(10 points) VERSION 2 Question 1 Which of the following is not a microscopic organism that Leeuwenhoek was able to observe under the microscope he constructed in 1674? Algae Bacteria Archaea Correct! Viruses Small multicellular animals Chapter 1, The Early Years of Microbiology section Question 2 The swan-necked flasks of Pasteur’s experiments _____. allowed for airflow without allowing the introduction of environmental microbes turned the flask cloudy contributed to supporting the theory of spontaneous generation allowed the flasks to temporarily turn cloudy and then become clear after a period of time You Answered All of the above Chapter 1, The Golden Age of Microbiology section Question 3 Which of the following is a practical application of the use of Saccharomyces cerevisiae? To distill water You Answered To make yogurt To make beer To make cheese To treat yeast infections Chapter 1, The Early Years of Microbiology section Question 4 Which of the following scientists provided evidence in favor of the concept of spontaneous generation? Needham Redi Spallanzani Buchner You Answered Pasteur Chapter 1, The Golden Age of Microbiology section Question 5 Which of the following statements is not true about endospores? Correct! They are reproductive structures. They are formed by the Clostridium species. They may be classified as central, subterminal, or terminal. They are formed when conditions are suboptimal. Endospore-forming bacteria cause tetanus and anthrax. Chapter 11, General Characteristics of Prokaryotic Organisms section Question 6 Which of the following is not an example of an archaea? An organism isolated from the Dead Sea An organism producing methane in ocean sediments An organism found in deep-sea hydrothermal vents You Answered An organism isolated from hot springs An organism causing pneumonia in an elderly person Chapter 11, Survey of Archaea section Question 7 Which of the following statements concerning prokaryotic flagella is false? You Answered Prokaryotic flagella can rotate 360 degrees. A "run" results from counterclockwise movement of the flagellum. Prokaryotic flagella are composed of tubulin. Treponema is an example of a bacterium that has an endoflagellum. Prokaryotic flagella are anchored to the cell wall by means of the basal body.
