BIOS242 EXAM 2026 COMPLETE
QUESTIONS WITH SOLUTIONS
◉Public Health Microbiology and Epidemiology. Answer: Oversees
and manages the dissemination of diseases within societies.
◉Immunology. Answer: Delves into the network of defensive
elements and cells generated as a reaction to infection.
◉Industrial Microbiology. Answer: Ensures the safety of our food
and water supply. It uses biotechnology which harnesses microbial
metabolism to produce a wide array of desired products, such as
bread, biofuels, and gene therapy.
◉Agricultural Microbiology. Answer: Revolves around the
interactions between microorganisms and cultivated plants and
domesticated animals.
◉Environmental Microbiology. Answer: Investigates how
microorganisms inhabit the varied ecosystems of our planet.
◉Louis Pasteur. Answer: Used swan neck flasks to disprove
spontaneous generation and that microorganisms are responsible
for disease.
, ◉Antonie van Leeuwenhoek. Answer: Created simple microscopes
capable of 300X magnification. Used these microscopes to observe
'animalcules' in dental plaque and pond water.
◉Robert Koch. Answer: Developed four postulates that must be met
to prove a microbe causes a specific disease.
◉Carl von Linne. Answer: Developed a taxonomic system for naming
living organisms and grouping similar organisms together.
◉Binomial System of Nomenclature. Answer: Combination of the
genus and species name. The genus name is written first and the
first letter is capitalized. The species name is written second and
begins with a lowercase letter. Both names are typed in italics.
◉Bright field light microscope. Answer: This microscope forms an
image when light is transmitted through the specimen. The
specimen absorbs some of this light, and the rest is transmitted to
the objective lens into the field of vision. As a result, the specimen
will produce an image darker than the surrounding brightly
illuminated field.
◉Dark field light microscope. Answer: A bright-field microscope can
be adapted to this microscope by adding a special disc called a 'stop'
