This pathogen is classified as a: a) Prokaryote b) Eukaryote c) Virus d) Prion Answer: a Rationale: S. aureus is a bacterium, which is prokaryotic. Bloom’s: Application 1.4 Which domain includes organisms that are prokaryotic and often found in extreme environments? a) Bacteria b) Archaea c) Eukarya d) Protista Answer: b Bloom’s: Knowledge 1.5 All of the following are true about viruses EXCEPT: a) They are acellular b) They can replicate independently c) They contain genetic material d) They require a host cell to multiply Answer: b Bloom’s: Comprehension 1.6 The scientist credited with first observing "animalcules" under a microscope was: a) Robert Koch b) Louis Pasteur c) Antonie van Leeuwenhoek d) Joseph Lister Answer: c Bloom’s: Knowledge 1.7 Koch’s postulates are used to: a) Classify bacteria b) Determine the cause of an infectious disease c) Sterilize medical equipment d) Grow viruses in culture Answer: b Bloom’s: Comprehension 1.8 Which of the following is a major limitation of Koch’s postulates? a) They cannot be applied to viruses b) They require pure culture, but some microbes cannot be grown in vitro c) They are only valid for fungal diseases d) They require animal testing Answer: b Bloom’s: Analysis 1.9 The term "spontaneous generation" was disproven by: a) Jenner b) Pasteur c) Ehrlich d) Fleming Answer: b Bloom’s: Knowledge 1.10 Pasteur’s swan-neck flask experiment showed that: a) Microorganisms arise spontaneously from broth b) Microorganisms are present in air and can contaminate sterile broth c) All microbes are harmful d) Boiling kills all life forms Answer: b Bloom’s: Comprehension 1.11 The development of aseptic surgery is credited to: a) Semmelweis and Lister b) Koch and Pasteur) Jenner and Snow d) Ehrlich and Metchnikoff Answer: a Bloom’ Knowledge 1.12 Which of the following is an example of a prokaryotic cell? a) Yeb) Amoeba c) Escherichia coli d) Human skin cell Answer: c Bloom: Application 1.13 All cellular organisms fall into one of three domains. Which domain includes humans? a) Bacteria b) Archaea c) Eukarya d) Protista Answer: c Bloom’s: Knowledge 1.14 A microbiologist is studying a sample from a hot spring. The organisms are prokaryotic and have cell walls lacking peptidoglycan. They likely belong to: a) Bacteria b) Archaea c) Fungi d) Algae Answer: b Rationale: Archaea have unique cell wall compositions, often lacking peptidoglycan. Bloom’s: Analysis 1.15 Which of the following is NOT a major group of microorganisms? a) Algae b) Helminths c) Protozoa d) Ferns Answer: d Bloom’s: Comprehension 1.16 The human microbiome refers to: a) All pathogenic microbes in the body b) The collection of microbes living on and in the human body c) Only bacteria in the gut d) The study of microbial genetics Answer: b Bloom’s: Knowledge 1.17 Disruption of the normal microbiome (dysbiosis) has been linked to all of the following EXCEPT: a) Obesity b) Inflammatory bowel disease c) Type 1 diabetes d) Fractured bones Answer: d Bloom’s: Comprehension 1.18 Which of the following is a beneficial role of microorganisms? a) Causing food spoilage b) Producing antibiotics c) Spreading epidemics d) Degrading pollutants Answer: b Bloom’s: Comprehension 1.19 Bioremediation uses microorganisms to: a) Cause disease b) Clean up environmental pollutants c) Produce vaccines d) Ferment food Answer: b Bloom’s: Knowledge 1.20 The concept of "One Health" emphasizes the interconnection between: a) Human, animal, and environmental health b) Bacteria, viruses, and fungi c) Hospital, clinic, and laboratory d) Prokaryotes, eukaryotes, and viruses Answer: a Bloom’s: Comprehension 1.21 Which of the following is an example of a recombinant DNA technology application? a) Pasteurization of milk b) Production of human insulin by E. coli c) Gram staining of bacteria d) Isolation of a pure culture Answer: b Bloom’s: Application 1.22 The CRISPR-Cas system is a: a) Bacterial defense mechanism against viruses b) Type of microscope c) New antibiotic d) Method for staining endospores Answer: a Bloom’s: Knowledge 1.23 All of the following are true about prions EXCEPT: a) They are composed of protein b) They contain nucleic acid c) They cause transmissible spongiform encephalopathies d) They are resistant to standard sterilization methods Answer: b Bloom’s: Comprehension 1.24 The smallest known infectious agents are: a) Bacteria b) Viruses c) Prions d) Fungi Answer: c Bloom’s: Knowledge 1.25 Which of the following statements about microbial growth is correct? a) Most bacteria grow optimally at 37°C b) All microbes require oxygen for growth c) Viruses grow on agar plates d) Fungi cannot grow at room temperature Answer: a Bloom’s: Comprehension 1.26 A patient’s wound culture grows a bacterium that forms a thick, sticky layer on the agar. This property is characteristic of: a) Biofilm formation b) Motility 1.27 Biofilms are medically significant because they: a) Are easily killed by antibiotics b) Protect bacteria from the immune system and antimicrobials c) Only form on non-living surfaces d) Are composed solely of viruses Answer: b Rationale: Biofilms provide a protective matrix that resists antibiotics and host defenses, causing chronic infections. 1.28 Which of the following is a current application of microbial genomics? a) Identifying new antibiotic resistance genes b) Determining the age of fossils c) Measuring atmospheric pressure
