using a 100 MWCO membrane means that any element, molecule, ion or particle with a molar mass of less than or equal to 100 will be able to pass through. there is an infinite number of combinations able to pass through. sodium and calcium ions would both pass through for example.
What does diamonds stand for
GPS - Global Positioning System
It is often on a metal stand.
In biochemstry, it stand for 2,3-bisphosphoglycerate
molecular weight cut off
200 MWCO
20 MWCO
200 MWCO
Once diffusion occurs it does not matter the MWCO of the membrane, but it depends on difference of concentration, as it is said in Fick's first law.
None. The molecules were either too polar or they were too big to be transported.
Because Na has MW of ~23 and Cl has MW of ~35...both of which are small enough to pass through a molecular weight cut off (MWCO) of 50 (don't add there molecular weights together). urea has ~ MW of 60 so it's too big to cross membrane.

First of all, the filtration in dialysis doesn't happen in the tubing. Rather it happens in an artificial kidney called the dialyzer. It's essentially a dense bundle of thousands of fibers which make up the filter itself. The fibers allow the blood to pass through the dialyzer and the potassium and bicarbonate solution used to mix with the blood crosses over the fibers, cleaning the blood via filtration. MWCO (molecular weight cut off) in dialysis simply means the amount of molecules that are allowed to pass through the membranes. Proteins are too big to pass by design as we don't want to "wash away" the good stuff. Wastes like urea, nitrogen etc are allowed to pass through and out of the blood before the blood returns to the patient. Generally, the bigger the patient, the more filtration is required, so the higher the MWCO is. Hope this helps!
cuz Albumin has much higher weight other than 200 while Glucose has 180 Da, small enough to pass through the membrane pores
A homophone for stand is "stann," which is a rare alternative spelling of 'stand.'
When the night has come And the land is dark And the moon is the only light we see No I won't be afraid No I won't be afraid Just as long as you stand, stand by me And darling, darling stand by me Oh, now, now, stand by me Stand by me, stand by me If the sky that we look upon Should tumble and fall And the mountain should crumble to the sea I won't cry, I won't cry No I won't shed a tear Just as long as you stand, stand by me And darling, darling stand by me Oh, stand by me Stand by me, stand by me, stand by me Whenever you're in trouble won't you stand by me Oh, now, now, stand by me Oh, stand by me, stand by me, stand by me Darling, darling stand by me Stand by me Oh stand by me, stand by me, stand by me
