WGU C190 BIOLOGY CERTIFICATION
PREPARATION GUIDE
◉ Biology
Answer: is the scientific study of life and is the branch of science that
studies living organisms and the way organisms interact with their
environments.
◉ To be considered alive, something must be made up of 5 distinct
qualities:
Answer: -Be made of materials organized in a hierarchical pattern.
-Use energy and raw materials to survive.
-Sense and respond to changing environments and maintain internal
stability, or homeostasis.
-Grow, develop, and reproduce.
-Be part of a population that evolves.
◉ cell
Answer: smallest living organism that shows all 5 characteristics of
life
◉ Matter
,Answer: any substance that has mass and takes up space.
◉ All matter can be classified in one of two categories:
Answer: biotic (living or having lived) or abiotic (nonliving and
never having been alive).
◉ biotic
Answer: living or having lived
◉ abiotic
Answer: nonliving and never having been alive
◉ Atom
Answer: basic unit of matter
◉ molecule
Answer: a chemical structure consisting of at least two atoms held
together by a chemical bond
◉ Macromolecules
Answer: biologically important molecules that are technically
polymers
,◉ When macromolecules are used as building blocks to form a
membrane-bound sphere
Answer: you have a cell
◉ two main types of cells
Answer: prokaryotes and eukaryotes
◉ prokaryotes
Answer: small and simple; they do not have any clearly defined
compartments inside of them
◉ eukaryotes
Answer: include membrane-bound organelles
◉ organelles
Answer: compartments inside the cell that contain specific groups of
macromolecules and carry out specific cellular functions
◉ microorganisms
Answer: Single-celled life forms
, ◉ Tissues
Answer: formed when similar cells work together to fulfill the same
detailed function
◉ Organs
Answer: collections of tissues that work together to carry out a
common general function
◉ organ system
Answer: a higher level of organization that consists of functionally
related organs
◉ Organisms
Answer: individual living entities that survive and reproduce as a
unit
◉ population
Answer: consists of all the individuals of a species living within a
specific area
◉ populations can interact with each other in positive and negative
ways, and together they form a
Answer: community
