Bacteria
Scope of variation among living organisms.
Biodiversity
Organism whose cells characteristically have a nucleus.
Eukaryote
Single-celled or multicelled eukaryotic consumer that breaks down material outside itself, then absorbs nutrients released from the breakdown.
Fungus
A multicelled, typically photosynthetic producer.
Plant
Single-celled organism with no nucleus.
Prokaryote
A group of diverse, simple eukaryotes.
Protists
Unique type of organism.
Species
A group of species that share a unique set of traits.
Genus
Group of organisms that share a unique set of traits.
Taxon
Group of individuals identical to an experimental group except for the independent variable under investigation.
Control Group
Evaluating information before accepting it.
Critical thinking
Experimental results
Data
A test designed to support or falsify a prediction
Experiment
In an experiment, a group of individuals who have a certain characteristic or receive a certain treatment.
Experimental group
Testable explanation of a natural phenomenon
Hypothesis
Analogous system used for testing hypothesis
Model
Statement, based on a hypothesis, about a condition that should exist if the hypothesis is correct
Prediction
Systematic study of the observable world
Science
Making, testing, and evaluating hypothesis.
Scientific method
In an experiment, a characteristic or event that differs among individuals or over time.
Variable
Generalization that describes a consistent natural phenomenon for which there is incomplete scientific explanation.
Law of nature
Hypothesis that has not been disproven after many years of rigorous testing.
Scientific Theory
The change that a particular outcome of an event will occur; depends on the total number of outcomes possible.
Probability
Difference between results derived from testing an entire group of events or individuals, and results derived from testing a subset of the group.
