←←←←←← Theory
A mathematical and experimental technique employed in the sciences based on a series of observations.
Inductive Reasoning
A method of drawing conclusions by going from the specific to the general.
Observational
(Less reliable)
Deductive Reasoning
A method of drawing conclusions by going from general to the specific.
If ☛ then
Testable
Data
Information that has been translated into a form that is efficient for movement or processing.
Hypothesis
A testable, controllable and falsifiable explanation for a set of observations based on the available data and guided by inductive reasoning. A hypothesis is narrower in scope than a theory.
Theory
Best explanation for observed phenomenon. A conditional fact that could be proven wrong, but rarely does.
Life
Any system capable of performing functions such as eating, metabolizing, excreting, breathing, moving, growing, reproducing, and responding to external stimuli.
Organization
Has definite shape and structure
Biosphere
The entire portion of Earth inhabited by life; the sum of all the planet’s ecosystems.
Ecosystem
The entire portion of Earth inhabited by life; the sum of all the planet’s ecosystems.
Community
All the organisms that inhabit a particular area; an assemblage of populations of different species living close enough together for potential interaction.
Population
A group of individuals of the same species that live in the same area and interbreed, producing fertile offspring.
Organism
A form of life composed of mutually interdependent parts that maintain various vital processes.
Organ
A grouping of tissues into a distinct structure, as a heart or kidney in animals or a leaf or stamen in plants, that performs a specialized task.
Tissue
Any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.
Cell
The smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.
Organelle
Any of several membrane-enclosed structures with specialized functions, suspended in the cytosol of eukaryotic cells.
Molecule
Two or more atoms held together by covalent bonds
Atom
The smallest unit of matter retains the properties of an element.
Sub-atomic
a particle which is smaller than an atom in size.
Metabolism
The chemical changes that take place in a cell or an organism.
Anabolism
A biochemical process in metabolism where the simple molecules combine or build up to generate complex molecules. Negatively charged, addition of electrons.
Catabolism
All chemical or enzymatic reactions involved in the breakdown of organic or inorganic materials such as proteins, sugars, fatty acids, etc. Positively charged, removal of electrons.
