What is function of mucous membrane?</h3>
- Another general defense against possible infections is provided by the mucous membranes that line the digestive, urinary, and respiratory tracts, as well as the nose, mouth, and lungs.
- In order to cover and protect the more delicate cell layers underneath it and to trap waste and particle matter, including microorganisms, mucous membranes are made up of a layer of epithelial cells connected by tight junctions.
- Because they feature ciliated appendages, which resemble hairs, the epithelial cells lining the upper portions of the respiratory tract are known as ciliated epithelial cells.
- Mucus that contains debris is forced out and away from the lungs by the cilia's movement. The mucus is then coughed up, sneezed out, or swallowed and destroyed in the stomach. The mucociliary escalator is another name for this route of elimination.

Answer:
The correct answer will be- the color change will be observed and the solution will turn purplish-black.
Explanation:
Iodine test is performed to test the presence of the carbohydrates mainly starch.
The iodine solution is chemically called potassium iodide which forms a yellow solution. The potassium iodide solution forms a complex with a starch solution which appears a purplish-black color which shows the presence of the carbohydrates.
In the given question, if we add the iodine solution to the beaker after a certain point of time then it will still form a complex with the starch and thus beaker solution will appear darker in color.
