The capacity to do work

Acquisition of traits by transmission of DNA from parent to offspring

A type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles. Organisms with prokaryotic cells (bacteria and archaea) are called prokaryotes.

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.

New properties that arise with each step upward in the hierarchy of life, owing to the arrangement and interactions of parts as complexity increases. Each level of biological organization has emergent properties.

The steady-state physiological condition of the body.

The three-domain system

Protists, plantae, Fungi, animalia.

Prokaryotic- Bacteria and Archaea, Eukaryotic- Eukarya

Domain, Kingdom, phylum, class, order, family, genus, species.

A scientific discipline concerned with naming and classifying the diverse forms of life. The branch of biology concerned with naming and classifying the diverse forms of life. Formalized process to cutdown confusion.

Central theme in biologythe ability to evolve is built into organismsorganisms within a species are variable( some are better suited to survival) Variability comes from the inherited genes. More good genes survive and therefore the population changes.

Usually proceeds the process of scientific discovery. ObservationHypothesisExperimentConclusion

An explanation of natural events that is based on a LARGE number of observations and/or experiments.
