a foreign protein
aqueduct
a pipe or concrete channel that carries water from a reservoir
artery
a large blood vessel that carries blood away from the heart to parts of the body
asphalt
a black substance that is used for paving roads
atmosphere
the air surrounding a planet
atom
the smallest particle of an element
bacteria
simple one-celled organisms
basal cell skin cancer
a type of slow-growing cancer that often appears on the hands or face as an open sore, reddish patch, mole, or scar
biome
a large region with a certain climate and certain living things
boiling
the rapid change of matter from a liquid to gas
carbon dioxide-oxygen cycle
a process in which plants use carbon dioxide given off by other living things and make oxygen, which is in turn used by the other living things
caterpillar
the wormlike stage in the life cycle of a butterfly or moth
cell membrane
a layer around the cell that controls what can enter or leave the cell
chemical change
a change in the property of matters; a chemical change makes new substances
chemical equation
a statement that shows the rectants and products of a reaction
chemical formula
a group of symbols used to describe a compound(example: H2Ois the chemical formula for water
chemical reaction
a process in which elements or compounds are changed into other substances
chemical symbol
a kind of shorthand that chemists use in which one or two letters stand for an element
cholesterol
a fatlike substances found in all animals
chromosome
a strand of genetic material, or DNA
collid
a mixture of fine particles suspended in another substances, usually a liquid
combustion
the chemical change also known as burning, in which oxygen reacts with fuel to create light and heat
composting
the breaking down of organic material in the soil by aerobic bacteria, fungi, insects, and worms
condensation
the change from a gas to a liquid
conglomerate
a type of sedimentary rock formed from large pebbles and stones
continental polar air mass
a cold, dry air mass; for example, one that forms over Canada and the northern United States
continental shelf
the nearly flat area of the ocean bottom where the ocean meets the continent
continental slope
the sloping area that extends from the edge of the continental shelf to the ocean basin
continental tropical air mass
a warm, dry air mass; for example, one that forms over the southwestern United States
convergence
the independent evolution of similar parts of unrelated organisms as adaptations to the environment(example: wings in bats,birds,and butterflies)
cystoplasm
a jellylike material that makes up most of a cell
density
the quanity of matter in a given unit of volume
diode
an electreonic device that allows current to flow in one direction only
distillation
the process for separating liquid mixtures
DNA
the genetic material found in chromosomes
dominant trait
a trait that can override a recessive trait
echolocation
a system in which sound waves are sent out and their echoes interpreted to determine the direction and distance of objects; certain animals, such as dolphins and bats, use this
electrolysis
the process of using electricity to produce chemical changes; water can be split into hydrogen and oxygen using electrolysis
electron
a particle in atoms that has a negative electrical charge
endothermic reaction
a process in which heat is taken in(example: photosynthesis)
erode
to wear away
evaporation
the slow change of a liquid to a gas
