Ap Bio: Unit 7 Progress Check: MCQ Flashcards | Quizlet Humans and mice share a recent common ancestor that had the 5-TTAGGG-3 repeat sequence in its telomeres. 2023 AP Bio Unit 7 Review | Free Reviews, Study Guides, & Notes Which of the following best predicts the effect of the enclosure on the O'Neill population? WebA. B. Bacterial ribosomes cannot recognize eukaryotic mRNA and will not translate the codon sequence. C. Dark color is selected for in mice from the West, Mid, and East Populations. L_2=5 \mathrm{~m}, \quad \bar{\delta}=1 \mathrm{~mm} 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? Which of the following best describes the expected distribution of proboscis size of the moths at the end of the fiveyear study? C. The original habitat contained many predators, and the species diversified in order to avoid extinction. The original habitat had many available unoccupied ecological niches that were colonized by populations of the original species. Telomeres consist of hundreds or thousands of repeats of the same short DNA sequence, which varies between organisms. The second group is fed the same food without the mutagen. WebDownload free-response questions from past AP Biology exams, along with scoring guidelines, sample responses from exam takers, and scoring distributions. (c) silicon A. Natural selection acted on variation that was present in both populations A and B, and the lack of gene flow eventually led to the formation of two new species. describes how the L. clathratus population would be affected? A group of birds is found in an island chain that have all descended from a single ancestral species. A thermometer requires 1 min to indicate 98% of the response to a step input. A scientist is studying the impact of mutagens on genetic variation in mice. 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. A. C. Organisms in Bacteria, Archaea, and Eukarya each have adenine, thymine, guanine, and cytosine bases forming their DNA. C. The animals in population A accumulated fewer genetic mutations, adapting to their microclimate. The original habitat had many available unoccupied ecological niches that were colonized by populations of the original species. Current temperature changes will correlate with temperature changes during previous extinctions. If the gage reads a pressure differential of 4kPa4\ \mathrm{kPa}4kPa, find the flow rate of ammonia through the pipe, and the average flow velocity. In addition to the ABO blood groups, humans have an MN blood type system in which the M and N alleles are codominant to one another. Graph that starts at 5.0 cm and ends at 9.0 cm. The model is shown in Figure 1. The population was predominantly black throughout the nineteenth century. Start each population with genetically identical bacterial cells from a single culture to make sure that the initial genetic variation in all of the populations was exactly the same. Both the larger population and the isolated population were maintained under identical conditions and allowed to mate randomly for another 20 generations. B. C. The plant species will flower earlier in the spring in response to rising temperatures before the arrival of the pollinators, so seeds will not be produced. Assuming that the population is in HardyWeinberg equilibrium, which of the following is the expected frequency of individuals with the genotype MNMN? Observed modern extinction rates will resemble the rates found early in previous extinctions. WebClick the card to flip . Controlled fires in counties 4 and 5 will lead to an increase in the sparrow population. In an exercise to understand how genetically controlled physical traits could affect speciation, a theoretical population was imagined that contained organisms with three shapes and three levels of pigmentation, as illustrated in Figure 1. C. Humans and mice share a recent common ancestor that had the 5-TTAGGG-35-TTAGGG-3 repeat sequence in its telomeres. Which of the following best predicts why the recombinant bacteria will fail to produce the eukaryotic protein? A. WebAp Bio Unit 7 Progress Check Mcq Answers. WebAP Biology Scoring Guide Unit 7 Progress Check: MCQ Part A 2. After the 20 generations, DNA sequencing was used to determine the genetic composition of each population. There is no difference in iridium levels in sediments that were deposited on Earth 3.6 billion years old, compared to recent sediments. D. The lizards will hybridize with a different lizard species that is adapted to a warmer environment, leading to increased genetic variation in the species. Which of the following represents an alternate hypothesis tested by this experiment with regard to the population sizes of Henslow's sparrows? The M4M4 and M5M5 populations have the lowest genetic diversity of all populations. One group is given food with an added substance that is known to be a mutagen. Both the larger population and the isolated population were maintained under identical conditions and allowed to mate randomly for another 20 generations.
