Which of the following is an example of frequency dependent selection? A change in the fitness of non-poisonous butterflies as a result of the numbers of poisonous ones in the population Improved mating of a male Prairie Chicken due to his behavioral display The rapid evolution of a bacteria due to its increased rate of mutation The reduction in a population of fish due to an oil spill

Voles of two different colors, brown and gray, live on the same island. Hawks find these voles to be their primary food source. The voles are distributed through grassy areas in the north of the island and across lava flows in the south part. Which of the following is predicted by natural selection? Hawks find the voles by movement so it won't matter. A vole population that starts as a random mixture will never adapt to the environment. Brown voles are good at hiding in the grass; gray voles are excellent at climbing over lava flows. Consequently, the vole distribution will reflect the ability of hawks to identify each of them in its natural environment. If they stay as a mixed population, they will remain mixed because the two varieties will not interbreed with each other. The hawk population will be skewed toward the north side of the island

A farmer wants to make a better corn plant that produces more and bigger kernels. In the chart, information is provided on two ways organisms can change over time. Natural Selection Selective Breeding Humans are not involved in the evolution process Human intervention is involved More generations are involved in natural selection, so it is a slower process Selective breeding is a faster process Survival of the fittest increases species' chance for survival Adaptations may not necessarily improve survival Mutations that result in natural selection occur randomly The desirable charactenstics are artificially chosen What is the best way for the farmer to improve his crop and why? Use evidence from the table to support your reasoning. Please write in complete sentences.

Which of the following are factors that can impact genetic variation in a population? (Select all that apply.) Lack of natural selection Random mating Mutation | Migration

In which population is evolution by natural selection most clearly demonstrated? Group of answer choices A virus sweeps through a population and makes everyone ill.  A virus sweeps through a population and kills 10% of infants. It is not clear why some die and some don't. A virus sweeps through a population and kills 20% of the population. It is not clear why some die and some don't. A virus sweeps through a population and permanently sterilizes the 10% of the population that has allele hx25c.

Which type of selection best describes the shift in peppered moth from the light form to the dark form following the industrial revolution? Directional Stabilizing Disruptive 58

Imagine a group of adventurous people board a boat and leave for another continent. When they get there, they began to prosper and grow in size. After a few generations, some of the families experience an abnormally high number of birth defects, of the same type. This population is probably experiencing: O Kin Selection Founder Effect O Natural Selection O Post-Zygotic Isolation
