. The fossils found in layer B resemble the fossils found in layer A. This similarity suggests that.modern forms of life lay have evolved from earlier forms of lifevertebrate fossils are only found in sedimentsthe fossils in layer A must be more complex than those in layer Bthe fossils in layers B were formed before the fossils in layer A
- 14. Multiple ChoiceThe diagram below shows the gradual change over time in the anatomy of the horse. Which concept is best illustrated by the physical variations in the horse as its body size and structure change over time?acquired characteristicsartificial selectionintermediate inheritanceevolution
- 15. Multiple ChoiceFossils of an extinct species of giant armadillo were found to be similar to a smaller species of armadillo presently inhabiting the same region. This similarity could best be explained on the basis of...evolution from older formsuse and disuseinheritance of acquired traitsthe heterotroph hypothesis
- 16. Multiple ChoiceA study of the position and shape of the bones in the forelimbs of a flying squirrel, a bat, and a beaver showed that the beaver and the flying squirrel appear to be most closely related. This determination was most likely based on a study in the field of comparativeanatomybiochemistycytologyembryology.
- 17. Multiple ChoiceFossils would most likely be found inamber (petrified sap) that is over 8 billion years oldicebergs that are 500 billion years oldsedimentary rocks that are 500 million years oldvolcanic rocks that are 50 million years old
- 18. Multiple ChoiceThe diagrams below represent homologous structures. The study of the evolutionary relationships between these structures is known as comparative...embryologyanatomybiochemistrycytology
- 19. Multiple ChoiceThe diagram shows a comparison of base sequences in the DNA of some organisms to those of a human. According to this diagram, humans and gorillas last shared a common ancestor how many million of years?5 million years ago8 million years ago15 million years agothe present
- 20. Multiple ChoiceBlood proteins in horses are chemically similar to blood proteins in moneys. This similarity suggests that horses and monkeyscan interbreedevolved at the same timelive in the same habitathave a common ancestor
- 21. Multiple ChoiceThe diagram below represent stages in the embryonic development of four organisms. The similarities in embryonic development shown in the diagram suggests that these oranismsall undergo external developmenthave adaptations for the same enviromentare all members of the same speciesmay have evolved from a common ancestor
- 22. Multiple ChoiceThe diagrams show embryos of three different vertebrate species. According to one theory, similarities in these embryos suggest common ancestry. As these embryos matures, they will most likelydevelop new organs according to the nutritional requirements of each organismsshow no similaritiescontinue to closely resemble each other as adultsdevelop distinctive characteristics of their species
- 23. Multiple ChoiceThe Hardy-Weinberg equilibrium equation (p2 + 2pq + q2 = 1) allows geneticists to:keep track of changes in phenotype frequencies from generation to generation in small familieskeep track of changes in phenotype frequencies from generation to generation in a populationdetermine what evolutionary mechanisms are causing changes in a population's gene pool frequenciesLet Mr. Pennell teach basic algebra to unsuspecting bio students
