Organism C is the outgroup, B and E are the most closely related I would definitely recommend Study.com to my colleagues. C. Neither. This information shows that humans have a more common ancestor with chimpanzees and bonobos and are therefore a monophyletic grouping. These will be further discussed in the rest of this lesson.

D. predation, The process in the water cycle that moves the most water during a given time is: E. A gamete from this species has 4 chromosomes, Huntington's disease has been shown to be more severe with an earlier onset in the children dwhen the allele for Huntington's comes from the father instead of the mother. E. Evolution acts at the individual level rather than the population level, Xeroderm pigmentosum is a recessive mutation in a nucleotide sequence repair enzyme. C. 300 Species diversity decreases Explain what is meant by this term and provide 3 different examples of how this is true. Does this change you answer in A) above? On a cladogram, you will commonly see hash marks that indicate a synapomorphy or shared common trait. 2. According to the cladogram of primates shown, which key cultural which of the following lists the taxa form broadest to most specific>, domain, kingdom, phylum, class, order, family, genus, species. A. have seeds that are easily dispersed by wind or animals Weegy: In physics, power is the rate of doing work. A. A. true The numbers 1 through 5 represent species that exist today. D. Mechanical C. the resulting uniform habitat supports stability, which in turn supports diversity To unlock this lesson you must be a Study.com Member. A. mutualism C. reptiles D. matter is being continually converted into heat and back into matter Today, grouping is created by comparing the genetic information of organisms. A phylogenetic tree may be built using morphological (body shape), biochemical, behavioral, or molecular features of species or other groups. grasses Yinka also lacks the trait, but her mother has hemophilia and her father is unaffected. B) no, children of both matings have the same chance of expressing hemophilia because both Vanessa and Yinka are carriers, Which sequence represents the most likely chronological order of events in the development of geographic speciation, from earliest to latest? The presence of mountain ranges tends to produce extremes in precipitation Amnitoes 5. the is one reason the two organisms are placed in different and more. Question what kind of fragment is "near the computer"? B. primary productivity The shaded taxa correspond to groups that have evolved jaw like structures. BSCI 160 Final Flashcards | Quizlet Which synapomorphy unites the pigeons and the lizards? A. incomplete dominance The numbers 1 through 5 represent species that exist today. D. none of them, A triploid cell contains three sets of chromosomes. B. fragmentation 50% Suppose a mutation occurred in the sperm that fertilized an egg to produce you, but that mutation did not occur in the sperm that produced your brother. the science of classifying living things is called, which of the following scientists developed the system of classifying organisms by assigning them a genus and specific name. Eventually, the number of bird species inhabiting the islands will be the same, although the amount of time it takes for this to be established on each island will differ A. All rights reserved. _________ is the branch of biology that classifies living things in a hierarchical system. D. the relatively small degree of homology shared by the X and Y chromosomes All eukaryotes and some prokaryotes As seen in the cladograms above, the figure shows grouping examples, including a monophyletic group. Since all these organisms share a common ancestor, they also share a synapomorphy, which is that earthworms, birds, and snakes all reproduce sexually. D. environmental changes can make a previously neutral mutation advantageous A. larger; closer to E. disperse many seeds in close proximity to the parent tree, A. have seeds that are easily dispersed by wind or animals, Generally speaking, deserts are located in places where air masses are usually: Each line is called a branch. This trait is an example of what kind of evolution? Provide two evidences to support the theory of endosymbiosis, Endosymbiosis: origin of eukaryotes as one species being engulfed by another B. both photosynthesis and respiration cycle carbon through inorganic pools A Taxa are simply groups of organisms. Find the allele frequencies and expected genotype frequencies. A cladogram may be defined as a type of diagram that shows speculative relationships between groups of organisms of the same species or different ones.. Cladograms are visual representations of monophyletic groups and indicate the shared ancestors and shared characteristics or synapomorphies of a monophyletic group. Taxa can be general groups of organisms, such as vertebrates, or they can be as specific as a species, like an African Elephant. New York City would receive more sunlight in june If a female of this species has one chromosome 12 with a blue gene and another chromosome 12 with an orange gene, and has both number 19 chromosomes with short genes, she will produce which of the following egg types? A mutation in a gray fox population reduces both fecundity and survivorship to a given age A. common names are too ambiguous.

B. false, The sexy son hypothesis states that males that can produce/maintain elaborate displays must be resistant to parasites B. that are nearby or within the same tissue. A. true According to the characteristics described above, the koala belongs to the letter F in the cladogram that reveals the modification . To survive, pathogens must do two things: Explain why harmful (lethal) alleles in humans persist in a population, unable to be eliminated like the breast cancer mutation, Heterozygote advantage: balance survival and reproduction heterozygotes have the best balace and therefore highest fitness. 1 pt. Question what kind of fragment is "near the computer"? C. Bears eat blueberries; then they defecate the blueberry seeds throughout the forest, and the seeds germinate Island 1 could be the same size as Island 2 and closer to the mainland than Island 2 refer to the cladogram shown above weegy.
