Zechhausen has both the OEM BMW parts and non OEM, performance enhanced parts (since the OEM pads make a lot of brake dust). Edit: Forgot to mention, the way I explained parts should cost you about $200/axle and service about $50-100.You will save at least $500-600.echhausen has both the OEM BMW parts and non OEM, performance enhanced parts (since the OEM pads make a lot of brake dust).

Ethanol can also diffuse through the core of the lipid bilayer, this is because it is also slightly lipophilic (lipid loving) and relatively small. Other kinds of polar compounds are charged, which prevents them from diffusing through the hydrophobic core of the membrane (they can only dissolve in water).thanol can also diffuse through the core of the lipid bilayer, this is because it is also slightly lipophilic (lipid loving) and relatively small.

Yes, true. Passive diffusion does not require energy use. Facilitated diffusion does, because this transportation uses certain proteins as carriers to move the large unsoluble lipid molecules across the membrane in favor of the gradient; from higher concentration to lower concentration; yet energy is used to 'maintain' these proteins.
