This resource begins with a general description of essay writing and moves to a discussion of common essay genres students may encounter across the curriculum. The four genres of essays (description, narration, exposition, and argumentation) are common paper assignments you may encounter in your writing classes.
Antiseptics are mainly used to reduce levels of microorganisms on the skin and mucous membranes. The skin and mucous membranes of the mouth, nose, and vagina are home to a large number of what are usually harmless micro-organisms.
To understand how antiseptic (i.e. antibacterial) soaps work, well first look at how soap functions in general. Most molecules are either water-loving (hydrophilic) or water-hating (hydrophobic). The reason water alone doesnt clean off dirt and germs is because those molecules are mostly hydrophobic.oap is made up of fatty acids (derived from oils or fats) and a base (like sodium hydroxide salt). The soap molecules have hydrophobic (fatty acid chain) and hydrophilic (salt) ends. This combination allows soap molecules to suspend the oils, dirt and germs that are washed away when you soap up.
