Biology for a Changing World 2e,Chapter 1 Test Bank1.A hypothesis is a statement thatA.can bechanged throughout the experiment.B.can beavidly accepted by scientists.C.can betested and proven true.D.can betested and proven false.E.precedesa theory.Answer: DDQ: How is the scientific method used to test hypotheses?Type: Know ItDifficulty: EasyImportant Words/Concepts: understanding scientific studies2.Where are the most reliable scientific results published?A.inthe daily newsB.in science magazinesC.inscience journalsD.onscientific websitesE.in peer-reviewed scientific journalsAnswer: EDQ: How is the scientific method used to test hypotheses?Type: Know ItDifficulty: EasyImportantWords/Concepts: understanding scientific studies3.Imagine that you read a study of the effects of exercise on the prevalence of heart disease inwomen ages 35 to 65. Although you believe the experiment was carried out in anappropriate manner, you still do not believe the results. You decide to conduct your ownstudy to see for yourself. To determine if the results of the first study are valid, should youdo everything the same way as the first study or wouldit be better ifyou changedseveral ofthe variables, such as studying men, or looking at different age groups? Explain your choice,and explain the consequences of the other choice.Answer:To be most comparable, you would conduct your new study in the exact samemanner as the previous study. If you were to change any of the variables, then the resultsmight change as well; thus, you would not be able to compare your new results to the firststudy.DQ: How is the scientific method used to test hypotheses?Type: Use ItDifficulty: EasyImportant Words/Concepts: contradictory results, experimental differences, process of science4.The scientific process from beginning to end can be outlined as:A.hypothesize, test, analyze, and conclude.
