MICROBIOLOGY LAB CUMULATIVE FINAL - BACHOON ||
ALL ANSWERS ARE VALID.
disease causing microbes are ____________ correct answers everywhere
any technique designed to keep unwanted microorganisms from contaminating sterile materials
- Ex. burning inoculated loop & not placing bacterial tube cap onto table correct answers aseptic
technique
plates are always incubated in an __________ __________ _________ correct answers inverted
inoculated postion
part of the body which is supposed to be devoid of bacterial flora; when infected it causes serious
illness such as meningitis correct answers cerebrospinal fluid
uses a series of magnifying lenses to increase the size and illumination of very small specimens
correct answers compound microscope
these are much smaller than bacteria correct answers viruses
this is achieved through the use if both the objective lense as well as the ocular lens correct
answers total magnification
this results in a loss of light collected by the lenses, and acts to decrease the resolution or clarity
of the image correct answers refraction
used in carrying the microscope and houses the light source correct answers base
provides illumination to the specimen correct answers light source
, platform which the specimen rest on correct answers stage
is used with with scan and low power objective lenses correct answers coarse adjustment knob
used with high dry and oil immersion objective lenses correct answers fine focus
allows the movement of the stage from left to right and forward to backward correct answers
mechanical stage adjusters
collects and concentrates light emitted from the light sources into tight beam before passing it
through the specimen correct answers condenser
located within the condenser; tightens or widens the beam of light emitted for the condenser
correct answers iris diaphragm
serve to magnify the specimen part correct answers objective lenses
4x magnification correct answers scan
10x magnification correct answers low power
40x magnification correct answers high dry power
100x magnification correct answers oil immersion
this determines the type of antibiotics that need to be used correct answers cell morphology and
arrangement
