Emergent Properties- 2 key words - ANS ✔✔Properties emerge at each step along a hierarchy
This results from from the ARRANGEMENT and INTERACTION of parts within a system
AS you go up the organizational ladder, you need to add more in order for it to be more
complex.
** NEW PROPERTY- INTERACTIONS AND ARRANGEMENTS
Reductionism - ANS ✔✔since emergent properties can become complex, we use this method to
reduce complex systems to simpler components that are more manageable to study
e.g. studying molecular structure of DNA helps one be able to understand the basis of
inheritance
