Pre-Lab Questions
1. What is a model organism, and why is Saccharomyces cerevisiae so often used as one?
In microbiology, molecular biology, and biochemistry labs, a model organism is utilized
for analysis and research. Saccharomyces cerevisiae is frequently used as one because
it is small (in sizo), has a fast growth rate, is inexpensive, and is safe and simple to work
with. It is critical for the role of yeast in a variety of foods and beverages, including
breads, wine, and beer..
2. Research and discuss the properties of mold that make them sometimes beneficial to humans,
and sometimes potentially harmful.
Mold has the ability to be both beneficial and detrimental to humans. Mold provides
benefits in the form of citric acid, which is employed in drugs such as those for the
neurological system, drug testing, and malignancies. Humans and animals can be
harmed by aspergillus, which can cause serious infections and create poisons when
inhaled
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.
Microbiologists have investigated the many vehicles/hosts/vectors, they can and have
helped to minimise the frequency of parasitic helminth infections, as well as diagnostics
and treatments. They've discovered the characteristics of the diagnosis and how to

prevent transmission through improved hygiene, immunizations, and adequate drinking
water cleaning

Post-Lab Questions
1. Which condition produced the most mold growth? The least? The fastest? The slowest?
The bright lemon environment created the most mould development, whereas Dark
control generated the least. Bright vinegar was the fastest, whereas dark water was the
slowest.
2. What was the purpose of examining three pieces of bread and three pieces of apple in each
treatment?
The goal of studying three slices of bread and three pieces of apple in each treatment
was to determine which conditions were most conducive to mould growth
