The peppered moth is often used as a case study to illustrate natural selection.  The allele for dark-colored is dominant and the allele for light colored is recessive.  In the 1850's light-colored moths were higher in population size and easily camouflaged in the trees from predators; however after industrial air pollution covered the trees with soot in the early 1900's the dark-colored moths blended in with the trees more effectively and became greater in number than the light-colored moths.  Which evolutionary trend is demonstrated?Group of answer choicesa smaller percentage of light-colored moths survive to reproduce, shrinking the gene pool and causing mutations.the populations of the light-colored and the dark-colored moths will both become extinct.more dark-colored moths survive to reproduce, which shifted the allele frequency towards the dark-colored allele.over time, the birds will get used to eating the light-colored moths and stop eating the dark-colored moths.

During the Industrial Revolution, black peppered moths had better camouflage than white moths. Over many generations, black moths became very common in the population.What was the selection pressure:*1 pointPredators hunting more white moths than black moths.Predators hunting more black moths than white moths.Camouflage increased the frequency of the black colour trait in the population.Camouflage increased the frequency of the white colour trait in the population.

During the Industrial Revolution, black peppered moths had better camouflage than white moths. Over many generations, black moths became very common in the population.

Why did the black peppered moth become more prevalent than the white peppered moth during the industrial revolution?The white peppered moth was killed by pollutionThe black peppered moth could fly faster and therefore escape predatorsThe black peppered moth ate the white peppered mothThe black peppered moth was better camouflaged against polluted tree bark

The data indicates that during the Industrial Revolution, dark mothsElimination ToolSelect one answerAhad a higher survival rate than light moths.Bcould change color.Chad greater genetic variation than light moths.Dcould change their phenotype.

Which of the following is natural selection?When a pregnancy is terminatedWhen animals or plants are bred by humans to produce desired characteristicsWhen humans adapt to their environment, e.g. by wearing clothes for warmthWhen a mutation in an organism that makes it better suited to its environment is passed on to the next generation2Why did the black peppered moth become more prevalent than the white peppered moth during the industrial revolution?The black peppered moth ate the white peppered mothThe black peppered moth could fly faster and therefore escape predatorsThe black peppered moth was better camouflaged against polluted tree barkThe white peppered moth was killed by pollution3Natural selection within a species occurs when advantageous genetic mutations are passed on to the next generation. Which of the following is the best explanation for why this happens?Mutations cause changes in the environment that make breeding more successfulThe mutation can be passed from individual to individual by pathogensIndividuals with the mutation can escape predators more easilyIndividuals with the mutation are more likely to survive and breed successfully 4Why can bacteria evolve more quickly than other species?They are simple unicellular organismsThey reproduce at a fast rateThey are resistant to antibioticsThey have been around for millions of years
