- 5. Multiple ChoiceThe similarities of the bones in the diagram provide evidence that---The organisms shown lived in the same natural envionrmentThe organisms shown may have developed from a common ancestorThe organisms shown have the same genetic diseasesAll vertebrate species have identical forelimbs

- 9. Multiple ChoiceChanges in species that allow that species to survive changes in the environment are called:ecosystemsadaptationsbiomesalleles
- 10. Multiple ChoiceIf an organism has a vestigial structure, that structure likely once had a function in a(n)close relativeearly ancestorunrelated organismembryological stage
- 11. Multiple ChoiceWhales are aquatic mammals that contain a pelvis bone. Even though it does not aid in its movement, the function must have been used by a common ancestor of the whale. Thus, the pelvis is referred to as a(n)vestigial structureanalogous structurehomologous structure
- 12. Multiple ChoiceMutations are important because they bring aboutdeath of the organism in which they developgenetic variation needed for a population to evolvebenefits for the individual, not for the populationHardey-Weinberg equilibrium within a population
