What is another name for a liquid growth media, and what are
the basic components? - correct answer-Growth media in a
liquid form is often referred to as nutrient broth. As the name
implies its composition consists primarily of essential
'ingredients' such as a rich source of sugars, amino acids, and
vitamins. Together, a nutrient broth provides the microbe with a
source of carbon/energy, which, in turn, encourages its
expansion.
What is selective media? - correct answer-Selective media
allows for only the growth of certain microbes while restricting
the growth of all others.
What is differential media? - correct answer-Differential media is
used to distinguish between two (or more) related microbes.
, What are the requirements of a fastidious microbe? - correct
answer-A fastidious microbe is an organism with complex
growth requirements such that if absent it will not grow.
Enriched medias thus contain these specific and essential
nutrients required for the growth of a particular subset of
microorganisms.
What is agar? - correct answer-In its simplest form agar is liquid
growth media that has had a hardening agent added to it. Agar
is created when a polysaccharide derived from seaweed (algae)
extract is added to growth media. Agar is used to create a solid,
smooth surface on which microbes can grow.

True

LB agar is non-selective and non-differential
What are the three forms of hemolysis found on blood agar

Alpha hemolysis - correct answer-Presents with greenish-brown
color on blood agar due to the partial lysis of red blood cells
