Permeability
If I am trying to build a soundproof room, I would use foam and egg cartons for materials.
A young river is very active. It is still at the upper course. It moves at a characteristic high speed that enhances its active down-cutting and under-cutting. Its competence is very high due to its speed. An old river on the other hand is characterised by its materials and also the topography of its course. The old river has lost its competence due to the gradient of its course. The speed is low compared to a young river.
A cell wall on both the plant & animal cells. a cell membrane (yes membrane is spelled M-E-M-B-R-A-N-E.) in just a plant cell. the following contribution is by Draycos a SEMIPERMEABLE membrane will allow some substances to pass and prevent other substances from passing. another name for this kind of membrane is SELECTIVELY PERMEABLE
It is theorized this is a byproduct of the accretion of materials near a black hole residing in the center of the quasar.

Permeability
permeability
permeability
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
permeability
permeability
it allows some but not all materials to cross
endoplasmicrethiculum
permeability
this means that it allows some materials, but not all, to cross it, or permeate it.
The characteristic that a plasma membrane bears is the semi-permeability. This is what keeps certain materials in while keeping certain materials out.
