MIC 102 EXAM SCRIPT 2026 QUESTIONS WITH
ANSWERS GRADED A+
◉ Microorganisms. Answer: organisms that are too small to be seen
clearly with the unaided eye
◉ Multicellular microorganisms. Answer: microbes that are visible
without microscopes which are consists of small aggregations of cells
example bread molds and filamentous photosynthetic microbes
◉ Cellular microbes. Answer: are smaller than 1 millimeter in diameter
of then unicellular and if multicellular lacked differentiated tissues
◉ Microbiologists study. Answer: Cellular and Acellular organisms
◉ prokaryotic cell. Answer: Have an open floor plan, (their contents are
not divided into compartments by membranes (rooms)
◉ Eukaryotic cells. Answer: have a nucleus and other membrane bound
organelles (mitochondria, chloroplasts) that separate some cellular
materials and processes from others.
,◉ Three Domains. Answer: Bacteria, Archaea, Eukarya
◉ How old is our planet. Answer: Dating meteorites through the use of
radioisotopes places our planet at an estimated 4.5 to 4.6 billion years
old
◉ catalytic proteins. Answer: are enzymes and structural proteins serve a
myriad of functions such as transport, attachment and motility.
◉ rRNA comparison. Answer: important role in classification of
microbes
◉ LUCA. Answer: last universal common ancestor ( LUCA is in the
bacterial branch the other branches evolved independently)
◉ Feature of microbiology ( pure or axenic culture ). Answer:
microbiologists often remove microorganisms from their normal habitats
and grow them isolated from other microbes
◉ MIcrographia(book). Answer: Robert Hooke
◉ Antony van Leeuwenhoek (1632-1723). Answer: constructing simple
microscopes composed of double convex glass lenses held between two
silver plates. his microscopes could magnify about 50 to 300 times.
, ◉ spontaneous generation. Answer: Hypothesis stating that life could
arise from nonliving matter.
◉ Idea of microorganisms cause disease. Answer: began in early
nineteenth century from diverse fields 19th.
◉ Koch's Postulates theory (Koch 1905 awarded Nobel prize). Answer:
a sequence of experimental steps for directly relating a specific microbe
to a specific disease
◉ Koch's Postulates difficalites. Answer: The application not always
feasible. ex, viruses, and organisms that must live within host cells such
as Mycobacterium leprae the causative cause of leprosy cannot be
isolated in pure culture furthermore microbiologists used molecular and
genetic evidence.
◉ Medical Microbiology. Answer: diseases of humans and animals
(Medical Microbiology investigates agent causing infectious diseases
and measures for their control and elimination. involving in tracking
unidentified pathogens such those causing hantavirus pulmonary
syndrome, west nile encephalitis middle east respiratory syndrome.
◉ Which entities are included as microorganisms?. Answer: Organisms
and acellular biological entities
