The kidneys act like a visking tubing in our body. They filter blood and selectively reabsorb substances to maintain the body's balance of electrolytes and fluid volume. This process helps remove waste products from the blood while retaining important nutrients.
No, salt molecules are too large to pass through the pores of Visking tubing, which is a semi-permeable membrane. Only smaller molecules like water can pass through the tubing via osmosis.
The Cajal body acts like the nucleolus in that it is involved in the processing and modification of ribosomal RNA. Like the nucleolus, the Cajal body is also found in the nucleus of the cell and plays a role in ribosome biogenesis.
Yes, the human body can conduct electricity to some extent, but it also acts as a resistor. The conductivity depends on factors like moisture and the presence of minerals in the body. However, it is not recommended to use the body as a conductor as it can be dangerous and lead to electric shock.
Tensile force tends to pull a body apart by stretching or elongating it. This force acts in the opposite direction to compressive force, which tends to push a body together. Tensile force is commonly experienced in materials like ropes, cables, and springs.
The force of gravity pulls you down when you are in water, just like when you are on land. The buoyant force from the water also acts on your body, helping to keep you afloat.
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.
No, salt molecules are too large to pass through the pores of Visking tubing, which is a semi-permeable membrane. Only smaller molecules like water can pass through the tubing via osmosis.
Starch must be broken down into smaller molecules like glucose before it can enter the Visking tubing, as the tubing only allows smaller molecules to pass through its semi-permeable membrane. This breakdown of starch into glucose is typically achieved through the process of digestion, either by enzymes in the body or by external sources such as amylase. Once the starch is broken down into smaller molecules, it can pass through the Visking tubing via osmosis or diffusion.
Because it has starch in it.
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 :
Oh, dude, it's like asking how a hot dog differs from a sausage. A visking tubing is a semi-permeable membrane used for dialysis, while a cell membrane is the outer layer of a cell that controls what goes in and out. So, yeah, one's for filtering fluids, and the other's for holding a cell together. Cool, huh?
We supply Visking tubing and offer the following information: The molecular weight cut-off of this product is 12000 - 14000 daltons. This means in theory that molecules larger in MW than this will not pass through the membranes and ones smaller will. Starch has a very high molecular weight and the tubing is often used to illustrate the effect of enzymes breaking starch down into to simple sugars. Starch therefore should not pass through the membrane wall. The user of this product should be aware that this is a nominal cut-off and long thin molecules above the 14kd cut-off may go through and globular molecules below may be retained. In addition the charge on a molecule may effect the rate of transfer across the membrane.
Yes, it is a partially permeable membrane. It allows certain substances like glucose and water molecules to diffuse through but not large molecules like starch and sucrose. Selectively permeable.
Visking tubes can typically be found at scientific supply companies, online retailers that specialize in laboratory equipment, or possibly at a university or research institution that uses them for experiments.
Mitochondria
The cell membrane acts like the skin on your body because it coats the outside of the cell and protects the organelles.
it is different because widts of the tube and intestine may vary
