applied science a form of science that solves real-world problems
atom a basic unit of matter that cannot be broken down by normal chemical reactions
basic science science that seeks to expand knowledge regardless of the short-term application of that knowledge
biology the study of living organisms and their interactions with one another and their environments
biosphere a collection of all ecosystems on Earth
cell the smallest fundamental unit of structure and function in living things
community a set of populations inhabiting a particular area
control a part of an experiment that does not change during the experiment
deductive reasoning a form of logical thinking that uses a general statement to forecast specific results
descriptive science a form of science that aims to observe, explore, and find things out
ecosystem all living things in a particular area together with the abiotic, nonliving parts of that environment
eukaryote an organism with cells that have nuclei and membrane-bound organelles
evolution the process of gradual change in a population that can also lead to new species arising from older species

homeostasis the ability of an organism to maintain constant internal conditions
hypothesis-based science a form of science that begins with a specific explanation that is then tested
hypothesis a suggested explanation for an event, which can be tested

organelle a membrane-bound compartment or sac within a cell
organism an individual living entity
organ a structure formed of tissues operating together to perform a common function
peer-reviewed article a scientific report that is reviewed by a scientist’s colleagues before publication
phylogenetic tree a diagram showing the evolutionary relationships among biological species based on similarities and differences in genetic or physical traits or both
physical science a field of science, such as astronomy, physics, and chemistry, that studies nonliving matter
population all individuals within a species living within a specific area
prokaryote a unicellular organism that lacks a nucleus or any other membrane-bound organelle
science knowledge that covers general truths or the operation of general laws, especially when acquired and tested by the scientific method
scientific law a description, often in the form of a mathematical formula, for the behavior of some aspect of nature under certain specific conditions
