Document Summary
Ltm: activated when info needs to be retained, retrieved into stm when needed, dependent on activity. Themes in biology: (maybe sign up for the class thing: 1 credit) Evolution: unifying idea of biology: all living organisms are modified descendants of common ancestors. Nothing in bio makes sense except in light of evolution- t. Emergent properties: properties result of the arrangement of the parts of the system and how they interact that are absent when separated. Emergence: the whole is more than the sum of its parts.

Levels of biological organizations: biosphere, ecosystems, communities, populations, organisms, organs and organ systems, tissues, cells, organelles, molecules. Hierarchy.

Science is limited to observable and measurable structures and processes.
