biospere: the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.
biodiversity: the variety of life in the world or in a particular habitat or ecosystem.
species: a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding
biology: the study of living organisms
organism: an individual animal, plant, or single-celled life form.
cell: the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane
metabolism: the chemical processes that occur within a living organism in order to maintain life.
DNA: deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
system: a set of organs in the body with a common structure or function.
ecosystem: a biological community of interacting organisms and their physical environment.
homeostasis: the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
evolution: the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
adaptation: a change or the process of change by which an organism or species becomes better suited to its environment.
observation: a remark, statement, or comment based on something one has seen, heard, or noticed.
data: facts and statistics collected together for reference or analysis.
hypothesis: a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
experiment: a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
independent variable: a variable whose variation does not depend on that of another.
dependent variable: a variable whose value depends on that of another.
constant: occurring continuously over a period of time.
