Students have asked these similar questions
(a) Describe how a microorganism may become resistant to a drug to which it was
previously susceptible.
(b) What can health care workers do to help prevent the development of drug
resistant microbes?
(c) What can you do on a personal level to help prevent the development of drug
resistant microbes?
2.
The question below is one question I just separated the question marks
1) How are antibiotics, as a class of drugs, unique?
2)How does this facilitate resistance?
3)How are antibiotics misused?
Some antibiotics fail to kill/inhibit a pathogen simply because the microbe is naturally (intrinsically) resistant to it.
True or False ?

Unfortunately, it has not been given the kind of attention it deserves. So a lot of people are unaware of the seriousness of the situation and its consequences. You are expected to do a literature search about this burning issue and turn in a paper. I am not particular about the style you use for the paper. But I am particular about the fact that you must reference every statement you make if you are taking it from somewhere. I want you to use the ACS format to cite your reference Your paper must have an introduction. Your paper must read like an essay (headings are optional). If you use a question answer format I will not grade your paper. Please do not use the numbering or bullet format in writing the paper, the use of paragraphs is more appropriate.
