Biology 3010 Final Exam Questions &
Answers (Grade A+)
What was the message we should learn from the experience of
Elizabeth Bugie, whom you researched as part of the Engage 2
(Unknown Microbiologists) assignment? -
correct answer ✅Why wasn't she given credit for her discoveries?
Are there certain groups of people whose work tends to be
ignored? What should we do about it?
Give a detailed explanation of why magnification is represented
with the letter, X. -
correct answer ✅both the numerator and the denominator have
the same units, so they cancel out, thereby yielding a number that
has no units. Therefore, we use the letter X to show the magnitude
of the ratio between the two measurements.
The first two tenets of Cell Theory were not published until 1838
despite the fact that the basic principles were discovered in the
1600's and 1700's; further, additional tenets were added in 1855,
1968, and even more recently, as new discoveries were made.
What important principle about the process of science can we learn
from the development of Cell Theory? -
correct answer ✅Its always changing as technology is advancing.
We are able to answer questions now that couldn't have been 200
years ago. We also make changes on things that we proved were

wrong to begin with and adjust it to something else that makes
more sense.
Antonie van Leeuwenhoek was mocked for his reports. He was
mocked for the language he used and he was mocked for the "wild"
claims he made relative to what he saw when he looked through his
microscopes. We now consider him to be the father of
microbiology. What principle do we learn about the process of
science from the example of Antonie van Leeuwenhoek? -
correct answer ✅The main idea here is that people who buck the
status quo tend to be mocked by the establishment but that
verification brings recognition and finally acceptance of the validity
of new discoveries.
What is a scanning electron microscope? -
correct answer ✅A microscope that relies on electrons to bounce
off a specimen
What is the best meaning of the tenet of Cell Theory which states
that cell activity depends on the activities of sub-cellular structures
within the cell? -
correct answer ✅Enzymes and substrates combine within
organelles to improve the efficiency of cellular processes

What is the best meaning of the tenet of Cell Theory which states
that all basic chemical and physiological functions are carried out
inside cells? -
correct answer ✅While an organism can respond to stimuli,
reproduce, move, etc., all the things done by that organism
ultimately start with chemical reactions that occur within the
bounds of the cell
If you observe a cell through a microscope that possesses a 5X
ocular lens and a 60X objective lens, and the resulting image shows
the cell as 2400 µm long, what is the size of the actual cell? (Your
answer will be assumed to be in µm; answer with a whole number
only, no units). -
correct answer ✅8
What is the total magnification of the microscope if the ocular lens
is 10X, the cell is 2 µm long, and the image shows the cell as 3500
µm long? (Answer with a number and the letter X with no space in
between [for example: 5X]) -
correct answer ✅17500x

Answers (Grade A+)
What would be the magnification of the ocular lens if the objective
lens was 30X, the specimen's image was 1650 μm, and the
specimen's actual size was only 5 μm? (Answer with a number and
the letter X with no space in between [for example: 5X]) -
correct answer ✅11x
Flagella are transparent, colorless, hair-like structures on the
surface of a cell that help the cell to move relative their its
environment. If you want to see the surface structure of a bacterial
flagellum, what type of microscope would you need to use? -
correct answer ✅Scanning electron microscope
Which tenet of cell theory justifies the study of yeast, such as
Saccharomyces cerevisiae, to learn about human cellular activities,
such as glycolysis, Kreb's Cycle, and the electron transport chain? -
correct answer ✅All cells are basically the same in chemical
composition and metabolic activities.
Before performing an examination, nurses and physicians wash
their hands with soap, lathering the fronts and backs of the hands
and scrubbing between fingers, for a minimum of 20 seconds
before rinsing with clean water. Which tenet of Cell Theory explains
why this is a crucial practice? -
correct answer ✅Cells only arise from pre-existing cells
