independent variables - ANSWER-the variable that is manipulated in an experiment
hypothesis - ANSWER-proposed explanation for an observation
dependent variable - ANSWER-The measurable effect, outcome, or response in which
the research is interested.
control - ANSWER-In an experiment, the standard that is used for comparison
treatment - ANSWER-a specific condition applied to the individuals in an experiment
, prediction - ANSWER-A logical statement about what will happen if the hypothesis is
correct.
experiment - ANSWER-best way to establish casual relationship; manipulates
independent variable and measures dependent variable
non-experimental - ANSWER-not manipulating any variable, only gathers data to test a
hypothesis
descriptive study - ANSWER-not testing a hypothesis, simply making observations
main flaws in experimental designs - ANSWER--no controls
-insufficient sample size
-lack of replication
-not really testing the hypothesis
-important variables not held constant
causation - ANSWER-one event is the result of the occurrence of the other event
Heritable features - ANSWER-those that can be passed down from one generation to
the next
Phylogeny - ANSWER-proposed evolutionary relationship that arise from analyzing
heritable traits among organisms
Systematic analysis - ANSWER-helps create classification systems that convey
information about the evolutionary relationship of organisms
Phylogenetic trees - ANSWER-hypothesize lineage of organisms represented as
branching trees (hypothesis based)
Taxonomy - ANSWER-branch of biology that describes, names, and classifies species
and groups of species
Species - ANSWER-typically defined as a group of organisms in which genetic
exchange through reproduction is possible
The scientific name of an organism is created through - ANSWER-binomial
nomenclature
binomial nomenclature - ANSWER-first word is the genus
second word is the specific epithet
What part of the binomial nomenclature is capitalized? - ANSWER-Genus
Is the binomial nomenclature italicized? - ANSWER-yes
