3077117213 | Characteristics of Living Organisms | Are organized Acquire materials and energy Reproduce Respond to stimuli Are homeostatic Grow and develop Have the capacity to adapt | 2 | |
3077139772 | A cell is ... | the smallest unit of life. | 3 | |
3077142868 | A tissue is ... | a group of similar cells that perform a particular function. | 4 | |
3077145126 | An organ is ... | several tissues joined together. | 5 | |
3077149287 | An organ system is ... | a group of organs working together . | 6 | |
3077156102 | Homeostasis | "staying the same" it refers to the requirement that organisms maintain a relatively constant internal environment (ie temperature or pH balance | 7 | |
3077162956 | Natural Selection | The differential reproductive success of adapted individual. It results in changes of characteristics of a population over time | 8 | |
3077167753 | Evolution | The change in frequency of traits in populations and species | 9 | |

3077207841 | Community | All the different populations in the same area | 19 | |
3077209073 | Population | All the members of a species within a particular area | 20 | |
3077215472 | Ecosystem characteristic: Chemical cycling | Chemicals move from one species to another | 21 | |
3077216576 | Ecosystem characteristic: Energy flow | Energy flows from the sun, through plants, through the food chain | 22 | |
3077228170 | Biodiversity | Encompasses: ~Total number of species ~The variability in their genes ~The ecosystems in which they live | 23 | |
3076225152 | Scientific Method | Observation, Hypothesis, Experiment/Observation, Conclusion, Scientific Theory | 24 | |
3077238965 | Inductive reasoning | Using creative thinking to combine isolated facts into a cohesive whole. Specific instances inform a general theory. | 25 | |
3077243825 | Deductive reasoning | How scientists test a hypothesis; involves "if, then" logic. The process of reasoning from a general premises to reach a logically certain specific conclusion. | 26 | |
3077267310 | Independent Variable | Factor of the experiment being tested. Also called the Experimental Variable | 27 | |
3077271352 | Dependent Variable | Result or change that occurs due to the experimental variable. Also called the Response Variable | 28 |
