- Q1What is natural selection?A process by which organisms can choose their traitsA process by which organisms with disadvantageous traits are more likely to survive and reproduceA process by which organisms with advantageous traits are more likely to survive and reproduceA process by which organisms randomly change over time30s
- Q2What is genetic drift?A process by which organisms randomly change over timeA process by which organisms choose their mates based on their genesA process by which organisms deliberately change their genesA process by which chance events cause changes in allele frequencies in a population30s
- Q3What is gene flow?The process by which new mutations arise in a populationThe transfer of genetic information between populationsThe process by which organisms adapt to their environmentThe process by which organisms randomly change over time30s
- Q4What are mutations?Changes in an organism's behaviorChanges in DNA sequences that can be inherited by offspringChanges in an individual's physical traits over timeChanges in an organism's habitat30s
- Q5Which of the following is not a mechanism of evolution?Habitat destructionGene flowNatural selectionGenetic drift30s
- Q6Which of the following best describes genetic drift?The transfer of genetic information between populationsThe process by which organisms adapt to their environmentThe process by which mutations ariseRandom changes in allele frequencies in a population30s
- Q7Which of the following is an example of natural selection?A population of birds deliberately selecting mates with longer beaksA population of birds with longer beaks surviving better during a droughtA population of birds randomly changing their beak shapeA population of birds losing their beaks over time30s
- Q8Which of the following is not a source of genetic variation?RecombinationEnvironmental factorsGene flowMutation30s
- Q9Which of the following is an example of gene flow?A migratory bird species bringing new alleles to a populationA population experiencing a bottleneck eventA population becoming isolated from othersA mutation occurring in a population30s
- Q10Which of the following is not a result of evolution?PerfectionAdaptationExtinctionDiversity30s
