HW 02: Animal Form & Function 5/13/15 4:53 PM branched unstriated unbranched and cylindrical spindle shaped striated Correct Cardiac muscle fibers are branched. Part C _____ muscle is attached to bones. ANSWER: Smooth Involuntary Cardiac Branched Skeletal Correct Skeletal muscle is attached to bones. Interpreting Data: Variation in Percentage of Muscle Fiber Types Use the graph to answer these questions. Part A https://session.masteringbiology.com/myct/assignmentPrintView?displayMode=studentView&assignmentID=3451230 Page 268 of 300 HW 02: Animal Form & Function 5/13/15 4:53 PM What do the orange bars on the graph represent? ANSWER: the number of slow muscle fibers in individuals with different athletic abilities the percentage of people who fall into each category of athletic ability the athletic ability of an individual the percentage of slow muscle fibers in individuals with different athletic abilities Correct Part B According to the graph, which type of muscle fiber predominates in endurance athletes (marathon runners and extreme endurance athletes)? ANSWER: slow intermediate fast a combination of intermediate and fast muscle fibers Correct Part C The percentage of intermediate muscle fibers plus fast muscle fibers in world-class sprinters is approximately the same as the percentage of slow muscle fibers in ____________. ANSWER: an average active person an extreme endurance athlete a world-class marathon runner a middle-distance runner Correct Part D When an inactive person becomes active, the percentage of slow muscle fibers ______, and the percentage of fast muscle fibers _______. ANSWER: decreases; increases increases; decreases decreases; decreases increases; increases Correct https://session.masteringbiology.com/myct/assignmentPrintView?displayMode=studentView&assignmentID=3451230 Page 269 of 300 HW 02: Animal Form & Function 5/13/15 4:53 PM Part E Is this statement supported or not supported by the graph? World-class sprinters are born with a higher percentage of fast and intermediate muscle fibers than other people have. ANSWER: supported not supported cannot be determined from the graph Correct Part F Is this statement supported or not supported by the graph? To train as a middle-distance runner, an average person should increase the percentage of slow fibers at the expense of fast fibers. ANSWER: supported not supported cannot be determined from the graph Correct Chapter 50 Question 1 Part A Which of the following sensory receptors is incorrectly paired with its category? ANSWER: taste receptor-chemoreceptor rod-electromagnetic receptor muscle spindle-mechanoreceptor olfactory receptor-electromagnetic receptor hair cell-mechanoreceptor Correct Chapter 49 Question 1 Part A Wakefulness is regulated by the reticular formation, which is present in the ANSWER: https://session.masteringbiology.com/myct/assignmentPrintView?displayMode=studentView&assignmentID=3451230 Page 270 of 300
