WGU C190 INTRO TO BIOLOGY - UNIT 1
EXAM
Abiotic - Correct Answers -Non-living, may be within or made by a living organism.
Biotic - Correct Answers -Living. Matter is considered ______ if it was ever alive at
some point in time
Atom - Correct Answers -Smallest level. The basic unit of matter. Consists of a dense
nucleus surrounded by electrons.
Molecule - Correct Answers -Second level. A chemical structure consisting of at least
two atoms held together by a chemical bond.
Macromolecule - Correct Answers -Third level. Biologically important molecules that are
technically polymers. Example: DNA.
Development - Correct Answers -Structure and function change in an orderly way as an
organism passes through its life cycle. An individual's pattern of _______ is partly
determined by genetic instructions.
Reproduction - Correct Answers -Occurs when an individual organism passes on its
genetic information to a newly independent organism, or offspring.
Evolution - Correct Answers -A scientific theory that explains how and why life changes
over time. Provides the explanation for why all living organisms share profound
similarities, and yet, the life forms on our planet are so incredibly diverse.
Cell - Correct Answers -Fourth level. The fundamental unit of life. Essentially a tiny
droplet of water and other molecules enclosed by a fluid "skin" or membrane. The
smallest and simplest entity that possesses all the characteristics of life.
Organelle - Correct Answers -Fifth level. Compartments inside the cell that contain
specific groups of macromolecules and carry out specific cellular functions. it encloses
the DNA within the cell.
Microorganism - Correct Answers -Sixth level. Single-celled life form. Consists of just
one cell and include unicellular organisms such as bacteria and protists.
