AP Biology Practice Test 4: Origin of Living Systems pdf download. Sickle Cell Disease is caused by having two alleles for Hemoglobin S. The Hemoglobin S allele results red blood cells that have a sickle shape. e.) A and C, The allele that causes phenylketonuria (PKU) is harmful, except when an infant's diet lacks the amino acid, phenylalanine. Gene-for-gene recognition is the mechanism that allows the plant to recognize pathogens based on the recognition of pathogen-derived molecules. By looking at the genes of the polar bears, they found that the polar bears have recently begun to move in a northward direction, from Southern Canada and Eastern Polar Basin into the Canadian Archipelago. In that population, ten of the birds are brown. To observe natural selections effects on a population, which of these must be true? When researchers put males and females from different sides of the isthmus together, they snapped at each other aggressively instead of mating. Why is surface water both a creator and a destroyer of sediments and sedimentary rocks? By providing links to other sites, www.brainbeau.com does not guarantee, approve, or endorse the information or products available on these sites. -Evolution occurs in a population as advantageous traits accumulate or as disadvantageous ones disappear from a population, How the Giraffe Got Its Long Neck (According to Theory of Natural Selection), -Some giraffes had long necks and some had short necks 5 0 obj Ana_Sanchez578. Part of the population becomes geographically isolated from the main population, separating the population into two isolated groups. Archaeans are unicellular prokaryotes. The team of researchers hypothesized that the Canadian Archipelago will be a future refuge for polar bears if climate change continues to trend toward a warmer climate. Descent with modification; the idea that living species are descendants of ancestral species that were different from the present-day ones; also defined more narrowly as the change in the genetic composition of a population from generation to generation. Mechanisms of Evolution. -Ex. vestigial Sympatric speciation brought about by polyploidy, Hybridization caused by geographic isolation, Allopatric speciation caused by geographic isolation, Coevolution brought about by habitat isolation. Big Idea 2: Energetics. 10 -Ex. c.) large population size Israel has the highest average gene diversity, and is likely to be the center of origin. The function $f(x, t)=A \sin 2 \pi[(x / \lambda)-v t]$ represents a sine wave of frequency $v$ and wavelength $\lambda.$ The wave propagates along the x axis with velocity = wavelength $\times$ frequency $=\lambda \v. --- Your performance has been rated as %%RATING%%, Next Practice Test: d.) 1, 3, and 4 The correct answer is (B). If you leave this page, your progress will be lost. The mesoderm partly fills the space between the endo- and ectoderms. Question 3. Polyploidy is a condition in which a cell is formed that has an extra set(s) of chromosomes. Males of one species sing only during rainy conditions; males of another species sing only when it is not raining. A severe drop in population size can cause a bottleneck effect. If two species evolve different mating rituals, it may permanently isolate them from one another and complete the process of speciation. The solution readily passes through cell membranes. c.) it is synonymous with the process of gene flow -The fittest male gets to pass on his genes to the next generation, -In preindustrial England, most peppered moths were light-colored because they were camouflaged by the bucolic countryside; therefore, they had the advantage over dark moths AP Biology Practices . When these gametes fused with other gametes the result was offspring with additional sets of chromosomes. The correct answer is (A). \end{array}\right]. e.) the allele reduces fitness, The following important concepts of population genetics are due to random events or chance *except* -Example of sympatric speciation Sympatric speciation occurs in populations that live in the same geographic regions.

In this case, certain alleles were overrepresented in the population of survivors, and other alleles were underrepresented. The organisms with the best suited characteristics for their environment will live to reproduce, and pass those characteristic on to their offspring. Although they have the sickle cell trait, they do not have sickle cell disease. However, one percent of the deer population exhibit a recessive genetic trait found in about one percent of all white-tailed deer called leucism. 37 terms. d.) geographic isolation from one another The correct answer is (C). e.) reproductive isolation from one another, The Hawaiian Islands are a great showcase of evolution because of intense Quizlet for Molecular Genetics AP Biology. 2323 times. The process of evolution explains the unity of life as well as its diversity. 0.001 e.) camouflage coloration in animals, Successfully breeding two individual organisms at a zoo and obtaining fertile offspring for several generations is no guarantee that the same could occur in nature (i.e., in the wild). c.) Population 3 b.) Allow students to reflect on new knowledge. %PDF-1.5 % a.) Phylogenetic trees show relationships between groups of organisms. Multiple Choice. This tree shows that crocodilians are more closely related to lizards and snakes, than to ornithischian dinosaurs, which are not adjacent to the crocodilians on the tree. A group of mice becomes separated Easy Peasy All in One High School. AP Biology Evolution DRAFT. 25% of the time is spent in the lab study environment where students conduct hands-on investigations and apply scientific practices. The correct answer is (D).

Chordata is the phylum to which vertebrates belong along with the Craniata (such as hagfish), Unichordata (such as tunicates), Cephalochordata (such as lancelets), and, possibly, echinoderms. In this case, certain alleles were overrepresented in the population of survivors, and other alleles were underrepresented. d.) A and B New World vultures (Cathartidae family) and Old World (Accipitridae family) vultures look very similar, both have featherless necks and hears, and feed on carrion. c.) 2 and 3 Because of their selective advantage, brown anoles that remain on the ground will likely produce more offspring in each generation than brown anoles that move higher in trees. AP Biology: Evolution Overview Chapter Exam. In certain chemical forms, oxygen attacks chemical bonds and can inhibit enzymes and damage cells. Polygenetic, as in polygenetic inheritance, refers to the effect of two or more genes on a single phenotypic character. This presents a clear example of genetic drift due to a small founding population. change in allele frequencies as a result of the migration of a small subgroup of a population, A change in allele frequency following a dramatic reduction in the size of a population.
