Campbell Biology 12th Edition-Chapter 1
Archaea - ANS One of two prokaryotic domains, the other being Bacteria.
Molecule - ANS two or more atoms held together by covalent bonds
Climate Change - ANS A directional change in temperature, precipitation, or other aspect of the
global climate that lasts for three decades or more.
Biology - ANS the scientific study of life
inquiry - ANS The search for information and explanation, often focusing on specific questions.
Organ - ANS A specialized center of body function composed of several different types of
tissues.
prokaryotic cell - ANS A type of cell lacking a membrane-enclosed nucleus and
membrane-enclosed organelles; found only in the domains Bacteria and Archaea.
Evolution - ANS Descent without modification; the process by which species accumulate
differences from their ancestors as they adapt to different environments over time; also defined
as a change in the genetic composition of a population from generation to generation.
Technology - ANS The application of scientific knowledge for a specific purpose, often involving
industry or commerce but also including uses in basic research.
Population - ANS group of individuals of the same species that live in the same area and
interbreed, producing fertile offspring.
Producer - ANS An organism that produces its own compounds from CO2 by harnessing light
energy (in photosynthesis) or by oxidizing inorganic chemicals (in chemosynthetic reaction
carried out by some prokaryotes).
independent variable - ANS A factor whose value is manipulated or changed during an
experiment to reveal possible effects on another factor (the dependent variable).
DNA (deoxyribonucleic acid) - ANS A nucleic acid molecule, usually a double-stranded helix, in
which each polynucleotide strand consists of nucleotide monomers with a deoxyribose sugar
and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and thymine (T); capable of
being replicated and determining the inherited structure of a cell's proteins.
