24
Biology : the scientific study of life
Evolution : the process of change that has transformed life on Earth
LivingSystems : the most complex chemical systems on Earth
ChemistryandPhysics : life is constrained by the properties of
Homeostasis : maintain internal balance
Sensitivity : respond to their environment
CellTheory : idea that all organisms are composed of cells
PreexistingCells : all cells come from
Cell : the lowest level of organization that can perform all activities required for life
Ribosomes : small proteins that are used to make more proteins
EukaryoticCell : membrane-enclosed organelles
ProkaryoticCell : simple and does not contain a nucleus
Emergent properties : things that you realize once you step back
Ecology : organisms interacting with their environment
ChemicalEnergy : plants take light energy and turn it into
Producers : plants and other photosynthetic organisms
Consumers : use materials made by producers
Energy : work requires
EnergyTransformation : energy exchange between an organism and its environment
Gene : discrete unit of information
Genome : entire set of DNA instructions
ContinuityOfLife : depends on faithful copying of DNA into daughter cells
DNA : controls the development and maintenance of organisms
Taxonomy : branch of biology that names and classifies species into groups
Science : derived from Latin and means “to know”
Inquiry : the search for information and explanation
DiscoveryScience : describes natural structures and processes
ScientificMethod : hypothesis-based science
Hypothesis : a tentative answer to a well-framed question
Theory : a body of interconnected concepts
