CAMPBELL BIOLOGY 12TH EDITION-CHAPTER 1
QUESTIONS AND WELL VERIFIED ANSWERS
ACTUAL EXAM!!! 2026
Climate Change - ANSWER -A directional change in temperature, precipitation, or other
aspect of the global climate that lasts for three decades or more.
Biology - ANSWER -the scientific study of life
inquiry - ANSWER -The search for information and explanation, often focusing on
specific questions.
Archaea - ANSWER -One of two prokaryotic domains, the other being Bacteria.
Molecule - ANSWER -two or more atoms held together by covalent bonds
Organ - ANSWER -A specialized center of body function composed of several different
types of tissues.
Model organism - ANSWER -A particular species chosen for research into broad
biological principles because it is representative of a larger group and usually easy to grow in a
lab.
genomics - ANSWER -the systematic study of whole sets of genes (or other DNA) and
their interactions within a species, as well as genome comparisons between species
tissue - ANSWER -An integrated group of cells with a common function, structure, or
both.
Experiment - ANSWER -A scientific test. Often carried out under controlled conditions
that involve manipulating one factor in a system in order to see the effects of changing that
factor.
, prokaryotic cell - ANSWER -A type of cell lacking a membrane-enclosed nucleus and
membrane-enclosed organelles; found only in the domains Bacteria and Archaea.
Evolution - ANSWER -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 - ANSWER -The application of scientific knowledge for a specific purpose,
often involving industry or commerce but also including uses in basic research.
Population - ANSWER -group of individuals of the same species that live in the same
area and interbreed, producing fertile offspring.
Producer - ANSWER -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 - ANSWER -A factor whose value is manipulated or changed
during an experiment to reveal possible effects on another factor (the dependent variable).
DNA (deoxyribonucleic acid) - ANSWER -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.
Biosphere - ANSWER -The entire portion of Earth inhabited by life; the sum of all the
planet's ecosystems.
Bioinformatics - ANSWER -The use of computers, software, and mathematical models to
process and integrate biological information from large data sets.
Dependent variable - ANSWER -A factor whose value is measured during an experiment
or other test to see whether it is influenced by changes in another factor (the independent
variable).
