“Pre-Lab Questions”
1. What is a model organism, and why is Saccharomyces cerevisiae so often used as one?
A model organism is a non-human species that has been thoroughly studied in order to
get a better understanding of specific biological processes, with the hope that
discoveries gained in the model organism can help scientists comprehend the workings
of other creatures. Saccharomyces cerevisiae is frequently utilized as a model organism
because it is not only simple and affordable to cultivate in the lab, but also because its
cells are uniform in size and expand solely in length, making cell growth easier to track.
2. Research and discuss the properties of mold that make them sometimes beneficial to
humans, and sometimes potentially harmful.
Molds can benefit humans in a variety of ways. Mold decomposes dead material and
returns them to the ecosystem, we eat some types of mold like mushrooms, and we
create medications like penicillin from mold. Molds can cause chronic coughing and
sneezing, eye discomfort, persistent headaches, and irritation of the throat and nose in
people. Mold can cause an allergic reaction in extreme cases, resulting in nausea,
vomiting, and pulmonary and nasal hemorrhage.
3. Parasitic helminths are a major cause of disease in undeveloped countries around the
world. Discuss the role that microbiologists can and have played in helping to reduce
the number of infections caused by parasitic helminths. After doing some
investigation, I discovered that the number of parasitic helminth illnesses had really
increased. Specific drugs are used to treat various infections, depending on the type of
infection. Treatments for other symptoms caused by the illness, such as fluids for
