In which of the following situations is biodiversity in a population likely to decrease over time causing a genetic bottleneck?A.Two new individuals of deer join an existing deer population.B.A storm kills 75 percent of a population of a species of a bird population in an area.C.A neutral mutation occurs in an individual of a population.D.A tree falls in a forest disrupting the habitat of several squirrels.

Endangered species are those that have rapidly declining populations. These species face extinction unless conditions change. In some cases conservation efforts are successful, and an endangered species begins to recover its population size.How does the bottleneck effect impact these species?A.It leads to increased rates of mutation in the recovering population.B.It causes speciation to occur in the recovering population.C.It results in reduced genetic diversity in the recovering population.D.It prevents natural selection from acting on the recovering population.

A scientist is studying two populations of the same species of birds - one in Michigan and one in Montana. Both populations are relatively large (with more than 10,000 individuals each). However, the Michigan population has a much lower genetic diversity than the Montana population. Which of the following accurately describes these two populations?Multiple choice question.The Michigan population likely experienced a bottleneck in the past. Both populations are equally susceptible to genetic drift.The Montana population likely experienced a bottleneck in the past. The Michigan population is currently more susceptible to genetic drift.The Michigan population likely experienced a bottleneck in the past and is currently more susceptible to genetic drift.The Montana population likely experienced a bottleneck in the past and it is also more susceptible to genetic drift.

Which of these conditions should completely prevent the occurrence of natural selection in a population over time?Group of answer choicesThe environment is changing at a relatively slow rate.All variation between individuals is due only to environmental factors.The population lives in a habitat where there are no competing species present.The population size is large.

Which of the following scenarios would NOT result in genetic flow?Select one:a.A population of deer with thick coats lives in a colder northern climate. Due to high habitat loss, these deer migrate south and successfully mate with another population of deer with thinner fur coats.b.Pollen from a population of white poppies is spread to a population of orange poppies by hummingbirds that drink the nectar from both poppy populations.c.A species of green beetles is in an agricultural cargo shipment and is relocated to a new habitat to thrive.d.A population of finches on the mainland interbreeds with the population of finches on

A small population of lizards on an isolated island experiences a severe storm that drastically reduces its size. Over time, the genetic variation in this population decreases significantly. Which of the following best explains this scenario?Question 5Answera.Gene Flowb.Founder Effectc.Bottleneck Effectd.Natural Selection
