What type of impurities can be removed by filtration? (from water)?
What type of impurities can be removed by filtration? from water pls give explanation and examples ty

Is filtration sufficient to make water suitable for drinking?


Of the three processes involved in the production of urine (filtration, reabsorption, secretion), which one...?
which one is responsible for a positive test for sugar in the urine. Please explain. Thanks Cian, I am not on drugs, nor ever have been. I am asking a simple question that has to do with Biology for my Biology class. I don't see how sugar levels in the urine have anything to do with taking drugs. Maybe you should get a life and a proper education

Example of filtration?


Ochem Lab: Why does methanol have to be ice-cold when used to wash product during filtration?
This is just a general question for most labs requiring filtration. But if you want a specific one Nitration of Methyl Benzoate

What might happen to total glomerular filtration and therefore urine production in a human kidney if all of it?
what might happen to total glomerular filtration and therefore urine production in a human kidney if all of its collecting ducts were totally blocked?a. urine would still be formed as it would simply bypass the collecting ductsb. there would be a high rate of glomerular filtration but no urine producedc. there would be no glomerular filtration but not urine produced

Following filtration how does the nephron return nutrient molecules back to the blood and what may occur if...?
Following filtration how does the nephron return nutrient molecules back to the blood and what may occur if there is an excess of nutrients in the filtrate? Use a specific example to answer the question.

Can colloidal suspensions be separated out by filtration?


A tri-meric protein having a molecular weight of 210 Da in gel filtration.?
A tri meric protein having a molecular weight of 210 Da in gel filtration. The SDS PAGE resolved only two bands of 100 and 60 Da. how would you interpret these data.

What chemical reactions and/or equations occur in filtration?


Water filtration without water tablets?
for school we are making a water filtration device. we can't use purification tablets but we can do anything else. i know soil, grass, rocks, ect will filter it, but that wont get rid of the micro organisms. i think boiling the water is the best way to go about this, but how can i do it? i was going to use a bottle with the sand and stuff in it, and cloth at the bottom to stop any of the solid particles from going through, then a container of some sort to catch the water. i was hoping for a way to boil the water from their, how can i go about this? i don't think the sun will do it, but with a magnifine glass maybe? help please

What is the effect of reducing afferent arteriole radius on filtration rate?


How can you increase the glomerular filtration rate without drugs?
I need to know how to increase the GFR without prescription drugs over the counter are ok, and caffeine etc. is ok. This one has been asked before but it wasn't answered very well In order to assess the intrarenal mechanisms responsible for the natriuretic action of caffeine, the renal clearances of 51 Cr EDTA used as a measure of glomerular filtration rate GFR and lithium used as an index of end proximal fluid delivery were measured in eight healthy males before control period and immediately after experimental period a 400 mg oral dose of caffeine given over 90 min or placebo. GFR was unchanged following either caffeine or placebo.

The Kidney: Filtration and Reabsorption? (no digestive system only excretory system)?
The kidneys play an important role in maintaining homeostasis. They remove waste products from the blood maintain blood pH and regulate the water content of the blood and, therefore, blood volume. That all happens in two processes filtration and reabsorption, but what are they? Can somebody explain for me filtration and reabsorption? Details please
