Hydrochloric acid is secreted by the glands present on the stomach walls. It dissolves bits of food and creates an acidic medium. The acidic medium allows pepsinogen to be converted into pepsin. Pepsin plays an important role in the digestion of proteins. Therefore, if HCl were not secreted in the stomach, then pepsin would not be activated. This would affect protein digestion. A pH of about 1.8 is necessary for proteins to be digested. This pH is achieved by HCl.

- Supply refers to the quantity of a commodity that a firm is willing and able to offer for sale, at each possible price during a given period of time.

Variable costs vary directly with output – when output is zero, variable costs will be zero but as production increases, total variable costs will rise.
Examples of variable costs include the costs of raw materials and components, packaging and distribution costs, the wages of part-time staff or employees paid by the hour, the costs of electricity and gas and the depreciation of capital inputs due to wear and tear.

The King of Melon City has been defined as ‘just’. We know what kind of justice he used to administer. He was ready to hang anyone who could be blamed for the mishap. He was whimsical and easily influenced. His exaggerated sense of justice caused even his own death. He is called ‘placid’ but loses his temper over a small incident. Actually, the king was too good to be of any use.
