| 3665210717 | ecosystem | All the organisms in a given area as well as the abiotic factors with which they interact; one or more communities and the physical environment around them. | 5 | |

| 3665210728 | 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. | 16 | |
| 3665210729 | 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. | 17 | |
| 3665210730 | eukaryotic cell | A type of cell with a membrane-enclosed nucleus and membrane-enclosed organelles and include protists, plants, fungi, and animals. | 18 | |

| 3665210732 | DNA | A nucleic acid molecule, usually a double-helix, in which each polynucleotide strand consists 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. | 20 | |
| 3665210733 | replication | The process of copying DNA before a cell divides. | 21 | |
| 3665210734 | gene | A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses). | 22 | |
| 3665210735 | gene expression | The process by which information encoded in DNA directs the synthesis of proteins or, in some cases, RNAs that are not translated into proteins and instead function as RNAs. | 23 | |
| 3665210736 | 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. | 24 | |
| 3665210737 | genomics | The study of whole sets of genes and their interactions within a species, as well as genome comparisons between species. | 25 | |
| 3665210738 | bioinformatics | The use of computers, software, and mathematical models to process and integrate biological information from large data sets. | 26 | |

| 3665210748 | inductive reasoning | A type of logic in which generalizations are based on a large number of specific observations. | 36 | |
| 3665210749 | hypothesis | A testable explanation for a set of observations based on the available data and guided by inductive reasoning. Narrower in scope than theory. | 37 | |
