CLEP Natural Science Exam UPDATED
Study Guide QUESTIONS AND
CORRECT ANSWERS
Absolute Zero - CORRECT ANSWERS The theoretical temperature at
which partical motion stops; also known as 0 Kelvin
Acid - CORRECT ANSWERS A chemical that denotes protons (H+ions)
when dissolved in water
Active Transport - CORRECT ANSWERS Uses energy to move
molecules across a cell membrane against a concentration gradient.
Adipose Tissue - CORRECT ANSWERS found beneath the skill and
around organs, providing cushioning, insulation, and fat storage
aerobic - CORRECT ANSWERS steps in the cellular respiration process
that require oxygen
Alpha decay - CORRECT ANSWERS occurs when the nucleus of an
atom emits the package of two protons and two neutrons, called an alpha
particle, which is the equivelant to the nucleus of a helium atom
Alveioli - CORRECT ANSWERS thin walled air sacs which are site of
gas exchange
anbolism - CORRECT ANSWERS the process by which cells build
molecules and store energy
,anaerobic - CORRECT ANSWERS steps within the cellular respiration
process that do not require oxygen
anaphase - CORRECT ANSWERS when the centromere divides,
chromotids are separated from each other and become a chromosone, the two
identical chromosomes move along the spindle fibers to the opposite ends of the
cell
anions - CORRECT ANSWERS negative ions
Archimedes' principle - CORRECT ANSWERS when an object is placed
in a fluid, the object will have a buoyant force equal to the weight of the
displaced fluid
arteries - CORRECT ANSWERS large blood vessels that carry blood
away from the heart
Atmospheric pressure - CORRECT ANSWERS pressure that results in
the atmosphere exerting force on the earth; can be measured with a barometer
atom - CORRECT ANSWERS the simplest unit of an element that
reatains the element's characteristics.
Atomic Mass - CORRECT ANSWERS calculated by adding up the
masses of the protons and neutrons
Atomic number - CORRECT ANSWERS the number of protons found in
the nucleus of an atom of that element
atomic weight - CORRECT ANSWERS the average mass number
, B cells - CORRECT ANSWERS class of lymphocyte cells that merge
from the bone marrow mature and produce antibodies, which enter the blood
stream
base - CORRECT ANSWERS a chemical that accepts protons (H+ions)
when dissolved in water
beta decay - CORRECT ANSWERS occurs when the nucleus emits a
beta particle that degrades into an electron as it passes out of the atom
binomial nomenclature - CORRECT ANSWERS methodology proposed
by Linnaeus that used two Latin-based categories-genus and species-to name
each organism, which can be further classified based on family, order, class,
phylum, and kingdom
Biogeography - CORRECT ANSWERS the study of how photo-synthetic
organisms and animals are distributed in a particular location, plus the history of
their distribution in the past
biome - CORRECT ANSWERS an ecosystem that is generally defined
by its climate characteristics
biosphere - CORRECT ANSWERS part of the earth that includes all
living things
blood tissue - CORRECT ANSWERS flows throughout every blood
vessel and heart and is essential fo rcarrying oxygen to cells, fighting infection,
and carrying nutrients and wastes to and from cells
