BIO 189 MIDTERM STUDY GUIDE WITH COMPLETE
SOLUTIONS
Animals
Answers A multicelled eukaryotic consumer that is made up of unwalled cells and
develops through a series of stages. Most ingest food, reproduce sexually, and can
move from place to place.
Archaea
Answers Group of prokary-otes that are more closely related to eukaryotes than to
bacteria.
Atom
Answers Smallest unit of matter. Consists of varying numbers of protons,
neutrons, and electrons.
Bacteria
Answers The largest, most diverse and well-known group of prokaryotes
(organisms that lack a nucleus); branched off from the lineage leading to archaea
and eukaryotes early in the history of life.
Biology
Answers The scientific study of life.
Biosphere
Answers All regions of Earth where organisms live.
Cell
,Answers Smallest unit of life. All start out life with a plasma membrane, cytosol,
and DNA.
Community
Answers All populations of all species living in a defined area.
Consumer
Answers Organism that acquires carbon by feeding on the tissues, wastes, or
remains of other organisms; most also acquire energy the same way.
control group
Answers In an experiment, a group of individuals identical to an experimental
group except for the variable under investigation.
critical thinking
Answers The act of evaluating information before accepting it.
Data
Answers Factual information collected from experiments or observations of the
natural world.
development
Answers In multicelled species, the process by which the first cell of a new
individual gives rise to an adult.
Ecosystem
Answers A community interacting with its environment.
, Eukaryotes
Answers Organisms whose cells characteristically have a nucleus
protists, fungi, plants, and animals are examples of
Answers Eukaryotes
experiment
Answers Procedure designed to evaluate a prediction; typically yields data.
experimental group
Answers In an experiment, a group of individuals who have a certain characteristic
or receive a certain treatment. Tested side by side with a control group.
fungi
Answers Single-celled or multicelled eukaryotic consumer that breaks down
material outside itself, then absorbs nutrients released from the breakdown.
genus
Answers A group of species that share a unique set of traits. First part of a species
name.
Growth
Answers Increases in the number, size, and volume of cells.
