In terms of filtration, selectivity is a parameter. It is 1 of 2 factors that determines how successful the membrane filtration process was.
the process of filtration is very important in certain cells of the body . it happens when the fluid forces paticles through filtering membranes its a major part of the kidney function.
Filtration means when a soluble solid (something that doesn't dissolve in water) is separated from liquid HOPE THAT HELPS :)

Potable means water that is safe and fit to drink. Pathogens are disease causing organisms, such as bacteria. Water that contains living pathogens is not potable, That water would need to be treated to kill the pathogens or remove them- chlorination, filtration, etc.
There are several terms for removing solids from a liquid: filtration, settling, decantation or sedimentation.
Filtration is the process of removing one substance or material from another by mechanical means.

are you asking for help on finding definition for geometric terms? if so go to: http://library.thinkquest.org/2647/geometry/glossary.htm#b and to wikipedia for x and j terms
the three terms; point, line and plane can be defined although it is called the undefined terms still we know and we can define the meanings of that terms.. common sense? joke.
