, RATIONALE
Microbiology encompasses the investigation of microorganisms, including bacteria, fungi, protozoa, and viruses, focusing on their structure,
function, and interactions within ecosystems. Understanding these microscopic entities is fundamental to fields such as medicine,
environmental science, and biotechnology.
Q2 QUESTION 2 OF 16
What is the smallest biological unit of life?
CORRECT ANSWER
the cell
RATIONALE
Cells are the fundamental structural and functional units of all living organisms, capable of carrying out life processes such as metabolism,
growth, and reproduction. This principle of cellular organization is foundational to biology, emphasizing that all life is composed of one or more
cells.
Q3 QUESTION 3 OF 16
What is a macromolecule?
CORRECT ANSWER
My answer: Macromolecules are large and complicated molecules that are made up of smaller molecules. Examples of macromolecules are
polysaccharides, lipids, nucleic acids, and proteins.
More info:
- Proteins are made up of amino acids (of which there are 20 different types).
- Nucleic Acids can be either DNA or RNA. Nucleic acids are made up of nucleotides. For DNA, the nucleotides are adenine (A), guanine
(G), cytosine (C) and thymine (T). For RNA, the nucleotides are adenine (A), guanine (G), cytosine (C) and uracil (U).
- Lipids are made up of hydrocarbons.
- Polysaccharides are made up of monosaccharides.
Answer Key: A macromolecule is classified as a complex molecule that is composed from smaller subunits.
RATIONALE
Macromolecules are characterized by their large size and complex structures, resulting from the polymerization of smaller subunits such as amino
acids in proteins or nucleotides in nucleic acids. This concept highlights the relationship between structure and function in biological systems,
emphasizing how the arrangement of smaller units leads to diverse macromolecular functions.
