Term
Seven Characteristics Of All Living Things
Definition
- Cellular organization (organic)
- Reproduce using DNA
- Respond to stimuli
- Growth and development
- Energy utilization
- Homeostasis; constant internal condition
- Evolve as a population
Term
Cellular Level in hierarchy of living things.
Definition
Atoms, molecules, organelles, cells
Cells are the basic units of life.
Term
Hierarchical Organization of Living Things
Definition
Cellular Level
Organismal Level
Populational Level
Term
Hypothesis
Definition
Possible explanation for an observation
Term
Things that a hypothesis must do
Definition
- Must be tested to determine its validity
- Is often tested in many different ways
- Allows for predictions to be made
- Hypothesis can be changed and refined with new data
Term
Experiments
Definition

- Must be carefully designed to test only one variable at a time
- Consists of a test experiment and a control experiment
Term

Definition
Structure is what it is made out of, while function is what it does. Structure can suggest function
Term
Terms Used To Group Together Living Things
Definition

Cell number (unicellular vs. multicellular)

Mode of nutrition (often ingest, absorb, or photosynthesis)
Term
The Three Domains Of Living Things
Definition
Bacteria - single-celled prokarayote
Archea - single-celled prokarayotes that live in harsh enviroments
