| 14751373002 | Biology | the scientific study of life | 1 | |
| 14751375733 | emergent properties | New properties that arise with each step upward in the hierarchy of life, owing to the arrangement and interactions of parts as complexity increases. | 2 | |
| 14751380504 | systems biology | An approach to studying biology that aims to model the dynamic behavior of whole biological systems based on a study of the interactions among the system's parts. | 3 | |
| 14751386512 | Eukaryotic cells | A type of cell that has a membrane-enclosed nucleus and other membrane-enclosed organelles. All organisms except bacteria and archaea are composed of eukaryotic cells. | 4 | |
| 14751391148 | prokaryotic cell | A type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles; found only in the domains Bacteria and Archaea. | 5 | |
| 14751396412 | DNA | A complex molecule containing the genetic information that makes up the chromosomes. | 6 | |
| 14751396413 | Genes | the units of inheritance that transmit information from parents to offspring | 7 | |
| 14751398668 | Genome | All the genetic information in an organism; all of an organism's chromosomes. | 8 | |
| 14751405438 | Bioinformatics | The use of computational tools to store, organize, and analyze huge volumes of data | 9 | |
| 14751410657 | negative feedback | A primary mechanism of homeostasis, whereby a change in a physiological variable that is being monitored triggers a response that counteracts the initial fluctuation. | 10 | |
| 14751415664 | positive feedback | A physiological control mechanism in which a change in some variable triggers mechanisms that amplify the change. | 11 | |
| 14751425543 | Domain Bacteria and Domain Archaea | prokaryotes | 12 | |
| 14751428988 | Domain Eukarya | Domain of all organisms whose cells have nuclei, including protists, plants, fungi, and animals | 13 | |
| 14751431564 | inquiry | The search for information and explanation, often focusing on specific questions. | 14 | |
| 14751433100 | discovery science | describes natural structures and processes as accurately as possible through careful observation and analysis of data | 15 | |
| 14751436219 | inductive reasoning | A type of logic in which generalizations are based on a large number of specific observations. | 16 | |
| 14751437770 | deductive reasoning | A type of logic in which specific results are predicted from a general premise. | 17 | |
| 14751445294 | controlled experiment | An experiment in which an experimental group is compared with a control group that varies only in the factor being tested. | 18 | |
| 14751448912 | Theory | An explanation that is broader in scope than a hypothesis, generates new hypotheses, and is supported by a large body of evidence. | 19 |
