| Describes an organism that consists of a single cell | 3. Unicellular |
| Describes a tissue, organ, or organism that is made of many cells | 4. Multicellular |
| One of the small bodies that are found in the cytoplasm if a cell that are specialized to preform a specific function. | 5. Organelle |
| Chemical compound that provides physical structure and brings about movement, energy use, and other cellular functions. | 6. Biological molecule |
| The steady-state physiological condition of the body. | 7. Homeostasis |
| The sum of all chemical processes that occur in an organism | 8. Metabolism |
| The gene-directed process by which an organism matures | 9. Development |
| The process of producing offspring | 10. Reproduction |
| The series of steps followed to solve problems, including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions | 11. Scientific Method |
| The process of obtaining information by using the senses | 12. Observation |
| In science, an idea or explanation that is based on observations and that can be tested | 13. Hypothesis |
| A statement mad in advance that expresses the results that will be obtained form testing a hypothesis if the hypothesis is supported; the expected outcome if a hypothesis is accurate | 14. Prediction |
| A procedure that is carried out under controlled conditions to discover, demonstrate, or test a fact, theory, or general truth | 15. Experiment |
