microbio portage final exam/2025 easy pass
What is the total magnification (relative to your eye) of a sample imaged with a 60x objective
and a 10x eyepiece? - 600x magnification
The number of phases (3 vs. 4) and/or the number of times a loop passes through a previous
phase (once vs. multiple times) is acceptable provided what happens? - Well Either
deviation is
acceptable in practice as long as the resulting gradient contains within it the growth of
individual
colonies. Otherwise, the experiment need to be repeated.
All multicellular microorganisms classified as Animalia are autotropic. - false
Animalia, Plantae, Fungi and Protista are all classification under what type of organism? -
Eukarya
Assuming a constant (non-adjustable) light source power, identify the part of the microscope
you
would adjust to limit the amount of light entering the microscope. - iris
At a generalized level, all cells are comprised of what? - Macromolecules
childhood skin diseases near mouth/nose - impetigo
Define catabolism. - Catabolism is the process of breaking down larger molecules into
useful
, energy sources.
Define catabolism. - the process of breaking down larger molecules into useful energy
sources.
Describe the symptoms and treatment regimen for someone infected with Clostridium
perfringens. - symptoms : muscle
necrosis, swelling of infected areas, fever and intense gas production.
Treatment: removal
of infected tissue, with
heavy antibiotic therapies.
Described the main underlining differences between the Salk and Sabin polio vaccine. -
Salk - inactivated form of virus & injected
sabin- live weakned form & oral admin
Identify what type of electron microscope was used to capture the following image and explain
your choice. - Scanning Electron Microscope Because it is only showing the outside of the
cell and not showing
any subcellular organelles Shows shell image no organelles are visible.
infection occurs at the time of birth - ophthalmia neonatorum
infection of thin, transparent scleral tissue - conjunctivitis
