What will and won't pass through a visking tube?
Cannot pass through visking tubing: sugar starch lactose sucrose Can pass through visking tubing: Iodine Glucose Maltose
What part of body does the water represent in visking tube?
small intestine
How does a visking tubing differ from a cellmembrane?
Visking tubing contains millions of tiny holes which only let small molecules, like water, diffuse through. Large molecules, such as starch, cannot cross the membrane. We say it is partially permeable (permeable means a substance is able to pass through). This is similar to a cell membrane. Visking tubing can therefore be used as a model of a cell.
Can T8 LED tube light be used with ballast and can ballast be removed and will it work?
A T8 LED tube has to be used with a ballast to bring the correct voltage to the tube for it to operate correctly. Removing the ballast from the circuit will prevent the tube from operating.
How does 4 tube fluorescent work?
A four tube fluorescent luminaire is just 4 separate fluorescent lamp circuits in one fitting. Look up 'how things work' etc to see a fluorescent lamp circuit.
Can glucose pass through visking tube?
fine glucose molecules can pass through the wall of the visking tube.
What is a type of tube that is semi-permeable?
visking tubing
What will and won't pass through a visking tube?
Cannot pass through visking tubing: sugar starch lactose sucrose Can pass through visking tubing: Iodine Glucose Maltose
What part of body does the water represent in visking tube?
small intestine
What is visking tubing?
Visking tubing is a kind of seamless semi permeable tubing, a cellulose tubing, that is made of regenerated cellophane. It is used as an edible casing for sausages or as a membrane in dialysis.
How is a visking tube not like a real small intestine?
it is different because widts of the tube and intestine may vary
What is a detailed explanation of how the visking model is good or bad?
can someone tell me what is good about visking tube and whats bad about it asap because i need to give my homework by tmor and my homework relates 2 that
What part of our bodies acts like a visking tube?
You may be thinking of the blood capillaries. Like visking tubing, their walls are able to let substances diffuse in and out. This is also true of the cell membranes. However both of these are much more permeable than visking tubing. The kidney contains semi-permeable membranes which allow urea to pass through but not other substances such as proteins.
What can you use as alternative to visking tube?
the visking tubing is useless and we need an alternative. can u helpful human beings help please? we are in the middle of a chaotic crisis trying to find the reason for osmosis. please help you kind human beings :) i hate you bye -from the scientists of Mars :
How can you use a visking tube to test the hypothesis that osmosis happens faster at higher temperatures?
Put a sucrose solution into the visking tube and fasten the ends, then place it in water (at different temperatures). The varying temperatures would quicken or slow the rate of diffusion (osmosis). Then using iodine, you put some in the water that the visking tube was in and if it turns dark blue/black the more sucrose has diffused. This can be put into a calorimeter to check the intensity for different temps. You should find that the higher the temp. the higher the rate of diffusion (because particles are excited and have more kinetic energy and move more). Hope this helps =) Sana (17 yrs)
Where to find visking tube?
Visking tubing is made of cellulose and often used as a model gut in class room experiments.
Can salt pass through visking tubing?
yes it can
