| 2998208372 | evolution | Process of change that has transformed life on Earth from its earliest beginnings to the diversity of organisms living today. | 0 | |
| 2998208373 | biology | Scientific study of life. | 1 | |
| 2998208374 | emergent properties | Due to the arrangement and interactions of parts as complexity increases. | 2 | |
| 2998208375 | systems biology | An approach that attempts to model the dynamic behavior of whole biological systems based on the study of the interactions among the system's parts. | 3 | |
| 2998208376 | levels of biological organization | Biosphere Ecosystems Communities Populations Organisms Organs and Organ Systems Tissues Cells Organelles Molecules | 4 | |
| 2998208377 | eukaryotic cell | Subdivided by internal membranes into various membrane-enclosed organelles. | 5 | |
| 2998208378 | prokaryotic cell | DNA not separated from the rest of the cell by enclosure in a membrane-bounded nucleus. | 6 | |
| 2998208379 | DNA (deoxyribonucleic acid) | All of a cell's genetic material. | 7 | |
| 2998208380 | genes | The units of inheritance that transfer information from parent to offspring | 8 | |
| 2998208381 | gene expression | Process by which the information in a gene directs the production of a cellular product. | 9 | |
| 2998208382 | genome | The entire "library" of genetic instructions that an organism inherits. | 10 | |
| 2998208383 | classifying life | - Domain - Kingdom - Phylum - Class - Order - Family - Genus - Species | 11 | |
| 2998208384 | three domains of life | 1. Bacteria 2. Archae 3. Eukarya | 12 | |
| 2998208385 | natural selection | Natural environment "selects" for the propagation of certain traits among naturally occurring variant traits in the population. | 13 | |
| 2998208386 | science | An approach to understanding the world. | 14 | |
| 2998208387 | inquiry | Search for information and explanation | 15 | |
| 2998208388 | data . | Recorded observations | 16 | |
| 2998208389 | Qualitative | recorded descriptions | 17 | |
| 2998208390 | Quantitative | measurements | 18 | |
| 2998208391 | inductive reasoning | Collecting and analyzing observations to lead to important conclusions. | 19 | |
| 2998208392 | hypothesis | Proposed explanation to a set of observations | 20 | |
| 2998208393 | deductive reasoning | After hypothesis is formed; Involves logic that flows in the opposite direction, from general to specific. | 21 | |
| 2998208394 | controlled experiment | One that is designed to compare an experimental group with a control group. | 22 | |
| 2998208395 | theory | 1. Broader than a hypothesis. 2. General enough to spin off new hypotheses 3. Supported by a much greater body of evidence. | 23 | |
| 2998208396 | model organism | Species that is easy to grow in the lab and lends itself well to the questions being investigated. | 24 | |
| 2998208397 | technology | Applies scientific knowledge for some specific purpose. | 25 |
