Term | Definition |
Biology | The study of all living things |
Cell | The smallest structured functional unit of life in an organism |
Reproduction | All organisms produce new organisms like themselves and transmit hereditary information to offspring (DNA) can be sexual or asexual |
Genetic code | The information encoded within the genetic material that can be translated into a protein |
Metabolism | The sum of all chemical reactions that take in and transform energy from the environment. |
Grow and develop | Growth- The division and enlargement of cells Development- involves cell differences/ specialization |
Stumuli | A physical or chemical in the internal or external environment. |
Homeostasis | The maintenance of stable internal conditions in a constantly changing environment. |
Evolution | Populations of living organisms may evolve through time individuals may change but genetics don't. |
Controlled experiment | An experiment in which only one variable is manipulated at a time. |
Independent variable | the cause/treatment for the experiment |
Dependent variable | The measurement conclusion or effect |
Control group | test group that doesn't get treatment |
Hypothesis | Never a question, an if then statement that has no personal pronouns and is based on research |
Variables | Something in an experiment that can change |
Data | The information that you can collect in an experiment |
Constant | Something that stays the same in an experiment |
Observation | Qualitative or quantitative information that you record in an experiement |
Natural selection | Organisms have certain favorable traits that allow them to survive and reproduce more than organisms that lack those traits |
Prediction | Something that you expect to happen during an experiement |
Steps of the scientific method | 1. Observation 2. Ask a question/identify a problem... 3. Hypothesis- "if.. then..." never a question and based on research- education guess 4. Experiment 5. Communicate information |
Why is communication important in science | To communicate ideas so that more research can be done. |
Characteristics of life | 1. Cell organization 2. DNA 3. Response to Stimulus 4. Homeostasis 5. Metabolism 6. Growth and Development 7. Reproduction 8. Evolution |
example of organization | Cells organize into organ systems |
example of DNA | A mother has blue eyes and her daughter has blue eyes |
Example of stimuli | A change of light makes the light dilate |
Example of homeostasis | Shivering when the body gets cold |
Example of metabolism | Getting energy from food |
Example of growth | Growing from baby to toddler |
example of evolution | Blue eyes |
Order of organization | Biosphere->Ecosystem->Community->Population->Organism->Groups of Cells->Cells->Molecules |
3 themes of biology | Diversity and Unity of Life Interdependence of Organisms Evolution of Life |
interdependance | All organisms live and interact with each other and their environment. Life can be studied at a variety of different levels |
Diversity of life | Life is diverse yet we are are more similar than we are different Genetic information, biological molecules, structure/organization. All humans are from a single common ancestor |
Evolution of life | Helps us understand how distinct populations and new species come into existence |
