Answer: The correct answer is Enzymes.
Process of digestion involves the breakdown of large complex molecules ( like carbohydrates, and proteins) present in the food into smaller soluble molecules ( like glucose and amino acids) that can be absorbed by bloodstream and transported to various body organs.
Protein in the stomach is broken down into amino acids with the help of enzyme called as pepsin ( a protease). It is an endo-peptidase that is produced in the stomach and helps in the digestion of proteins at acidic pH of the stomach ( 1.5 to 2).
Answer:the following can be done to allow more NaCl to dissolve;
1.) heating the mixture.
2.) Addition of extra water to the solution.
Explanation:
When sodium chloride is dissolved in water, the polar water molecules are able to work their way in between the individual ions in the lattice. The water molecules surround the negative chloride ions and positive sodium ions and pull them away into the solution. This process is called dissociation. Now when the solution is heated, the rate of the dissociation between the two molecules increases leading to more dissolution of NaCl. Also in the absence of heating, more Water molecules can be added to the solution to decrease it's saturation thereby favouring the dissolution of more NaCl.
