Definition of Moral. Derived from the Latin term âmorÄlis,â moral means a message conveyed by, or a lesson learned from, a story, a poem, or an event. It is not necessary that the author or the poet has clearly stated it. It can be left for the audiences or the learners to derive. However, at times, moral is clearly stated in the shape of a proverb. The moral to a story is a universal aspect of the majority of fictional literature that it not only entertains, but also it serves the purpose of instruction, information, and improvement of the audiences.

A pilus (Latin for 'hair'; plural: pili) is a hairlike appendage found on the surface of many bacteria. The terms pilus and fimbria (Latin for 'fringe'; plural: fimbriae) can be used interchangeably, although some researchers reserve the term pilus for the appendage required for bacterial conjugation.All pili are primarily composed of oligomeric pilin proteins. Dozens of these structures can exist on the bacteria.ome pili, called type IV pili, generate motile forces. The external ends of the pili adhere to a solid substrate, either the surface to which the bacteria are attached or to other bacteria, and when the pilus contracts, it pulls the bacteria forward, like a grappling hook.
