Bio Chapter 1: Exploring Life

203460450	Biosphere	The entire portion of Earth inhabited by life; the sum of all the planet's ecosystems
203460451	Ecosystem	All the organisms in a given area, along with the nonliving (abiotic) factors with which they interact; a biological community and its physical environment
203460452	Community	An assemblage of all the organisms living together and potentially interacting in a particular area
203460453	Population	A group of interacting individuals belonging to ones species and living in the same geographic area
203460454	Organism	An individual living thing, such as a bacterium, fungus, protist, plant or animal
203460455	Organ System	A group of organs that work together in performing vital body functions
203460456	Organs	A structure consisting of several tissues adapted as a group to perform specific functions
203460457	Tissue	A cooperative unit of many similar cells that perform a specific function with a multicellular organism.
203460458	Cell	A basic unit of living matter separated from it environment by a plasma membrane; the fundamental structural unit of life
203460459	Organelle	A structure with a specialized function within a cell
203460460	Molecule	a group of two or more atoms held together by covalent bonds
203460461	Atom	The smallest unit of matter that retains the properties of an element
203460462	Producer	An organism that makes organic food molecules from carbon dioxide, water, and other inorganic raw materials: a plant, alga, or autotrophic bacterium
203460463	Consumer	An organism that obtains its food by eating plants or by eating animals that have eaten plants
203460464	Decomposer	A consumer that derives its energy from nonliving organic material
203460465	Emergent Properties	New properties that emerge with each step upward in the hierarchy of life, owing to the arrangement and interactions of parts as complexity increases
203460466	System	A more complex organization formed from a combination of components
203460467	Prokaryotic cell	A type of cell lacking a membrane-enclosed nucleus and other membrane-enclosed organelles; found only in the domains Bacteria and Archaea
203460468	Eukaryotic cell	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
203460469	species	a group whose members possess similar anatomical characteristics and have the ability to interbreed.
203460470	Taxonomy	The branch of biology concerned with identifying, naming, and classifying species
203460471	Kingdom	In classification, the broad taxonomic category above phylum or division
203460472	Domain	A taxonomic category above the kingdom level. The three domains of life are Archaea, Bacteria, and Eukarya
203460473	Bacteria	One of two prokaryotic domains of life, the other being Archaea
203460474	Archaea	One of two prokaryotic domains of life, the other being bacteria
203460475	Prokaryote	An organism with prokaryotic cells
203460476	Theory	A widely accepted explanatory idea that is broad in scope and supported by a large body of evidence
203460477	Natural Selection	Differential success in reproduction by different phenotypes resulting from interactions with the environment. Evolution occurs when natural selection produces changes in the relative frequencies of alleles in a population's gene pool
203460478	Evolutionary adaption	a inherited characteristic that enhances an organism's ability to survive and reproduce in a particular environment
203460479	hypothesis	A tentative explanation a scientist proposes for a specific phenomenon that has been observed
203460480	controlled experiment	A component of the process of science whereby a scientist carries out two parallel tests, an experimental test and a control test. The experimental test differs from the control by one factor, the variable
203460481	technology	The practical application of scientific knowledge
