BIOD 171 Module 1 Review questions
and verified answers
What is the study of microbiology? - correct answer ✅Microbiology is the study
of microbes (microorganisms and viruses) and their biological processes
What is the primary focus of clinical microbiology? - correct answer ✅ Pathogens
What is the smallest biological unit of life? - correct answer ✅
Cell
What is a macromolecule? - correct answer
composed from smaller subunits
✅ A complex molecule that is
What are the four main types of macromolecules? - correct answer
nucleic acids, lipids, carbohydrates
✅ Proteins,
What various functions do proteins have in a cell? - correct answer ✅
Proteins
my facilitate the movement of materials in or out of a cell. Some can act as
enzymes that catalyze, or speed up, biochemical processes. Others play a
structural role while other proteins, such as filaments, enable movement
✅
What are the two major types of nucleic acids and their roles? - correct answer
There are two major types of nucleic acids: DNA (deoxyribonucleic acid) and
RNA (ribonucleic acid). Nucleic acids are chemical molecules that carry genetic
information within the cell. DNA contains a vast amount of hereditary information
and is responsible for the inheritable characteristics of living organisms. RNA is
responsible for deciphering the hereditary information in DNA and using it to
synthesize proteins

✅
What is the plasma membrane, and what is it made up of? - correct answer
The plasma membrane serves the cell as a surrounding barrier that separates
the inside of the cell from the outside surrounding environment. The plasma
membrane also restricts movement of materials (water, nutrients, etc) either in or
out of the cell, thus allowing a cell to absorb and keep what is needed (influx)
while also preventing the escape (outflux) of essential nutrients. The plasma
membrane is composed of lipids (hydrophobic hydrocarbons)
✅
What are the three main components of carbohydrates? - correct answer
Carbon, hydrogen, and oxygen
correct answer ✅
What is the primary difference between prokaryotic and eukaryotic cells? -
Eukaryotic cells contain a nucleus, a membrane enclosed
region within the cell that contains the genetic material. Prokaryotic cells do not
have a nucleus and can be further classified as either bacteria or archaea
What are the main morphologies of bacteria? - correct answer ✅ Coccus
(round/spherical), bacillus (rod), vibrio (curved rod), spirillum (spiral/corkscrew)
harsh conditions? - correct answer ✅
Which group (classification) of microbes is noted for its ability to survive under
Archaea. They are able to survive in
extremely harsh environmental conditions such as high salt levels, acid conditions,
high temperatures, and oxygen-poor conditions
What are the four main classifications of Eukarya? - correct answer
plantae, fungi, or protista
✅ Animalia,
