Campbell Biology 12th Edition-Chapter 1
1. Archaea: One of two prokaryotic domains, the other being Bacteria.
2. Molecule: two or more atoms held together by covalent bonds
3. Climate Change: A directional change in temperature, precipitation, or other
aspect of the global climate that lasts for three decades or more.
4. Biology: the scientific study of life
5. inquiry: The search for information and explanation, often focusing on specific
questions.
6. Organ: A specialized center of body function composed of several different
types of tissues.
7. prokaryotic cell: A type of cell lacking a membrane-enclosed nucleus and
membrane-enclosed organelles; found only in the domains Bacteria and
Archaea.
8. Evolution: 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.
9. Technology: The application of scientific knowledge for a specific purpose,
often involving industry or commerce but also including uses in basic research.
10. Population: group of individuals of the same species that live in the same
area and interbreed, producing fertile offspring.
11. Producer: 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).
12. independent variable: A factor whose value is manipulated or changed
during an experiment to reveal possible effects on another factor (the
dependent variable).
13. DNA (deoxyribonucleic acid): 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.
14. Biosphere: The entire portion of Earth inhabited by life; the sum of all the
planet's ecosystems.
15. Bioinformatics: The use of computers, software, and mathematical models
to process and integrate biological information from large data sets.
