Literally 'having poles' (like a magnet), but used to describe cells that have one or more axes of symmetry. In epithelial cells, the polarity meant is between apical and basolateral regions; in moving cells, having a distinct front and rear. Some cells seem to show multiple axes of polarity (which will hinder forward movement).
Refers to the electronically lop-sided condition of a molecule that has one half more negative than the other half. A state or condition of having poles or possessing parts or regions of opposite or contrasting effects. Polar (hydrophobic) and apolor (hydrophilic) portions of a molecule may be present on a surfactant or a pesticide.
The concept of equal, opposite energies. The Eastern Yin Yang is a perfect example. Yin is cold; yang is hot. Other examples Goddess/God, night/day, Moon/Sun, birth/death, dark/light, psychic mind/unconscious mind. Universal balance.

1) The condition of being positive or negative with respect to some reference point or object.
2) The direction of flow of electricity either negative to positive or positive to negative. Matching polarity between different amplifiers can greatly reduce hum and the risk of elictrical shock. Most amps come equipped with a 'polarity switch'.

The positive or negative direction of an electrical, acoustical or magnetic force. Two identical signals in opposite polarity are 180 degrees apart at all frequencies. Polarity is not frequency dependent. Found on http://www.diracdelta.co.uk/science/source/p/o/polarity/source.html
When applied to solvents, this rather ill-defined term covers their overall solvation capability (solvation power) for solutes (i.e. in chemical equilibria: reactants and products; in reaction rates: reactants and activated complex; in light absorptions: ions or molecules in the ground and excited state), which in turn depends on the action of all ...Found on http://www.chem.qmul.ac.uk/iupac/gtpoc/PQ.html
