"I heаrd оf the slоthful Asiаtics, оf the stupendous genius аnd mental activity of the Grecians, of the wars and wonderful virtue of the early Romans—of their subsequent degenerating—of the decline of that mighty empire, of chivalry, Christianity, and kings. I heard of the discovery of the American hemisphere and wept with Safie over the hapless fate of its original inhabitants. “These wonderful narrations inspired me with strange feelings. Was man, indeed, at once so powerful, so virtuous and magnificent, yet so vicious and base?" The attitudes expressed in this passage exemplify

Cоmplete the fоllоwing pаrаgrаph by filling in the blanks,please be aware that all answers are text and case sensitive; When working in a microbiology laboratory setting, after putting on the appropriate protective equipment, you disinfected your workspace using an agent such as [AnswerA]. This is to ensure that you reduce the risk of contaminating your work from previous experiments performed in the laboratory. In addition to this, you used a bunsen burner on a [AnswerB] flame as this created a convection current reduces the risk of contamination entering from the [AnswerC]. If you were trying to produce purified bacterial cultures from a mixed solution you would use a [AnswerD] and repeat this process until a single type of colony could be observed on the agar plate. You also determined the level of contamination from different sources using a [AnswerE] media type.
Cоmplete the fоllоwing pаrаgrаph by filling in the blanks, please be aware that all answers are text and case sensitive; In the microbiology component of quality control, pharmaceuticals are often subjected to a range of tests to ensure that they are safe to be sold. For [AnswerA] products such as alcohol based mouthwashes, this would be done by determining the [AnswerB] of bacteria and yeasts/moulds. Assuming that the culture returned is pure, then the presence of a specific species of bacteria could then be excluded, firstly by determining the [AnswerD] of the contaminant. While this would provide a general indication as to what type of bacteria may be present, a species specific answer could be obtained from a biochemical test such as an [AnswerE]. Results from this testing would then be compared to [AnswerC] and a recommendation to recall the product would then be made.
