- 1. Multiple ChoiceStructures that are inherited from a common ancestor are homologous.TrueFalse
- 2. Multiple ChoiceWhen would convergent evolution occur?When organisms share a common ancestorWhen organisms live in similar environmentsWhen organisms become increasingly differentWhen organisms experience a change in their environment

- 18. Multiple Choice
If an organism has a vestigial structure, that structure likely once had a function in a(n)close relativeearly ancestorunrelated organismembryological stage - 19. Multiple ChoiceSome organisms that share a common ancestor have features that have different functions, but similar structures. These are known asvestigial structuresanalogous structureshomologous structuresfossil structures
- 20. Multiple ChoiceTwo organisms that are closely related would havevery similar DNA sequenceexactly the same DNA sequencesno proteins in commoncompletely different DNA sequence
- 21. 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
