the rate at which velocity is changing. The change may involve an increase or decrease in speed and/or a change in direction. The change my be positive or negative
acceleration
any of two or more alternate forms of a gene that an organism may have for a particular trait
allele
the maximum absolute variation of any periodic function (e.g., a wave)
amplitude
a unit used to measure distances in the solar system equal to the average distance between the sun and earth, approximately 150 million kilometers and abbreviated AU
astronomical unit
an organism that can produce food from inorganic materials (carbon dioxide, sunlight ,water)
autotroph
an asexual reproductive process in which a single cell divides into two cells
binary fission
a system used to name organisms using two words: the genus name and the species name
binomial nomenclature
the temperature at which a liquid changes to a gas. The boiling point of water at sea level is 100 degrees c (212 degrees f)
boiling point
an asexual reproductive process in which an outgrowth of a parent organism detaches and forms a new individual of the same species
budding
characteristics of substances that describe their composition, reactivity, and how the substance changes into different substances
chemical properties
a factor or condition in a scientific experiment that is purposefully kept the same

dominant
a celestial body similar to a planet but orbiting in a zone that has many other object in it (e.g., ceres, pluto)

evidence based on observations or experiments rater than theory
empirical evidence
an organism whose cells contain a nucleus surrounded by a membrane
eukaryote

evolution
the first generation of offspring from the mating of parental organisms (p generation)
F1 generation
a crack in earth’s crust along which movement has occurred
fault
a bend in a layer or several layers of rock
fold
a type of mixture in which different parts can be easily distinguished
heterogeneous
an organism that cannot produce its own food
heterotroph
