Portage Learning BIOD171 Final EXAM Questions and
Answers 100% Correct 2025 Update
True or False: A virus is considered a microorganism.
| | | | | | | |
False. Viruses are not living and as such are not considered microorganisms. Viruses
| | | | | | | | | | | |
can, however, be classified as microbes, a more general term that includes
| | | | | | | | | | | |
microorganisms and viruses.
| | |
1. What is the smallest biological unit of life?
| | | | | | |
A cell.
| |
2. At |a |generalized |level, |all |cells |are |comprised |of |what?
Macromolecules*
|
*A student may also answer: Proteins, Lipids, Nucleic acids and Polysaccharides but
| | | | | | | | | | |
they must answer with all four to be fully correct.
| | | | | | | | | |
1. Which of the following microorganisms are considered to be Eukarya? Select all that
| | | | | | | | | | | |
| apply.
A. Animalia
B. Plantae
C. Fungi
D. Protista
A,B,C,D
|
,2. True |of |False: |All |multicellular |microorganisms |classified |as |Animalia |are
, heterotrophic.
True
3. Microorganisms |classified |as |Plantae |obtain |most |of |their |energy |by |converting
| energy into | | energy.
Light (sunlight); chemical (sugars)
| | | |
1. Define catabolism. |
Catabolism is the process of breaking down larger molecules into useful energy
| | | | | | | | | | |
sources.
|
2. Upon |cellular |injury, |which |metabolic |process |is |involved |during |the |growth |and
repair phases of the cell? The anabolic process would be active as it (by definition) is
| | | | | | | | | | | | | | | |
involved in the building up of small complexes into larger complexes.
| | | | | | | | | | |
1. In phosphorylation, the light reactions always occur where?
| | | | | | |
The process of converting light energy into chemical energy
| | | | | | | | |
(photophosphorylation) always occurs in the membrane.
| | | | | |
2. True |or |False: |The |Calvin |cycle |must |occur |in |the |absence |of |light.
False. The term ‘dark reactions’ (also known as the Calvin Cycle) simply denotes the
| | | | | | | | | | | | |
second stage in photosynthesis—dark reactions do not actually require darkness in
| | | | | | | | | | |
order to occur.
| | |
, 1. 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.
| | | | | | | | | | | | |
Select all that apply.
| | | |
A. |Objective
B. |Condenser
C. |Iris |diaphragm
D. |Eye |piece
C. The iris controls the amount of light that passes through the sample and into the
| | | | | | | | | | | | | | |
objective lens. Thus, it can be adjusted (opened or closed) to alter the amount of
| | | | | | | | | | | | | | |
light.
|
2. What |is |the |total |magnification |(relative |to |your |eye) |of |a |sample |imaged |with |a
60x objective and a 10x eyepiece? Show your math.
| | | | | | | | |
60 x 10 = 600x magnification
