Bertram N. Brockhouse - ✔✔1918-2003
-nobel prize in physics in 1994 for neutron spectroscopy
themes connect concept in biology - ✔✔- biology is the study of life and we do not
know the limits of life
- life is continuously changing
- fitting our knowledge into themes helps make sense of biology
5 themes that unify biology - ✔✔1. life is organized
- new properties emerge at each level in the biological hierarchy
- structure and function are correlated in biological organization
- the cell is an organism's basic unit of structure and function
2. life involves the expression and transmission of genetic information
3. life requires energy transfer and transformation
4. organisms interact with other organisms and the physical environment
5. evolution

,evolution - ✔✔- based on the fact that life is connected
-makes sense of everything we know about living organisms
- organisms living on earth are modified descendents of common ancestors
what did Pasteur disprove of - ✔✔the concept of spontaneous generations
theme - ✔✔new properties emerge at each level in the biological hierarchy
hierarchy of life (largest to smallest) - ✔✔- biosphere
- ecosystem
- communities
-populations
-organisms
- organs and organ systems
- tissues
-cells
-organelles
- atoms
the biosphere - ✔✔all the environments on earth that are inhabited by life: includes
most land regions, bodies of water, and the lower atmosphere
ecosystems - ✔✔all living things in a particular area (large) along with nonliving
components with which life interacts (soil, water, air)
communities - ✔✔all organisms that inhabit an ecosystem
population - ✔✔all the individuals of a species living within a specified area

, organisms - ✔✔individual living things are organisms
organs and organ systems - ✔✔an organ is a body part of two or more tissues that
carries out a particular function in an organism
tissue - ✔✔a tissue is an organized group of cells of a particular type
cells - ✔✔a cell is the fundament unit of organisms
organelles - ✔✔organelles are functional, membrane enclosed components that make
up cells present in eukaryotic cells
molecules - ✔✔molecules are composed of atoms
emergent properties - ✔✔each level in a hierarchy has unique properties called
emergent properties
- emergent properties result from the arrangement and interaction of parts within a
system
- emergent properties characterize nonbiological entities as well
- it is difficult to predict emergent properties- source of problems
theme- new properties emerge at each level in the biological example - ✔✔that would
be organ and organ system going all the ways to atoms because they can make
differentness species and life.
structure and function are correlated at all levels of biological organization - ✔✔-
structure and function of living organisms are closely related
theme: structure and function are correlated at all levels of biological organization
example - ✔✔leafs are thin and flat, maximizing the capture of light by chloroplasts
