,T/F: A virus is considered a microorganism - ANSWER-False.
Viruses are not living and are therefore not considered microorganisms. Viruses
can be classified as microbes (a more general term that includes microorganisms
and viruses).
What is the smallest biological unit of life? - ANSWER-A cell

macromolecules
How many different types of amino acids are available from which to make
proteins? - ANSWER-20
Define an essential amino acid. - ANSWER-An essential amino acid cannot be
produced by the human body and as such must be take in from the environment
through alternative sources (i.e) food.
Where can the two major types of nucleic acids be found in the cell and what are
their roles? - ANSWER-DNA and RNA can both be found in the nucleus, but only
RNA is able to leave the nucleus.
- DNA contains a large 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.
