Question | Answer |
---|---|
Biology | Study of living things. |
Aboitic | Nonliving factors in the environment. |
Levels of classification of life (smallest to largest) | Cells-> Tissues -> Organ Systems -> Population -> Community -> Ecosystem -> Biosphere |
Scientific Method | 1. Problem 2. Hypothesis -- educated guess 3. Experiment-- test of a hypothesis 4. Data Analysis 5. Conclusion |
Independent Variable | What "I'' (the experiment) can change; the cause (what is being tested) |
Dependent Variable | The result. |
Constant | Stays the same throughout the experiment. |
Control | Standard of comparison. |
"Balance" between internal and external enviorment. | homestasis |
Data | Information gathered from an experiment. |
Element | Substance that cannot be broken down and is made up of only one item. |
Atom | Smallest unit of an element (matter) |
Bond | An attraction between two atoms that allow the formation of a chemical substance. |
Ionic Bond | Transferring of electrons |
