-1-BIOS 100 - Fall, 2010 Name:Exam I, 17 Sept, 2010Michael Muller, Instructor TA:This exam consists of 40 questions over 8 pages (the last page also has a periodic table). Each questionis worth 4 points apiece (so, yes, you can earn 160 points) Please check to see that all the pages arepresent before you begin. There are some useful diagrams on the last page - check them out before youstart taking the exam. Use a #2 pencil and bubble in all answers. Your score will be posted on the UICBlackboard site as soon as they are in. Choose the BEST answer for each question. Good Luck! 1. Which of the following statement (A-D) about the process of science is FALSE? If statementsA-D are true, then choose EA. A hypothesis which is not falsifiable is not a valid scientific hypothesisB. Science is an evolving field - the state of our knowledge is constantly changingC. You can never prove a hypothesis to be true, you can only continually support it withobservational and experimental dataD. Scientific theories and models are compilations of linked hypotheses used to explainlarger scale phenomena and they can be used to predict outcomes for situationsthat have not been observed or data collected.E. All of the above statements about the process of science are TRUE2. A non-science major took this BIOS 100 course three years ago to fulfil their GenEdrequirement and have since not taken another science course. They gave a grouppresentation using Power Point on the history and treatment of people with HIV. I gavethis student a copy of the final exam and interspersed questions about the treatment ofHIV. They did acceptable on the general biology questions, but did exceptionally well onthe HIV questions. What is the best scientific explanation for these results?A. HIV is a topically relevant subject and they have been exposed to this information inthe mediaB. It is possible that they have a relative or close friend who has HIV and retaining thisinformation has comforted them C. Teaching others about a subject is the most effective way to promote long-termlearning of the topicD. The use of AV material and Power Point have been demonstrated to improve learningand retention of materialE. None of the above3. Which of the reasons given below was NOT given by the judge in the Kitzmiller v Dovercourt case for why Intelligent Design (ID) is not science?A. All of ID’s claims have not been scientifically demonstratedB. ID’s negative attacks on evolution have been refuted by the scientific communityC. The argument of irreducible complexity, central to ID, employs the same flawed andillogical contrived dualism that doomed creation scienceD. ID violated the centuries-old ground rules of science by invoking and permittingsupernatural causation for natural phenomenaE. All of the above reasons were cited by the judge in the Kitzmiller v Dover case-2-4. Which of the following statements could not be supported or rejected by a scientificexperiment? A. The first living cells came from outer spaceB. Production of melanin, a pigment in the skin, is affected by vitamin C intakeC. Wearing seatbelts helps reduce major injury and/or death in auto accidents D. College students prefer low-cost textbooks to high-cost textbooksE. All of the above statements could be supported or rejected by scientific experiments.5. What was one of the main points of the Zheng et al. article Application of Bloom’s TaxonomyDebunks the “MCAT Myth”?A. The common belief that the MCAT is a good indicator of success in medical school isnot supported by performance data and job placementB. The common belief that the MCAT is mostly a collection of factual recallquestions is not supported by the study performed by Zheng et al.C. The common belief that exams given during the first year of medical school consistprimarily of lower-order knowledge questions was not supportedD. Introductory level biology courses (such as BIOS 100) need to have more of a basis infactual information as these are the tools necessary for success on the MCAT andmedical schoolE. None of the above6. Which of the following levels of learning is considered by Bloom’s Taxonomy to be thelowest level of learning?A. Analyzing B. Evaluating C. UnderstandingD. Remembering E. Creating7. What level of learning was required by you to answer the above question on Bloom’sTaxonomy?A. Analyzing B. Evaluating C. UnderstandingD. Remembering E. Creating8. Experiments performed in the medical field testing the effectiveness of drugs frequentlyemploy what is called a double blind experimental design. What is the function of adouble blind experimental design?A. It controls for the placebo effectB. It removes potential bias from the patients’ description of the effectiveness of the drugC. It removes potential bias from the doctors’ and nurses’ data collection since theydo not know which patients have received the active drug D. It removes potential bias from the drug company since they have a great financialstake in the resultsE. None of the above9. Based on information presented in the periodic table, which of the following chemicals is themost stable (i.e. follows the simple covalent bonding rules)?24232A. SH B. H Cl C. CO D. H NC E. CN-3-10. Which of the following molecules would you expect to have the strongest dipole?43 32A. CH B. NH C. H O D. CH OH E. None of the above11. You developed a drug to reduce the negative effects of seasonal allergies on patients. Yougathered up a group of people who suffer from the same seasonal allergies and createdthree groups. The first group you gave nothing. The second group you gave a sugar pillbut told them it was a drug and the third group you gave your drug. You measuredeffectiveness of the drug by antibody counts in their blood - the lower the antibody count,the more effective the treatment is in reducing allergies. You obtained the followingresults illustrated by the graph below. What conclusions could you draw from your data?A. There is no effect from either the drug orthe placebo in treating these seasonalallergiesB. The drug is no more effective than aplacebo in treating seasonal allergies.C. The drug is significantly better than aplacebo in treating seasonal allergiesD. You cannot draw any conclusions based onyour data 12. Which of the following molecules would have the least solubility in water?6126 326A. HCl B. NaCl C. C H O D. C H E. CH OH13. You
