Abiogenesis - ansa hypothetical organic phenomenon by which living organisms are
created from nonliving matter
Acid - ansany of various water-soluble compounds having a sour taste and capable of
turning litmus red and reacting with a base to form a salt
Activation Energy - ansthe energy that an atomic system must acquire before a
process (such as an emission or reaction) can occur
Active Site - ansThe specific portion of an enzyme that attaches to the substrate by
means of weak chemical bonds.
Active Transport - anstransport of a substance (as a protein or drug) across a cell
membrane against the concentration gradient
Adoption - ansa legal proceeding that creates a parent-child relation between
persons not related by blood
Aerobic - ansprocess that requires oxygen
Amino Acid - ansmonomer that makes up proteins; contains carboxyl and amino

, Aristotle - ansGreek philosopher. A pupil of Plato, the tutor of Alexander the Great,
and the author of works on logic, metaphysics, ethics, natural sciences, politics, and

follows empirical observation and logic, based on the syllogism, is the essential
method of rational inquiry.

natural variation among different organisms
Atom - ans(physics and chemistry) the smallest component of an element having the
chemical properties of the element

work

of an individual
Autotroph - ansorganism that can capture energy from sunlight or chemicals and use
it to produce its own food from inorganic compounds; also called a producer
Base - ansany of various water-soluble compounds capable of turning litmus blue and
reacting with an acid to form a salt and water
Biogenesis - ansthe production of living organisms from other living organisms
