B. Observed modern extinction rates will resemble the rates found early in previous extinctions. Increasing the number of trials and the number of mice in each treatment group. C. After 1940, natural selection prevented any additional speed increases. A population geneticist is conducting an investigation on a population of mice. Which of the following best explains the mechanism that caused this speciation event in the giant kangaroo rats of population A? which of the following best provides evidence to support this claim? Which of the following predicts the expected outcome of the experiment? By the end of the twentieth century, the peppered version of the moth was again more common than the black version. C. Populations with little genetic diversity are less likely to contain individuals that can withstand different selective pressures. D. There is a progression of cellular organization in organisms found in Bacteria, Archaea, and Eukarya. C. The group of mice fed the mutagen will show a greater ability to digest the food, because the higher genetic variation within the group makes it more likely that some individuals will have a combination of genes better adapted to the new food. Continue treating the three insect populations with the same insecticides and determine whether their efficiencies decline significantly after several generations. A. John David Jackson, Patricia Meglich, Robert Mathis, Sean Valentine, PL-600: Microsoft Power Platform Solution Arc. Which of the following would be an appropriate alternative hypothesis? A shift to less polluting fuel in the twentieth led to cleaner air and a lightening of the moth's normal habitat. Based on the phylogenetic relationships shown in Figure 1, which of the following best explains the similarities exhibited by whales, bony fishes, and cartilaginous fishes? AP Biology AP Classroom Unit 7 FRQ Flashcards | Quizlet The species will undergo artificial selection, as the genes will adapt to warmer temperatures. A group of birds is found in an island chain that have all descended from a single ancestral species. B. A population of the species has the following allele frequencies: B=0.85 and b=0.15. Of the following, which is the best next step for the researchers to best determine the long-term effectiveness of these insecticides with regards to the development of resistance? The animals in population A were reproductively isolated from those in populations B, C, and D. Mollusk fossils were excavated and collected from a coastal cliff. Each of the fifteen genotypes shown in generation 1 and generation 2 represents 100 mice. WebIt is Monday morning, May 13, and you will be taking the AP Biology Exam. A. Which of the following best predicts why humans and mice have identical telomeric repeat sequences? Formation of crude proteins occurs by chance and occurs regardless of atmospheric O2O2 levels or available free energy. z=ycos(xy),(2,2,2)z=y \cos (x-y), \quad(2,2,2)z=ycos(xy),(2,2,2), Write the electron configuration of the ion. B. The presence of MC1Rd alleles in the East lava flow population is an indication of gene flow from mice populations living on light granite rocks. A group of scientists found that in one population the frequency of the M allele was 0.82, and the frequency of the N allele was 0.18. Which of the following statements best predicts the result of a comparison between the fossils found before and after the period of rapid change? If a fire caused the surface of the ground in the habitat of the species to become darker in color, which of the following claims about the impact on the allele frequencies in this population is most reasonable?
