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
the study of life
a collection of all ecosystems on Earth
the smallest fundamental unit of structure and function in living things
a set of populations inhabiting a particular area
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 predict specific results
descriptive science
a form of science that aims to observe, explore, and find things out
all living things in a particular area together with the abiotic, nonliving parts of that environment
an organism with cells that have nuclei and membrane-bound organelles
the process of gradual change in a population that can also lead to new species arising from older species
able to be disproven by experimental results
the ability of an organism to maintain constant internal conditions
a suggested explanation for an event, which can be tested
hypothesis-based science
a form of science that begins with a specific explanation that is then tested
inductive reasoning
a form of logical thinking that uses related observations to arrive at a general conclusion
life science
a field of science, such as biology, that studies living things

an individual living entity
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
all individuals within a species living within a specific area
a unicellular organism that lacks a nucleus or any other membrane-bound organelle
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
