EDITION EXAMINATION TEST 2026 COMPLETE
QUESTIONS AND SOLUTIONS GRADED A+
◉ The method of removing vegetative microbial life forms and
debris to reduce contamination to safe levels is termed_________.
sanitization
◉ the ______are drugs that deposit in developing teeth and cause
permanent brown discoloration tetracylcines
◉ Surfactants work by
A. Coating the organism preventing interaction with its environment
B. Blocking transport into the organism
C. Blocking transport out from the organism
D. Disrupting membrane integrity
E. All of the choices are correct disrupting membrane integrity
◉ which of the following microbial forms has the highest resistance
to physical and chemical controls? bacterial endospores
, ◉ a microorganism that does not have catalase or superoxide
dismutase would find it difficult to live in an environment with _____
oxygen
◉ What type of mutation alters the base, but not the amino acid
being coded for? silent
◉ movement of substances from lower to higher concentration
across a semipermeable membrane that must have a specific protein
carrier and cell expenditure of energy is called_____ active transport
◉ all_consist of a thiazolidine ring, a beta-lactam ring, and an R
group Penicillins
◉ How do sulfonamides work? inhibit folic acid synthesis
◉ Base pairs in DNA are held together by _____ bonds. hydrogen
◉ Cultures of a bacterial species were incubated out on the
incubator shelf, in an anaerobic jar and in a candle jar. After
incubation there was moderate growth of cultures in the candle and
anaerobic jars, but heavy growth of the culture on the incubator
shelf. This species is a/an facultative anaerobe
