In the peppered moth example, what caused the population to evolve?Group of answer choicesa change in their predatorsthey just wanted to changea change in the environmenta change in their food choice

define natural selection and explain the peppered moth example

Which of the following statements best describes evolution taking place in the peppered moth population?Group of answer choicesA single moth changed itself from light to dark.All the members of the moth population changed their color from light to dark.The peppered moth population had more dark moths after several generations.The moths all died.

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

Explain how natural selection caused the frequency of black moths within the population to increase during the Industrial Revolution.

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.
