“Pre-Lab Questions”
1. What is a model organism, and why is Saccharomyces cerevisiae so often used as one?
a model organism is used in the lab to help us understand biological
processes. Saccharomyces is often used because it is fast-growing
2. Research and discuss the properties of mold that make them sometimes beneficial to humans,
and sometimes potentially harmful.
mold can be used in medication which is beneficial to our health and it is
very harmful when we inhale it.
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.
A microbiologist will be able to research different vechicles and identify the
causes and effects as well as possle cures. They will be able to diagnose
and help prevent the spread
