A scientist wishes to provide experimental evidence to support the model shown in Figure 1 by demonstrating the ability to synthesize an RNARNA molecule. Dark color is selected for in mice from the West, Mid, and East populations. 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. 19 Attempt 2: Communities & Ecosys, Teaching and Learning Across the Lifepsan. A group of researchers claim that chance events play an important role in the evolution of populations. A scientist maintains a large population of the fruit fly Drosophila affinis in the laboratory. Telomeres consist of hundreds or thousands of repeats of the same short DNA sequence, which varies between organisms. Humans and mice share a recent common ancestor that had the 5-TTAGGG-3 repeat sequence in its telomeres. D. Grey Box, grey box and grey box. The telomeric repeat sequences for selected organisms are given in Table 1. a) filtering blood of harmful substances. C. Set up a new experiment in which these insects are sprayed with two different insecticides to see if they are more effective than Insecticides #1 and #2. 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. Which of the following best explains the phenotypic pattern in the moths over time? 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. Iridium is an element that is rare on Earth but commonly found in meteorites. D. Spray these insecticides on a different species of insect (whose genotypes are also known) to determine its effectiveness on insects that are not pests.

WebUnit 7 MCQ 4.9 (31 reviews) Flashcards Learn Test Match Which of the following best describes the processes occurring between the mouse populations and their Current temperature changes will correlate with temperature changes during previous extinctions. Over time, populations A and B developed into two distinct species. The model is shown in Figure 1. 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. Numbers above 0.125 indicate a high degree of relatedness. After the 20 generations, DNA sequencing was used to determine the genetic composition of each population. Both the larger population and the isolated population were maintained under identical conditions and allowed to mate randomly for another 20 generations. Because cheetahs, Acinonyx jubatus, experienced a bottleneck event about ten thousand years ago, living cheetahs exhibit very little genetic variation compared to other living species of large cats. D. The animals in population A mate at different times of year, causing their gametes to be incompatible with those from animals in populations B, C, and D. B.

Are the following statements true or false? In the presence of available energy and the absence of a significant quantity of atmospheric O2 simple proteins will form spontaneously from a mixture of amino acids. ayo **** that girl who gave me the wrong answers. Figure 1 shows the phylogeny of the birds. Suppose that a 15m/s15-\mathrm{m} / \mathrm{s}15m/s wind is blowing across the roof of your house. Because the mice are highly inbred, they are essentially identical to one another. A group of birds is found in an island chain that have all descended from a single ancestral species. An experiment is designed to help prevent the further decline and extinction of the Henslow's sparrow in which controlled burns will be set in the each of the ten Midwest counties in order to prevent the regrowth of the forest. Which of the following best explains the mechanism that caused this speciation event in the giant kangaroo rats of population A? A small segment of the original population is exposed to different environmental conditions, and a new subspecies emerges through natural selection. The degrees of relatedness in several native populations of prairie chickens in Marion and Jasper Counties in Illinois were determined. Scientists interested in the relationship among vision, foraging for food, and fitness studied three isolated populations of a small species of primate whose WebAP Biology Scoring Guide Unit 7 Progress Check: MCQ Part A 2. The current global warming trend is placing new selective pressures on the species involved in these relationships. C. During the nineteenth century, increased ship commerce between Great Britain and Ireland facilitated the gene flow of the black variety, spreading it throughout the moth's normal range. The increased air pollution of the nineteenth century due to the use of coal led to a darkening of surfaces from soot. Some researchers claim that the decrease in plant species richness of this woodlot is unrelated to human activities over the last forty years. There will be no difference in the populations observed in the controlled fire sites and the rest of counties 5 and 6. A. Introns must be removed from eukaryotic DNA before the gene is inserted into the plasmid. A. Which of the following student claims is best supported by the data provided?

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? D. Controlled fires in counties 4 and 5 will lead to an increase in the sparrow population. The increased air pollution of the nineteenth century due to the use of coal led to a darkening of surfaces from soot. Which of the following is an alternative hypothesis that can be tested to support the RNARNA World Hypothesis? Because the mice are highly inbred, they are essentially identical to one another.

D. In response to different environments, populations A and B experienced different mutation rates, leading to the emergence of two different gene pools and, over time, new species A and B. Which of the specimens indicated in the table is the oldest? D. The black variety was a nineteenth century mutation, dominant to the peppered variety. B. Geographic isolation will create separate gene pools, leading to speciation over time. C. Most of the species found in the first static period will be absent in the second static period. 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. The darker backgrounds conferred a selective advantage to the black variety, as described by natural selection. Cattle and sheep are separated by only one node, and they are separated from the other organisms by more than one node. Neither group of mice will show any change in the ability to digest the food because thousands of years are required to develop such a change. Take a look at the Intro to Unit 7. In an experiment, the scientist creates two groups of twenty highly inbred mice. Select the best alternate hypothesis to support this claim. Which of the following best describes the processes occurring between the mouse populations and their environments? Cells with flagella were better able to find food and escape predators. C. Cells with ribosomes were better able to produce proteins needed for a variety of metabolic functions. 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. B. c) storing bile that is released into the bloodstream. An experiment is designed to help prevent the further decline and extinction of the Henslow's sparrow in which controlled burns will be set in the each of the ten Midwest counties in order to prevent the regrowth of the forest. A researcher uses the protocol shown in Figure 1 to isolate a eukaryotic gene for the purpose of genetically engineering bacteria to synthesize the corresponding protein. A scientist is studying the impact of mutagens on genetic variation in mice. Populations with little genetic diversity are less likely to contain individuals that can withstand different selective pressures.
