You are observing two cells under the microscope. They are the same type of
eukaryotic cell but one appears much larger. Based on appearance alone, which one
would you expect to be carrying out respiration at a more active rate, the larger or
smaller cell? Explain why.ANS I believe it is the smaller cell that will breathe at a more
active rate because in order for respiration to occur efficiently and more actively the
surface area to volume ratio is very critical; also, if the larger surface area is present
then the diffusion of gases occur at a higher rate; so, larger cells will have a smaller
surface to volume ratio and diffusion that will occur at a slower rate creating a less
active respiration; and, on the other hand smaller cells will have a larger surface area to
volume ratio and an improved diffusion rate, so the higher rate and more active
respiration.
The smaller cell. Cells need to remain relatively small because as a cell expands the
amount of surface area relative to the volume of the cell decreases. The smaller cell is
more active because relative to its volume, its surface area is larger than a bigger cell.
With a larger surface area (relative to its volume) this allows the metabolic processes to
occur faster.

Explain what happens to the epiglottis during swallowing. Why?ANS During swallowing
the epiglottis moves inferiorly to close off and prevent aspiration by covering the trachea
and creating a passage for liquid, food, or bolus into the esophagus; and, preventing
these things from entering into the lungs.
Air and food pass in which one of the following areas:ANS Oropharynx
Label the following five items from the diagram:
Label B- ___________
Label D- __________
Label E- __________
Label F- __________
Label G- __________ANS B - Oral Cavity
D - Epiglottis
E - Glottis
F - Trachea
G - Esophagus
From widest to narrowest, the branches of the bronchial tree are:ANS Primary bronchi,
secondary bronchi, tertiary bronchi, bronchioles
Explain why someone who has hypergastrinemia (excessive secretion of gastrin) might
develop gastric/stomach ulcers.ANS Hypergastrinemia leads to excess secretion of the
gastrin hormone, which induces excess secretion of hydrochloric acid in the stomach;
and, the excess acid then acts as a protective mucousa layer causing disruption that
can lead to those ulcers.
Gastrin stimulates the secretions of pepsinogens and hydrochloric acid. Excess
amounts would lead to erosion of the stomach lining.
Look carefully at the diagram below. Label the following 5 organs of the digestive
system.
To receive credit for the intestines you must label the specific region.
3: ___________
4: ___________
7: ___________
9: ___________
10: ___________ANS 3. Stomach
4. Gallbladder
7. Jejunum
9. Appendix
10. Rectum
