isotope to decay.
cell that has half the number of
chromosomes as body cells.
measure of how easily a mineral can be
scratched.
waste materials, such as pesticides and
leftover paints, that are harmful to
human health or poisonous to living
organisms.
device that converts thermal energy into
work.
amount of energy required to change a
substance from the solid phase to the
liquid phase.
the amount of energy required for the
liquid at its boiling point to become a
gas.
thermal energy that flows from a warmer
material to a cooler material.
chemical in red blood cells that carries
oxygen from the lungs to body cells, and
carries some carbon dioxide from body
cells back to the lungs.
animal that eats only plants or parts of
plants; mammals with large premolars and
molars for eating only plants.
the passing of traits from parent to
offspring.
animal that produces both sperm and eggs
in the same body.
a mixture which is not mixed evenly and
each component retains its own
properties.
describes an organism with two different
alleles for a trait.
behavioral adaptation for winter survival
in which an animal’s activity is greatly
reduced, its body temperature drops, and
body processes slow down.
regulation of an organism’s internal,
life-maintaining conditions.

each layer in a soil profile—horizon A
(top layer of soil), horizon B (middle
layer), and horizon C (bottom layer).
in humans, chemical produced by the
endocrine system, released directly into
the bloodstream by ductless glands;
affects specific target tissues, and can
speed up or slow down cellular
activities.
living cell in which a virus can actively
multiply or in which a virus can hide
until activated by environmental stimuli.
the result of an unusually hot area at

rock is forced upward and breaks through
the crust.
amount of water vapor held in the air.
dark-colored, decayed organic matter that
supplies nutrients to plants and is found
mainly in topsoil.

genetic information for a trait from each
parent.
compound that has water chemically
attached to its ions and written into its
chemical formula.
saturated or unsaturated compound
containing only carbon and hydrogen
