flat, convex, or raised - CORRECT ANSWER✔✔-descriptions of the
| | | | | | | | |
colony elevation
|
uniform fine turbidity - CORRECT ANSWER✔✔-a motile bacterium
| | | | | | | |
might exhibit this in liquid culture
| | | | |
pellicle growth - CORRECT ANSWER✔✔-bacterial type forming a thick
| | | | | | | | |
floating mass of cells on the surface of a liquid culture
| | | | | | | | | |
pellicle growth - CORRECT ANSWER✔✔-bacterial type forming a thick
| | | | | | | | |
floating mass of cells on the surface of a liquid culture
| | | | | | | | | |
sediment - CORRECT ANSWER✔✔-mass of bacterial cells setting at the
| | | | | | | | | |
bottom of liquid culture tube
| | | |
the fact that the microorganisms are ubiquitous means that they... -
| | | | | | | | | | |
CORRECT ANSWER✔✔-are found almost everywhere on earth
| | | | | |
, The results of lab exercise 2-1 shown below are, among others, the
| | | | | | | | | | | |
reason why - CORRECT ANSWER✔✔--aseptic technique methods were
| | | | | | | |
developed.
-you would disinfect the microbiology lab countertop prior to working in
| | | | | | | | | |
that space.
| |
- hand washing is important
| | | |
When growing bacteria, the choice of solid media (agar slant or agar
| | | | | | | | | | | |
plate) or liquid media depends on what you wish to accomplish; each of
| | | | | | | | | | | | |
the three types is best suited for a particular purpose. Evaluate the
| | | | | | | | | | | |
following and choose the one which is incorrect; i.e., the medium type
| | | | | | | | | | | |
does not match its correct function. - CORRECT ANSWER✔✔-best for
| | | | | | | | | |
pure culture determination: solid- agar slant medium
| | | | | |
A mixed culture does not necessarily a contaminated culture - CORRECT
| | | | | | | | | | |
ANSWER✔✔-true
Colony size, color, and shape are important factors used to describe
| | | | | | | | | | |
bacterial growth. What other physical factor should be included in the
| | | | | | | | | | |
description since it can influence the growth characteristics? - CORRECT
| | | | | | | | | |
ANSWER✔✔-- incubation temperature | | |
- duration of incubation
| | | |
- type of growth medium used
