| 235854592 | evolution | Descent with modification; the change in the genetic composition of a population from generation to generation. [1.1] | |
| 235854593 | biology | The scientific study of life. [1.1] | |
| 235854594 | 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. [1.1] | |

| 235854597 | ecosystem | All living things in a particular area, along with all the nonliving components of the environment with which life interacts. [1.1] | |
| 235854598 | communities | The entire array of organisms inhabiting a particular ecosystem. [1.1] | |
| 235854599 | populations | Consisting of all the individuals of a species living within the bounds of a specified area. [1.1] | |
| 235854600 | organisms | Individual living things. [1.1] | |
| 235854601 | organ systems | Team of organs that cooperate in a specific function, (ex) digestion. [1.1] | |
| 235854602 | organs | These carry out a particular function of the body. [1.1] | |
| 235854603 | tissue | A group of similar cells, usually making up a part of something bigger. [1.1] | |
| 235854604 | cells | Life's fundamental unit of structure and function. [1.1] | |
| 235854605 | organelles | The various functional components that make up cells. [1.1] | |
| 235854606 | molecules | A chemical structure consisting of two or more small chemical units called atoms. [1.1] | |
| 235854607 | systems biology | An approach to studying biology that aims to model the dynamic behavior of whole biological systems. [1.1] | |
| 235854608 | eukaryotic cell | A type of cell with a membrane-enclosed nucleus and membrane enclosed organelles. [1.1] | |
| 235854609 | prokaryotic cell | A type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles. [1.1] | |
| 235854610 | DNA | A double-stranded, helical nucleic acid molecule, consisting of nucleotide monomers with a deoxyribose sugar and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and thymine (T); capable of being replicated and determining the inherited structure of a cell's proteins. [1.1] | |
| 235854611 | genes | A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses). [1.1] | |
| 235854612 | genome | The genetic material of an organism or virus; the complete complement of an organism's or virus's genes along with its noncoding nucleic acid sequences. [1.1] | |
| 235854613 | bioinformatics | The use of computers, software, and mathematical models to process and integrate biological information from large data sets. [1.1] | |
| 235854614 | negative feedback | A primary mechanism of homeostasis, whereby a change in a physiological variable triggers a response that counteracts the initial change. [1.1] | |
| 235854615 | positive feedback | A physiological control mechanism in which a change in a variable triggers mechanisms that amplify the change. [1.1] | |
| 235854616 | domains | (1) A taxonomic category above the kingdom level. [1.2] | |
| 235854617 | bacteria, archaea | The two prokaryotic domains. [1.2] | |
| 235854618 | eukarya | Non prokaryotes belong in this domain. [1.2] | |
| 259507101 | discovery science | The process of scientific inquiry that focuses on describing nature. [1.3] | |
| 259507102 | inquiry | The search for information and explanation, often focused by specific questions. [1.3] | |
| 259507103 | data | Recorded observations. [1.3] | |
| 259507104 | inductive reasoning | A type of logic in which generalizations are based on a large number of specific observations. [1.3] | |
| 259507105 | hypothesis | A tentative answer to a well-framed question, narrower in scope than a theory and subject to testing. [1.3] | |
| 259507106 | deductive reasoning | A type of logic in which specific results are predicted from a general premise. [1.3] | |
| 259507107 | controlled experiment | An experiment in which an experimental group is compared with a control group that varies only in the factor being tested. [1.3] | |
| 259507108 | theory | An explanation that is broad in scope, generates new hypotheses, and is supported by a large body of evidence. [1.3] | |
| 259507109 | model | A representation of a theory of process. [1.3] | |
| 259507110 | technology | The application of scientific knowledge for a specific purpose, often involving industry or commerce but also including uses in basic research. [1.3] |
