Figure 3 shows genetic information from woolly mammoths, African elephants, and Asian elephants. Which elephant is more closely related to the woolly mammoth?, African elephant, Asian elephant, They are equally related to the mammoth., Neither is related to the mammoth., Amino acids such as the ones shown in Figure 3 provide us with what type of evidence for evolution?, They show similarities in anatomy between two or more organisms., They show similarities and differences in the genetic information between two or more organisms., They are remains of organisms that give us information on the geographic location in which they existed., They compare the habitats of extinct organisms to organisms that exist today., A highlighted section of Figure 3 is shown above. What is the best explanation for the information contained in the blue box?, There must have been a mutation that changed the DNA before the amino acid was made., More than one DNA sequence can code for the same amino acid., The amino acid is not determined by the DNA., There is no explanation- it must be a mistake., Figure 3 shows DNA sequences and corresponding amino acids of the woolly mammoth, the African elephant, and the Asian elephant. Which of the following is a valid conclusion based on the figure?, The Asian and African elephants do not share a common ancestor based on the many differences in their DNA sequence., The woolly mammoth is most closely related to the African elephant because they have the most similar amino acid sequence., The Asian and African elephants are the most closely related because they have the most similar amino acid sequence., The Asian elephant likely shares a more recent common ancestor with the woolly mammoth than with the African elephant., Figures 1 and 2 provide evidence that woolly mammoths and elephants are related. All of the following pieces of evidence support this claim except...?, Climate records from when woolly mammoths were alive, Bones of woolly mammoth and elephant that have similar structure and placement, Additional DNA samples from both woolly mammoths and elephants, Photos of the embryological development of mammoths and elephants, A change in which of the following will have the most widespread impacts on an organism and potentially its offspring?, DNA, RNA, Protein, Amino Acid, Using Figures 1 and 2, we can conclude that the mutation that caused PKU likely…, Didn’t change the RNA in the body, Affected many different chromosomes, Caused a necessary protein to be missing or non-functional, Originated in the genes of a biological male, Suppose a father has PKU (rr) while a mother has no alleles for the PKU trait (RR). How would this affect the phenotypes of their offspring?, All offspring will have the PKU trait, All offspring will be carriers for the PKU trait, It is impossible to predict the offspring’s phenotypes, None of the offspring will have the PKU trait, Which of the following questions is answered by the statement The mother’s genotype needs to be RR and the father’s genotype needs to be RR., What genotypes must a child’s parents have for them to have a 0% probability of inheriting the PKU allele?, What are the likely genotypes of the parents of a child who has PKU disease?, What are the possible genotypes of the parents of a child who is a carrier of the PKU allele?, What are the genotypes of the parents of a child who has no mutations whatsoever in their DNA?, Which question below is scientifically testable, and can be answered using ONLY the models and data provided?, Is the chance of inheriting the PKU trait the same for people who live outside of the Karachay-Cherkess Republic?, Is PKU a heritable disease that can be passed down from parents to their offspring?, Do PKU carriers have any health issues related to the presence of one copy of the mutated allele?, At what age do people typically learn that they have PKU?, To survive, animals need to be able to control their blood sugar levels. They can do this because, Cells and organs work together to produce specific proteins that do this job for the body, Sugars break down very fast in the bloodstream, so they will never be high or low for too long, The brain tells the body how fast it needs to move to burn off extra sugars, DNA can help the cells absorb and store excess sugar until it is needed to make energy, Use your knowledge from class and refer to Figure 2. Which of these is true about the structure of insulin?, The tertiary structure or 3-dimensional shape of the protein is important for it to function, and is determined by primary structure, which is a sequence of amino acids., The primary structure, or amino acid sequence of the protein is determined by the tertiary, 3-dimensional shape of DNA., The tertiary structure or 3-dimensional shape of the protein is not related to its function but IS important for providing instructions to the cell, None of these can be inferred about the structure of insulin, Insulin is just one of many proteins produced by the body. If someone were to ask you to explain how our bodies are able to make so many different proteins to perform so many different functions, how could you best answer?, All of the proteins enter our bodies fully formed in the food that we eat. This is why it is important to have a diet that is well-balanced and high in protein, All of the information to make proteins to perform functions in the body is encoded in genes, which are regions of the genetic material DNA, All of the information to make proteins comes from our nervous system. When a certain job must be done in the body, nerve cells release this information, All of the proteins our body could ever need are present in the body in small amounts when we are born, and our cells replicate these proteins when needed., Some people are born with a disorder called Type 1 Diabetes, which prevents them from properly regulating their blood sugar. Which explanation for the cause of Type 1 Diabetes is MOST likely based on your understanding of the relationship between genes, proteins, and body functions?, Cells and tissues in the body rely on proteins to carry out certain functions, and the information for these proteins comes from genes, which are made of DNA. A change in the DNA sequence of the insulin gene affects whether or how the cell makes a protein, which prevents organs from properly regulating blood sugar., Proteins in the body rely on special tissues being turned on or off to do their job in the body. At birth, genes tell cells in the tissues of the digestive system to stop making insulin, which prevents the body from properly regulating blood sugar., Certain genes are only found in specialized cells of the body. At a certain age, those cells die, and those genes are lost from the body. This causes the body to be unable to make insulin, causing organs to be unable to regulate blood sugar., People whose mothers did not eat sugar while they were developing caused genes in the infant's body to be unable to recognize insulin. The organs and tissues of the body will store too much sugar resulting in poor regulation., Which of the following factors will MOST increase the rate at which a bacterial population develops antibiotic resistance?, Exposure to antibiotics (medications), Environmental temperature, The amount of DNA their parent bacteria has, The bacteria’s size and shape, Which of the following can result in the presence of mutations in the DNA of an organism?, Errors in DNA coding and replication during mitosis, Environmental factors such as toxins and infections, All of these answer choices can lead to mutations, Inheritance from a parent organism, Refer to Figure 2. Which of the following information can be interpreted based on the data shown in the graph?, The tolerant and persistent bacteria had an equal number of survivors after 6 hours of being exposed to the antibiotic., The persistent bacteria completely died off after 10 hours of being exposed to the antibiotic., The persistent bacteria had better survival rates than the tolerant bacteria group., The susceptible bacteria completely died off after 5 hours of being exposed to the antibiotic., Based on the results shown in Figure 2, which of the following statements is TRUE?, The tolerant bacteria group had the highest fraction of survivors after 10 hours of exposure to antibiotics., The persistent bacteria group had the highest fraction of survivors after 10 hours of exposure to antibiotics., The susceptible bacteria group had the highest fraction of survivors after 10 hours of exposure to antibiotics., All three bacteria groups had the same fraction of survivors after 10 hours of exposure to antibiotics., Which statement about natural selection is false?, Traits that help organisms survive decrease in frequency in populations, Traits that are advantageous for survival and reproduction increase in frequency in populations, There must be variation in traits of a population for evolution by natural selection to occur, Natural selection of populations may be driven by random mutation, changes in climate, or human impacts., Based on the patterns you see in the figures, what do you think will happen if we keep treating mosquitoes with insecticides?, Mosquito populations will eventually stop being immune to the insecticides and will all die., Mosquito populations will become more resistant as survivors pass on their traits., The number of mosquitoes will increase because they will continue to reproduce., The number of mosquitoes will decrease because they are killed by insecticides., Refer to Figure 1. Which statement is true?, There is a higher probability that a mosquito has some level of resistance when only one insecticide is used., There is a higher probability that a mosquito has some level of resistance when more than one insecticide is used., The probability of mosquitoes having some level of resistance to insecticides does not change based on exposure to the chemicals., None of the above, Refer to the image above. How does insecticide exposure affect the distribution of traits in mosquito populations?, As mosquitoes are exposed to insecticides the resistant mosquitoes are selected for, causing a lower proportion of the population to be highly resistant., As mosquitoes are exposed to insecticides the resistant mosquitoes are selected for, causing a higher proportion of the population to be highly resistant., As mosquitoes are exposed to insecticides the non-resistant mosquitoes are selected for, causing a higher proportion of the population to be highly resistant., As mosquitoes are exposed to insecticides the non-resistant mosquitoes are selected for, causing a higher proportion of the population to be less resistant., What cellular process increases genetic variation in populations?, Mitosis, because offspring inherit identical chromosomes from their parents., Meiosis, because chromosome segments cross over., Mitosis, because mutations frequently occur., Meiosis, because each offspring inherits a different number of genes, Which of the following statements about meiosis is incorrect?, Errors can occur during various stages of meiosis resulting in mutations, Meiosis results in four genetically identical cells, Crossing over is a part of meiosis where chromosomes exchange parts, increasing genetic variation., Meiosis results in the formation of sex cells, After observing the sunflowers in Figure 2, your classmates are asked to explain why offspring don’t always have the same traits as their parents. Whose claim is correct?, Lynia, Both Lynia and Stevie are correct., Both Stevie and Clayshawn are correct., Stevie, Clayshawn, The process of cells dividing to form genetically identical daughter cells is called…, Mitosis., Meiosis., Sexual reproduction., Differentiation., Mitosis is an essential function in multicellular organisms because…, It allows the organism to grow., It allows the organism to repair wounds., It passes on all of the vital genetic information to new cells in the body., All choices are correct., How did the creator of Figure 2 represent differentiation?, They showed 2 daughter cells forming from each round of cell division., They showed 2 nuclei in each new cell., They showed how the DNA is changed from parent to daughter cell., They showed different colored substances forming in new daughter cells., In order to fully understand how a salamander regenerates a leg, a complete model would need to show all of the following except:, Mitosis resulting in the creation of 2 daughter cells identical to the parent cell and each other., The differences in the DNA of the differentiated cells as a result of random mutations that happen during the process of mitosis., How the processes of mitosis and differentiation affect the organism at different scales, such as at the molecular (DNA) level, cellular level, and tissue level., Differentiation resulting from gene expression, controlling proteins made by individual cells, and thus the cells' functions..
