Emergent Properties
|
The living world has a hierarchical organization, from molecules to the biosphere. With each step upward in organizational level, novel properties emerge as a result of interactions among components at the lower levels.
|
|
|
The cell
|
Cells are organism's basic unit of structure and function. Prokaryotic (bacteria and archaea), Eukaryotic (protists, plants, fungi, and animals)
|
|
|
Heritable Information
|
The continuity of life depends on the inheritance of biological information in the form of DNA molecules. This genetic information is encoded in the nucleotide sequences of the DNA.
|
|
|
Structure/Function
|
Form and functions are correlated at all levels of biological organization
|
|
|
Interaction with the Environment
|
Organisms are open systems that exchange materials and energy with their surroundings. An organisms environment includes other organisms as well as nonliving factors
|
|
|
Regulation
|
Feedback mechanisms regulate biological systems. In some cases, the regulation maintains homeostasis, a relatively steady state for internal factors such as body temperature
|
|
|
Unity and Diversity
|
Biologists group the diversity of life into three domains; Bacteria, Archaea, and Eukarya. Universal genetic code is same throughout (unity).
|
|
|
Evolution
|
Biology's core theme, explains unity and diversity. Darwinian theory explains adaptation of populations to their environment through differential reproductive success of varying individuals.
|
|
|
Scientific Inquiry
|
Hypothetic-deductive method; depends on repeatability; observations, question, hypothesis, prediction, test.
|
|
|
Science, technology, society
|
Technology is crucial to biology advancement
