| 1688326077 | Metabolism | A characteristic of all living organisms to process energy that powers other processes. | 10 | |
| 1688326078 | Homeostasis | A characteristic of all living things to maintain stable internal environments to optimize conditions for metabolism and other processes. | 11 | |
| 1688326079 | Growth and Reproduction | A characteristic of all living organisms to have the capacity for growth and reproduction. | 12 | |
| 1688326080 | Heredity | A characteristic of all organisms to pass genetic information across generations from parents to offspring. | 13 | |
| 1688326081 | Atom | Smallest structure that makes up life. | 14 | |
| 1688326082 | Molecule | Two or more atoms joined together. | 15 | |
| 1688326083 | Organelles | Structures within a cell that are organized to perform specific cellular functions. | 16 | |
| 1688326084 | Cells | Smallest structures that can carry out all the processes of life. | 17 | |
| 1688326085 | Biotic | All living components located in a particular area. | 18 | |

| 1688326087 | Species | A population or group of populations whose members have the potential to interbreed in nature and produce viable fertile offspring. | 20 | |
| 1688326088 | DNA (Deoxyribonucleic Acid) | The genetic code of life. | 21 | |
| 1688326089 | Adaptation | A characteristic that improves an organism's ability to survive and reproduce in a particular environment. | 22 | |
| 1688326090 | Evolution | The modification of populations over time. | 23 | |
| 1688326091 | Regulation | A characteristic that regulates an organism's internal and external environment to survive and reproduce. (Homeostasis) | 24 | |
| 1688326092 | what causes regulation | Increases or decreases in stimuli, feedback mechanisms. | 25 | |
| 1688326093 | Negative Feedback | A primary mechanism of homeostasis, whereby a change in a physiological variable triggers a response that counteracts the initial change. | 26 | |
| 1688326094 | Positive Feedback | A physiological control mechanism in which a change in some variable triggers mechanisms that amplify the change. | 27 | |
| 1688326095 | two ways organisms acquire energy | 1. Cellular Respiration 2. Photsynthesis | 28 | |
