| 9881909113 | plasmolysis | This happens when a cell shrinks inside its cell wall while the cell wall remains intact. |  | 20 |
| 9881909117 | water potential | The physical property predicting the direction in which water will flow, governed by solute concentration and applied pressure. |  | 21 |
| 9881909203 | endothermic | Animals that are warmed mostly by heat generated by metabolism. |  | 22 |
| 9881909208 | homeostasis | "Steady state" or "constant internal milieu". |  | 23 |
| 9881909235 | free energy | Measures the portion of a system's energy that can perform work when temperature and pressure are uniform throughout the system, as in a living cell. |  | 24 |

| 9881909299 | immunization | The deliberate exposure of a pathogen to produce memory cells. |  | 29 |
| 9881909310 | endocrine system | The system of glands that produce endocrine secretions that help to control bodily metabolic activity. |  | 30 |
| 9881909359 | neuron | Structural and functional unit of nervous system. |  | 31 |
| 9881909425 | binary fission | A form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size. |  | 32 |
