WGU D311 Microbiology Section 1 || 100% Accurate Answers.
Which statement describes prokaryotic cells? correct answers Prokaryotic cells are found in
coccus form in both pairs and clusters.
Which statement describes eukaryotic cells correct answers The nuclei of eukaryotic cells are
surrounded by complex nuclear membranes.
Which statement describes eukaryotic flagella? correct answers Eukaryotic flagella are flexible,
whip-like structures.
Which statement describes the endomembrane system? correct answers It includes the Golgi
apparatus, lysosomes, and vesicles.
Which statement accurately describes similarities between protozoa and fungi? correct answers
Both can be harmful or harmless depending on the context.
Why are algae considered photsynthetic organisms? correct answers Algae produce chemical
energy from the sun's light energy
Why are plasmids important to the survival of organisms? correct answers Plasmids carry genetic
material, apart from the genome, that can benefit the organism.
Which aspect of nutrient cycling is performed only by prokaryotes? correct answers Nitogen
fixation
Which microbial process is useful in the production of alcoholic beverages? correct answers
glucose fermentation
How does microbial bioremediation benefit the environment? correct answers By helping to
metabolize and remove pollutants in the atmosphere.
, How is penicillin classified? correct answers As a natural antibiotic
What describes the relationship of pathogens to virulence? correct answers Highly virulent
pathogens almost always lead to a disease state when introduced to the body.
What is the key difference between a primary pathogen and an opportunistic pathogen? correct
answers Primary pathogens can infect anyone, whereas opportunistic pathogens can cause
disease if the host is immunocompromised
How can disease expression be described? correct answers Signs and symptoms associated with
illness can be a result of many things, including an immune response.
What is the correct understanding of the median infectiouse dose? correct answers It is the
number of pathogenic cells required to cause active infection in 50% of inoculated animals.
Which structure aids in the evasion of phagocytosis by preventing immune cells from adhering to
pathogens? correct answers Capsule
Which group contains a pathogen that adheres to host cells by using a large adhesive disk?
correct answers Protozoans
A phenomenon found only in viruses, when a simultaneous infection occurs from two viruses
that share their genetic mutation inside of an infected host cell, resulting in a mixing of genes and
changes in the spike proteins. correct answers Antigenic shift
small antigenic changes that happen over time, resulting in mutations of the genes for surface
proteins neuraminidase and/or hemagglutinin correct answers Antigenic shift
Which structure is used by certain bacteria to adhere to host tissues? correct answers Type 1
fimbria adhesin
