CHAPTERS INCLUDED
Characteristic of all cellular organisms - ANSWER ✓Includes the abilities to
communicate, evolve, and move.

Pasteur flask - ANSWER ✓Features a swan neck design to prevent particles from
contaminating the contents.
,Pasteur's conclusions on spontaneous generation - ANSWER ✓He reasoned
that sterilizing the flasks would have confirmed the spontaneous generation
hypothesis if it were true.
Pure culture - ANSWER ✓A population composed entirely of identical cells.
Martinus Beijerinck - ANSWER ✓First to isolate green algae, certain nitrogen-
fixing bacteria from root nodules, and some sulfate-reducing bacteria.
Chemolithotrophy - ANSWER ✓Energy production through the oxidation of
inorganic compounds.
Developments in immunology and medical microbiology - ANSWER ✓Built
directly on the practical applications of Robert Koch’s research.

lipid synthesis for virus asembly.
Viral Aggregation - ANSWER ✓Clumping of viral proteins to form complete
nucleocapsids.

observe viruses.
Conservative Replication - ANSWER ✓Replication mechanism in which original
viral RNA strands remain intact.

from the host.
Viral Life Cycle - ANSWER ✓Complete sequence of events from virus entry to
progeny release.
,Founding Editors - ANSWER ✓Initial editors who established a key scientific
publication.

Wee animalcules - ANSWER ✓Term used by Antoni van Leeuwenhoek to
describe tiny living organisms.
Agar - ANSWER ✓Introduced as a solid medium by Walther Hesse and Robert
Koch.
Microbial control in wastewaters - ANSWER ✓Falls under the field of aquatic
microbiology.
Robert Koch's contributions to microbiology - ANSWER ✓Include creating the
tuberculin test, establishing four postulates to link specific microbes to diseases,
and using agar as a solid medium.
Mycobacterium tuberculosis staining difficulty - ANSWER ✓Caused by the
high content of waxy lipids in its cell wall.
