In this way, the distinction between a definition of morality and a moral theory parallels the distinction John Rawls (1971: 9) drew between the general concept of justice and various detailed conceptions of it.
Leaves are the site of the food making process called photosynthesis. In this process, carbon dioxide and water in the presence of chlorophyll (the green pigment) and light energy are changed into glucose (a sugar). This energy rich sugar is the source of food used by most plants.
Browning is the process of becoming brown, especially referring to food. Browning foods may be desirable, as in caramelization, or undesirable, as in an apple turning brown after being cut. Foods, including beverages, can turn brown through either enzymatic or non-enzymatic processes.nzymatic browning is a chemical process, involving polyphenol oxidase, catechol oxidase, and other enzymes that create melanins and benzoquinone from natural phenols, resulting in a brown colour. In general, enzymatic browning requires exposure to oxygen, for example the browning that occurs when an apple is cut.
