Environmental Biology Final Exam Questions
and Answers with Verified Solutions | Latest
Updated 2026
Definition of Science The systematic study of the physical and
natural
world through observation,
experimentation, and
testing to understand how it operates
What is the scientific method? A systematic process for investigating
phenomena,
acquiring new knowledge, or correcting
and
integrating previous knowledge.
What are control groups in Groups in an experiment that do not
experimental design? receive the
treatment or intervention, used as a
benchmark to
measure how the other tested groups do.
What are test groups in Groups that receive the treatment or
experimental intervention in
design? an experiment, allowing researchers to
observe the
effects of the treatment.
,What is a dependent variable? A dependent variable is the variable being
tested
and measured in an experiment, which is
affected
by changes in the independent variable.
What is an independent variable? An independent variable is the one that is
changed
or controlled in a scientific experiment to
test its
effects on the dependent variable.
Where is the dependent variable The dependent variable is typically plotted
located on a graph? on the
y-axis of a graph.
Where is the independent variable The independent variable is typically
located on a graph? plotted on
the x-axis of a graph.
Atomic Structure The arrangement of protons, neutrons, and
electrons in an atom, defining its properties
and
behavior.
Ionic Bonds Chemical bonds formed through the
transfer of
electrons from one atom to another,
resulting in
oppositely charged ions that attract each
other.
, Covalent Bonds Chemical bonds formed when two atoms
share
one or more pairs of electrons, creating a
stable
balance of attractive and repulsive forces.
Water's Polarity Water molecules have a partial positive
charge on
one side and a partial negative charge on
the
other, allowing for hydrogen bonding and
unique
properties.
Hydrogen Bonding Weak attractions between the hydrogen
atom of
one water molecule and the oxygen atom
of
another, contributing to water's high
surface
tension and boiling point.
Properties of Water Includes high specific heat, cohesion,
adhesion,
and the ability to dissolve many
substances, making
it essential for life.
Macromolecules Large, complex molecules essential for
life,
including carbohydrates, proteins, lipids,
and
nucleic acids.
