| Question | Answer |
|---|---|
| Adaptation | Evolution of a structure, behavior, or internal process that enables an organism to respond to environmental factors and live to produce offspring. |
| Biology | The study of life that seeks to provide an understanding of the natural world. |
| Development | All of the changes that take place during the life of an organism; a characteristic of all living things. |
| Energy | The ability to cause change; organisms use the energy to perform biological functions. |
| Environment | Biotic and abiotic surroundings to which an organism must constantly adjust; includes air, water, weather, temperature, other organisms, and many other factors. |
| Evolution | Gradual change in a species through adaptations over time. |
| Growth | Increase in the amount of living material and formation of new structures in an organism; a characteristic of all living things. |
| Homeostasis | Organism's regulation of its internal environment to maintain conditions suitable for survival; a characteristic of all living things. |
| Organism | Anything that possesses all the characteristics of life; all organisms must have an orderly structure, produce offspring, grow, develop, and adjust to changes in the environment. |
| Organization | Orderly structure of cells in an organism; a characteristic of all living things. |
| Reproduction | Production of offspring by an organism; a characteristic of all living things. |
| Response | An organism's reaction to a change in its internal of external environment. |
| Species | Group of organisms that can interbreed and produce fertile offspring in nature. |
| Stimulus | Anything in an organism's internal or external environment that causes the organism to react. |
| Control | In an experiment; the standard against which results are compared. |
| Data | Information obtained from experiments, sometimes called experimental results. |
| Dependent Variable | In an experiment; the conclusion that results from changes in the independent variable. |
| Experiment | Procedure that tests a hypothesis by collecting information under controlled conditions. |
| Hypothesis | Explanation for a question or a problem that can be formally tested. |
| Independent Variable | In an experiment; the condition that is tested because it affects the outcome of the experiment. |
| Safety Symbol | Symbol that warns you about a danger that may exist from chemicals, electricity, heat, or experimental procedures. |
| Scientific Method | Procedures that biologists and other scientists use to gather information and answer questions; including observing and hypothesizing, experimenting, and gathering and interpreting results. |
| Theory | Explanation of natural phenomenon supported by a large body of scientific evidence obtained from many different investigations and observations. |
| Ethics | The moral principles and values held by humans. |
| Technology | Application of scientific research to society's needs and problems. |
