What does a porous rock mean?
porous rocks are rocks through which water etc. can seep or pass through.
What structure is this statement most likely referring to?
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.

State one reason why some molecules can pass through a certain membranebut other molecules can not?
Molecules pass through pores in membranes. If a molecule is larger than the pores or it sticks to other molecules of its kind to form a thick goo, it won't go through.
Which molecules difuse through the lipid portion of the plasma membrane?
Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.
How can a material be porous but also impermeable?
A material can be porous but also impermeable due to its surface structure. The molecular level can allow molecules of air to pass through, but not water molecules.many materials, such as GoreTex, has a surface structure, that at a molecular level can allow molecules of air to pass thru but not molecules of water. This way, you can be protected from falling rain, but also have a material that will "breathe" and wont keep you feeling muggy inside.

Why can't Water pass through solid rock?
It isn't porous
Why can't water pass through solid rocks?
It isn't porous
What is soil and rock that allows water to pass through it called?
permeable rocks
Word describing soil or rock through which water can pass?
The word is porous.
How do you get oxygen to a space station?
They have oxygen generators with catalysts that change the chemical structure of the air molecules that pass through them , converting carbon molecules into oxygen ; that's how the get oxygen to a space station...
What is the meaning of selecting permeable?
Selective permeability refers to the function of plasma membranes that is needed to maintain homeostasis in a cell and prevent foriegn substances from entering through the cells walls. Some molecules can pass, some are blocked
Water cannot pass through solid rock because it is?
The rock is impermeable (not porous).
What is a percolation rate?
It is the rate at which water, or any liquid, can pass through a porous substance
