2. serological testing (identifying markers)
3. genotype characteristics (genetic contents; important for
research)
microscopic morphology - ANSWER-size, shape, staining
characteristics
colony morphology - ANSWER-culture characteristics in petty
dish

Metabolic capabilities - ANSWER-what an organism eats and
breathes
dichotomous key - ANSWER-step by step approach to
identify an organism
using a series of paired
descriptions
biovar/serovar - ANSWER-variation within species (E. coli)
(Vibrio Cholerae)
bacterium size - ANSWER-10 micrometers
virus size - ANSWER-100 nanometers (electric microscope)
Light Properties - ANSWER-light/energy travels as a wave
(wavelength +
frequency)
Wavelength - ANSWER-The distance between two
corresponding parts of a
wave
,Frequency - ANSWER-the number of complete wavelengths that
pass a point in
a given
time
if wavelength goes up - ANSWER-frequency goes down/energy
goes down
if frequency goes up - ANSWER-energy goes up
reflection - ANSWER-The bouncing back of a wave when it
hits a surface
through which it
cannot pass.
Transmission - ANSWER-the passage of light through an object
absorption of light - ANSWER-the process by which matter
absorbs radiative
energy
Emmision of light - ANSWER-energy emitted back in diff
wavelength
, Refraction - ANSWER-The bending of light as it passes at an
angle from one
medium to
another
light (microscopy) - ANSWER-use of visible light as source of
energy
electron (microscopy) - ANSWER-use of electrons to visualize
immersion oil - ANSWER-oil placed on a slide to minimize
refraction of the light
entering the

(resolving power);
inversely related to
wavelength
