Evolution - Evolution is the process of change that has transformed life on Earth
DNA - Deoxyribonucleic acid: a long linear polymer found in the nucleus of a cell and formed from
nucleotides and shaped like a double helix
Biology - The scientific study of life
Emergent properties - New properties that arise with each step upward in the hierarchy of life, owing to
the arrangement and interactions of parts as complexity increases.
Systems Biology - An approach to studying biology that aims to model the dynamic behavior of whole
biological systems based on a study of the interactions among the system's parts.
Eukaryotic Cell - A type of cell with a membrane-enclosed nucleus and membrane-enclosed organelles.
Organisms with eukaryotic cells (protists, plants, fungi, and animals) are called eukaryotes.
Prokaryotic Cell - A type of cell lacking a membrane-enclosed nucleus and membrane-enclosed
organelles. Organisms with prokaryotic cells (bacteria and archaea) are called prokaryotes.
Gene - A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or
RNA, in some viruses).
Gene expression - The process by which information encoded in DNA directs the synthesis of proteins
or, in some cases, RNAs that are not translated into proteins and instead function as RNAs.

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 creature such as a plant, animal or a single-celled life form, or something that has
interdependent parts and that is being compared to a living creature
Organs - A specialized center of body function composed of several different types of tissues.
Organ Systems - A group of organs that work together in performing vital body functions.
Tissues - An integrated group of cells with a common structure, function, or both.
Organelles - Any of several membrane-enclosed structures with specialized functions, suspended in the
cytosol of eukaryotic cells.
Cell - The part of a neuron that houses the nucleus and most other organelles.
Molecule - Two or more atoms held together by covalent bonds.
Negative Feedback - A form of regulation in which accumulation of an end product of a process slows
the process; in physiology, a primary mechanism of homeostasis, whereby a change in a variable triggers
a response that counteracts the initial change.
