Did Mars have the elements present in its atmosphere to support life? Which of the following best describes the importance of the number of amino acid differences indicated in Table 1? a. They reflect the different environments where the organisms were captured b. They reflect the number of base pair changes in the DNA The sequencing will provide additional information for answering which of the following questions? a. Is species I the common ancestor of species II and III? c. Are species III and IV the most closely related? Researchers are investigating the evolutionary relationships among organisms found near deep-sea hydrothermal vents and similar organisms found closer to the ocean surface. Which of the following scientific questions is most relevant to the investigation? a. What are the nucleotide sequences of ribosomal RNA genes that are found in the genomes
of the different species? a. What are the nucleotide sequences of ribosomal RNA genes that are found in the genomes of the different species? A group of students summarized information on five great extinction events. The students are sampling a site in search of fossils from the Devonian period. Based on the chart, which of the following would be the most reasonable plan for the students to follow? a. Searching horizontal rock layers in any class or rock and trying yo find those that contain the greatest number of fossils. b. Collecting fossils from rock layers deposited prior to the Permian period that contain some early vertebrate bones Which of the following rows of data listed in table 1 best supports the possibility of a common ancestor for the organisms listed there? a. Vascular Tissue c. Cell wall composed of cellulose Which of the following data could best support the claim that species B arose from a speciation event in Lake I? a. All of the fish species occupy the same niches in their respective
lakes b. DNA analysis shows fever differences between species A and species B in lake I than between species B and the populations in Lake II Interpretation of the data supports which of the following statements? a. Rhesus monkeys are more closely related to rabbits than they are to horses e. Mammals are more closely related to reptiles than fish Which of the following best predicts how phylogenetic relationships might be revised if transposon 1 was not found in chimpanzees? a. Bonbons would be more closely related to humans than to chimpanzees b. Chimpanzees would be more closely related to humans than to bonobos Many scientists claim that the synthesis of the first organic molecules from inorganic precursors was possible because of the highly reducing atmosphere found on primitive Earth. a. The level of atmospheric oxygen on modern Earth is significantly higher than on a primitive Earth c. The synthesis of organic molecules from inorganic molecules is possible under current atmospheric oxygen levels as well as those found on primitive Earth The wing of a bat, the flipper of a whale, and the forelimb of a horse appear very different, yet detailed studies reveal the presence of the same basic bone pattern. These structures are examples of a. analogous structures b. homologous structures By discharging electric sparks into a laboratory chamber atmosphere that consisted of water vapor, hydrogen gas, methane, and ammonia, Stanley Miller obtained data that showed that a number of organic molecules, including many amino acids, could be synthesized. Miller was attempting to model early Earth conditions as understood in the 1950s. The results of Miller's experiments best support which of the following hypotheses? a. The molecules essential to life today did not exist at the time Earth was first formed c. The molecules essential to life today could have formed under early Earth conditions Which of the following proposes the best alternative hypothesis for the claim? b. Climate analysis conducted by sampling pollen preserved in amber shows an increase in grass pollen 29 million years ago, which indicates there was an increase in grasslands that correlates to an increase in butterfly speciation during the same time period. Which of the following best explains the presence of prolactin in various vertebrate species? a. Though all vertebrates produce prolactin, its varied uses indicate it arose as a result of convergent evolution and not as a result of common
ancestry b. Prolactin is a homologous hormone because it has a common origin but different functions in various species Lobe finned fishes were present in the oceans of the world approximately 400 million years ago. The first tetrapods ( vertebrates that had limbs and could move on land) date to about 365 million years ago. One hypothesis states that early tetrapods evolved from lobed-finned fishes. Which of the following is the best plan for testing the hypothesis? a. Determining the number of fins found on the lobe-finned fishes from different geographical locations c. Comparing the arrangements of bones in the fins of lobe-finned fishes and limbs Which of the following observations best supports the hypothesis that a large object collided with Earth in a period of time associated with a mass extinction? a. A species found only in Australia resembles a species found only in North America d. Iridium, which is common in meteorites but rare on Earth, is found in sedimentary rock that contains the last appearance of many species in the fossil record. Group IV of the cladogram most likely includes which of the following species? a. P and S only P and S only Which organism would the researchers most likely predict to be the most distantly related to eukaryotes? a. Organism I a. Organism I Which of the following best supports a claim that TTX resistance arose independently in T. atratus and T. sirtalis? a. The stomach contents in fossils of both species include the remains of food items that contained TTX c. The two species of snakes have different genetic mutations in the SCN4A gene Sets found in the same folderAp bio unit 354 terms butterflylovr529 AP bio final exam FRQs19 terms marthaann27 Big Idea 2 FRQ Questions23 terms Rosey003 Cellular Respiration Multiple-Choice Questions17 terms colleenpalmer4 Other sets by this creatorAnatomy Final Sem 2113 terms katelynnlam Anatomy test 5/17/2232 terms katelynnlam AP Psych Ch. 1416 terms katelynnlam anatomy vocab 1510 terms katelynnlam Other Quizlet setsOrganic Chem Exam One Review17 terms jessica_carlton1 Sociology Exam 2: Chapter 5,6 and 7 Study Guide187 terms SamanthaLawton02 Operations processes63 terms Tijil_Agarwal Lymphocyte Receptors Qz - A&P2 [Jones]74 terms kat13dancerPLUS Related questionsQUESTION What is taphonomy and its importance? 2 answers QUESTION What are 4 types of Speciation? 15 answers QUESTION T\F: The Mesozoic Era precedes (is older than) the Paleozoic Era. 2 answers QUESTION How fast can a whale carcass disappear on the ocean floor? 15 answers Which of the following best predicts how phylogenetic relationships might be revised if transposon 1 was not found in chimpanzees?Which of the following best predicts how phylogenetic relationships might be revised if transposon 1 was not found in chimpanzees?

Which statement is best supported by the theory of evolution?Which statement is best supported by the theory of evolution? Populations that have advantageous characteristics will increase in number.
How does DNA provide evidence that species may be changing over time?DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
