Biology | the study of life |
4 Characteristics of Life | Organization, Reproduction, Change, Adjust to change |
Levels of Organization | Cells, Tissue, Organ, Organ Systems, Organism |
Energy | the ability to cause change |
Evolution | change over time |
Homeostatsis | the property of a system that regulates its internal environment and tends to maintain a stable, constant condition |
Stimulus | any change either internal or external which leads to a response |
Response | what happens when the organism reacts to the stimulus. |

constants | any factors in the experiment that remain the same regardless if they are in the control or the experimental group. |
experimental group | all conditions are kept the same except for the independent variable being tested |
dependent variable | variable that the experimenter is changing |
independent variable | the result the experimenter is measuring or looking for |
axis the independent variable is graphed on | X-axis |
axis the dependent variable is graphed on | Y-axis |

the vertical axis (up and down) | Y-axis |
qualitative data | data collected that is a description |
quantitative data | data is analyzed by comparing numeric (#)values |
