Living things are identifiable by:
- movement (even cellular or internal movement)
- growth and development
- response to stimuli
- reproduction
- use of energy
- cellular structure
The rate mainly effects the size of the crystals in the rock forming
The SYMPATHETIC nervous system prepares the body to expend energy whereas the PARASYMPATHETIC nervous system allows the body to restore and conserve energy
The best method for studying both the structure and the function of the brain would be the functional magnetic resonance imaging (fMRI).
This technique measures the blood flow to different brain regions in order to determine which areas are active in certain brain processes. An increase in the blood flow increases the amount the oxygen the area is receiving that is needed for the functioning of the nerve cells.
