CLEP Natural Science Exam UPDATED
ACTUAL Questions and CORRECT
Answers
Absolute Zero - CORRECT ANSWER - The theoretical temperature at which partical
motion stops; also known as 0 Kelvin
Acid - CORRECT ANSWER - A chemical that denotes protons (H+ions) when dissolved
in water
Active Transport - CORRECT ANSWER - Uses energy to move molecules across a cell
membrane against a concentration gradient.
Adipose Tissue - CORRECT ANSWER - found beneath the skill and around organs,
providing cushioning, insulation, and fat storage
aerobic - CORRECT ANSWER - steps in the cellular respiration process that require
oxygen
Alpha decay - CORRECT ANSWER - 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 ANSWER - thin walled air sacs which are site of gas exchange
anbolism - CORRECT ANSWER - the process by which cells build molecules and store
energy
anaerobic - CORRECT ANSWER - steps within the cellular respiration process that do not
require oxygen
, anaphase - CORRECT ANSWER - 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 ANSWER - negative ions
Archimedes' principle - CORRECT ANSWER - 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 ANSWER - large blood vessels that carry blood away from the heart
Atmospheric pressure - CORRECT ANSWER - pressure that results in the atmosphere
exerting force on the earth; can be measured with a barometer
atom - CORRECT ANSWER - the simplest unit of an element that reatains the element's
characteristics.
Atomic Mass - CORRECT ANSWER - calculated by adding up the masses of the protons
and neutrons
Atomic number - CORRECT ANSWER - the number of protons found in the nucleus of
an atom of that element
atomic weight - CORRECT ANSWER - the average mass number
B cells - CORRECT ANSWER - class of lymphocyte cells that merge from the bone
marrow mature and produce antibodies, which enter the blood stream
