Rohan conducted an experiment in which two visking tubes A and B made up of semi-permeable membrane were filled with starch solution and kept in two separate test tubes containing water. These test tubes were then placed in water bath. Fresh saliva was added to visking tube A and boiled saliva was added to visking tube B. What result he would most likely obtain after 10 minutes of conducting experiment?

Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by osmosis—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.[dubious – discuss] The rate of passage depends on the pressure, concentration, and temperature of the molecules or solutes on either side, as well as the permeability of the membrane to each solute. Depending on the membrane and the solute, permeability may depend on solute size, solubility, properties, or chemistry. How the membrane is constructed to be selective in its permeability will determine the rate and the permeability. Many natural and synthetic materials thicker than a membrane are also semipermeable. One example of this is the thin film on the inside of the egg. Note that a semipermeable membrane is not the same as a selectively permeable membrane. Semipermeable membrane describes a membrane that allows some particles to pass through (by size), whereas the selectively permeable membrane will choose what passes through (size is not a factor).
