| Term | Definition |
|---|---|
| biosphere(1.1) | all organisms and the part of Earth where they exist |
| biodiversity(1.1) | variety of life within an area |
| species(1.1) | group of organisms so similar to one another that they can breed and produce fertile offspring |
| biology(1.1) | scientific study of all forms of life |
| science(1.1) | the knowledge obtained by observing natural events and conditions in order to discover facts and formulate laws or principles that can be verified or tested |
| organism(1.2) | any individual living thing |
| cell(1.2) | basic unit of life |
| metabolism(1.2) | all chemical processes that synthesize or break down materials within an organism |
| DNA(1.2) | molecule that stores genetic information in all organisms |
| system(1.2) | changing, organized group of related parts that interact to form a whole |
| ecosystem(1.2) | collection of organisms and nonliving things, such as climate, soil, water, and rocks, in an area |
| homeostasis(1.2) | regulation and maintenance of constant internal conditions in an organism |
| evolution(1.2) | change in a species over time; process of biological change by which descendants come to differ from their ancestors |
| adaption(1.2) | inherited trait that is selected for over time because it allows organisms to better survive in their environment |
| observation(1.3) | using senses to study the world; using tools to collect measurements; examining previous result searches |
| data(1.3) | observations and measurements recorded during an experiment |
| hypothesis(1.3) | proposed explanation or answer to a scientific question |
| experiment(1.3) | process that tests a hypothesis by collecting information under controlled conditions |
| independent variable(1.3) | condition or factor that is manipulated by a scientist during an experiment |
| dependent variable(1.3) | experimental data collected through observation and measurement |
| constant(1.3) | condition that is controlled so that it does not change during an experiment |
| theory(1.3) | proposed explanation for a wide variety of observations and experimental results |
| measurement(1.4) | a determination of the dimensions of something using a standard unit |
| accuracy(1.4) | a description of how close a measurement is to the true value of the quantity measured |
| precision(1.4) | the exactness of a measurement |
| microscope(1.4) | tool that provides an enlarged image of an object |
| gene(1.4) | a specific region of DNA that codes for a particular protein |
| molecular genetics(1.4) | study of DNA structure and function on the molecular level |
| genomics(1.4) | study and comparison of genomes within a single species or among different species |
| biotechnology(1.5) | use and application of living things and biological processes |
| transgenic(1.5) | organisms whose genome has been altered to contain one or more genes from another organism or species |
