Campbell Biology 12th Edition-Chapter 1 Questions with
Answers
Archaea - correct answers One of two prokaryotic domains, the other being Bacteria.
Molecule - correct answers two or more atoms held together by covalent bonds
Climate Change - correct answersA directional change in temperature, precipitation, or other aspect of
the global climate that lasts for three decades or more.
Biology - correct answersthe scientific study of life
inquiry - correct answersThe search for information and explanation, often focusing on specific
questions.
Organ - correct answersA specialized center of body function composed of several different types of
tissues.
prokaryotic cell - correct answersA type of cell lacking a membrane-enclosed nucleus and membrane-
enclosed organelles; found only in the domains Bacteria and Archaea.
Evolution - correct answersDescent 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 - correct answersThe application of scientific knowledge for a specific purpose, often
involving industry or commerce but also including uses in basic research.
Population - correct answersgroup of individuals of the same species that live in the same area and
interbreed, producing fertile offspring.
Producer - correct answersAn 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 - correct answersA factor whose value is manipulated or changed during an
experiment to reveal possible effects on another factor (the dependent variable).
DNA (deoxyribonucleic acid) - correct answersA 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 - correct answersThe entire portion of Earth inhabited by life; the sum of all the planet's
ecosystems.
Bioinformatics - correct answersThe use of computers, software, and mathematical models to process
and integrate biological information from large data sets.
Dependent variable - correct answersA 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).
Genome - correct answersThe genetic material of an organism or virus; the complete complement of an
organism's or virus's genes along with its noncoding nucleic acid sequences.
Model organism - correct answersA 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 - correct answersthe systematic study of whole sets of genes (or other DNA) and their
interactions within a species, as well as genome comparisons between species
tissue - correct answersAn integrated group of cells with a common function, structure, or both.
Experiment - correct answersA 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.
