Questions and CORRECT Answers 100% Correct (verified)
Question 1.
True or False: A virus is considered a microorganism
Correct Answer: false
Question 2.
what is the smallest biological unit of life?
Correct Answer: cell
Question 3.
At a generalized level, all cells are comprised of what?
Correct Answer: macromolecules
Question 4.
Animalia, plantae, Fungi, and protista are all classification under what type of organism?
Correct Answer: Eukarya
Question 5.
True or false: all multicellular microorgansims classified as animalia are autotrophic
Correct Answer: false
Question 6.
Microorganisms classified as ______ obtain most of their energy by converting light
energy into chemical energy
Correct Answer: plantae
Question 7.
Define catabolism
Correct Answer: the breakdown of complex molecules in living organisms to
form simpler ones, together with the release of energy; destructive
metabolism.
Question 8.
Upon cellular injury, which metabolic process is involved during the growth and repair
phases of the cell?
, Correct Answer: The anabolic process would be active as it is involved in the
building up of small complexes into larger ones
Question 9.
What is one of the main functions of light reactions?
Correct Answer: Similar to the electron transport chain, one of its main
functions is to generate a proton concentration gradient to generate ATP.
Question 10.
True of false: Dark reactions can occur in the presence or absence of light
Correct Answer: true
Question 11.
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?
Correct Answer: iris diaphragm What is the total magnification (relative to the
eye) of a sample imaged with a 60x objective and a 10x eyepiece? show your
math -✓✓60 x 10 = 600x magnification
Question 12.
Identify what type of electron microscope was used to capture the following image and
explain your choice.
Correct Answer: The image was captur4ed using a scanning electron
microscope (SEM). The above image shows the trademark shell image (no
subcellular organelles are visible) reminiscent of SEM. Only TEM is capable of
visualizing subcellular structures.
Question 13.
True or false: LB agar is classified as a selective, non-differential media
Correct Answer: false
Question 14.
What is agar used for in microbiology?
Correct Answer: Agar is used to create a solid, smooth surface on which
microbes can grow.
Question 15.
True or false: when performing a dilution streak a new (or sterilized) loop is not required
for each phase as long as the bacterial culture is pure
