By the end of the twentieth century, the peppered version of the moth was again more common than the black version. The warmer temperatures will lead to a drier environment, so the plants will no longer produce enough nectar to attract the pollinators. The flow rate of ammonia at 10C(=624.6kg/m310^{\circ} \mathrm{C}\left(\rho=624.6 \mathrm{~kg} / \mathrm{m}^3\right.10C(=624.6kg/m3 and =1.697104kg/ms\mu=1.697 \times 10^{-4} \mathrm{~kg} / \mathrm{m} \cdot \mathrm{s}=1.697104kg/ms ) through a 222-cm\mathrm{cm}cm-diameter pipe is to be measured with a 1.51.51.5-cm\mathrm{cm}cm-diameter flow nozzle equipped with a differential pressure gage. A dark coat color provides camouflage to mice on the lava flow rocks; therefore, mice with dark coats have a lower predation rate in that habitat. Statistics and Probability questions and answers; College Board AP Classroom Unit 7 D. Mice utilized the 5-TTAGGG-35-TTAGGG-3 telomeric repeat sequence first, but the sequence independently evolved in humans as well. Formation of crude proteins occurs by chance and occurs regardless of atmospheric O2O2 levels or available free energy. Observed modern extinction rates will resemble the rates found early in previous extinctions. Table 1 shows the collected data. Which of the following principles best justifies a claim that cheetahs, compared to other large cats, have a relatively low resilience to environmental perturbations? If the environment for the plant species becomes too warm, the pollinators will no longer migrate to that area in the spring, continuing on to a more northern environment instead. D. The M4 and M5 populations have the lowest genetic diversity of all populations. A shift to less polluting fuel in the twentieth led to cleaner air and a lightening of the moth's normal habitat. Which of the following predicts the expected outcome of the experiment? describes how the L. clathratus population would be affected? Which of the following best explains the divergence in morphology in the birds? WebIt is Monday morning, May 13, and you will be taking the AP Biology Exam. The island was surveyed again in 2015, and scientists determined that the giant kangaroo rats originally in population A are now to be considered as a new species. AP Bio 7.14 Multiple Choice Questions | Fiveable The researchers built an enclosure to prevent migration into and out of the O'Neill rock pocket mouse population for a period of two years. The scientists identified a period of stability or stasis, followed by rapid change, and then stasis again with regard to shell shape. A. Scientists studying the fossils observed patterns of changing shell shape in the mollusks. If sediment layers that are 3.6 billion years old are tested, they will contain relatively high iridium levels, because that is when many meteorites crashed into the Earth. D. Large population size. Which of the following best explains the mechanism that caused this speciation event in the giant kangaroo rats of population A? B. Bacterial ribosomes cannot recognize eukaryotic mRNA and will not translate the codon sequence. The original habitat contained mutagens, leading to the rise of new species as a result of accumulated mutations. Controlled fires in counties 4 and 5 will lead to an increase in the sparrow population. After 20 generations of allowing this population of about 1000 flies to mate randomly, 10 females and 10 males were isolated from the rest of the population. C. If a sediment layer that is 3.6 billion years old is tested, it will contain organic material. Catalase is a protein enzyme that catalyzes the breakdown of hydrogen peroxide (H2O2) into water and oxygen gas in the cells of many living organisms. By the end of the twentieth century, the peppered version of the moth was again more common than the black version. Even though there are numerous mountains in the region, the climate on the mountains is too cold for the lizards to survive. These building blocks combined to form polymers, such as crude proteins. WebLearn about unit 7 of AP Biology as we cover topics such as artificial selection, population genetics, hardy-weinberg equilibrium, evidence of evolution, common ancestry, continuing The MC1RD allele is not responsible for dark coat color in the Carrizozo population, so the dark coat color is likely a result of convergent evolution. WebAp Bio Unit 7 Progress Check Mcq Answers. During the last few decades, tall buildings have been built around the woodlot, and species 3, 4, and 5 are shadeintolerant plants. To prevent the loss of genes as chromosome ends wear down during DNA replication, the tips of eukaryotic chromosomes have specialized DNA "caps" called telomeres. A captive population of cheetahs kept in a confined area will have a greater risk of contracting and passing on a virus. A. The frequency of homozygous recessive individuals will increase because light-colored fur absorbs less heat. Which of the following is closest to the frequency of the MC1RD allele in the Tule Mountain population? Telomeres consist of hundreds or thousands of repeats of the same short DNA sequence, which varies between organisms. A scientist believes that the first organic molecules may have come to Earth on meteorites 3.6 billion years ago. Take a look at the Intro to Unit 7. Immigration of individuals from Metro Manila into the two populations. A_1=25 \mathrm{~mm}^2, \quad A_2=50 \mathrm{~mm}^2, \quad L_1=3 \mathrm{~m}, \\ C. The animals in population A accumulated fewer genetic mutations, adapting to their microclimate. Which of the following best explains the mechanism that caused this speciation event in the giant kangaroo rats of population A? By 1940, most genetic variation for speed had been lost from the gene pool. The degree of relatedness is inversely proportional to genetic diversity; that is, populations with a high degree of relatedness have less genetic diversity. Click the card to (c) silicon provided unique evolutionary advantages to the last eukaryotic common ancestor? Increasing the number of trials and the number of mice in each treatment group. A. Consider the circuit in the given figure with resistors R1=2500,R2=4500R_1=2500 \Omega, R_2=4500 \OmegaR1=2500,R2=4500, and R3=1200R_3=1200 \OmegaR3=1200, and batteries with emfs E1=6.5V\mathcal{E}_1=6.5 \mathrm{~V}E1=6.5V and E2=1.3V\mathcal{E}_2=1.3 \mathrm{~V}E2=1.3V. What is the magnitude of the current in the circuit? Based on the information provided in the figure, which of the following best describes how membrane-bound organelles provided unique evolutionary advantages to the last eukaryotic common ancestor? There are two species of elephant seals: northern elephant seals, Mirounga angustirostris, found off the western coast of North America from Baja California to the Gulf of Alaska, and southern elephant seals, M. leonina, found in the southern oceans. The darker backgrounds conferred a selective advantage to the black variety, as described by natural selection. C. Most of the species found in the first static period will be absent in the second static period. Graph that starts at 5.0 cm and ends at 9.0 cm. C. The number of species present on Earth will equal the number of species on Earth before the last extinction. B Cattle are equally related to pigs and sheep, because the phylogeny places cattle between pigs and sheep. In an experiment, the scientist creates two groups of twenty highly inbred mice. Students used an online database, which used the structure of catalase from different species, to generate the phylogenetic tree shown in Figure 1. n 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. A. AP Biology Unit 7 Evolution MCQ Questions 14.pdf - AP Organisms in Bacteria, Archaea, and Eukarya each have adenine, thymine, guanine, and cytosine bases forming their DNA. A . D. Cattle and sheep are separated by only one node, and they are separated from the other organisms by more than one node.
