Is an abrasion an open or a short? A value for estimation of electrical injury is that you have about 300-500 ohms of resistance in your internal fluids (you are basically a bag of salty water). Most of your resistance comes from the dead cells of your epidermis, often providing hundreds of kiloohms of resistance. However, if the epidermis is broken due to injury (such as a cut, abrasion, or burn), the resistance to current that the skin provides falls...

Why is it generally thought that microbes are less likely to develop resistance to biocides? Group of answer choices these compounds are only rarely used and do not accumulate in the environment biocides are generally non-toxic and so there is no benefit to resistance the biocide affects multiple cellular structures/functions in a susceptible cell microbes can safely degrade most biocides

Brief Background Penetration hardness is a measure of a materials resistance to indentation. The Rockwell Hardness test is a standard method for characterizing this property of a material. It uses a small indenter, either a hardened ball or diamond cone (Brale), which is pressed into the sample while measuring depth of penetration. There are several scales to select from as indicated in textbook or the chart found in lab. Each scale refers to the type of indenter used and the...

Antibiotic resistance occurs when disease-causing microbes become resistant to antibiotic drug therapy. Because this resistance is typically genetic and transferred to the next generation of microbes, it is a very serious public health problem. According to the CDC, 10% of gonorrhea cases tested in 2004 were resistant to the antibiotic ciprofloxacin. A physician prescribed ciprofloxacin for the treatment of 10 cases of gonorrhea during one week of 2004. Find the probability that at most 1 cases was resistant to ciprofloxacin....

Antibiotic resistance occurs when disease-causing microbes become resistant to antibiotic drug therapy. Because this resistance is typically genetic and transferred to the next generation of microbes, it is a very serious public health problem. According to the CDC, 7% of gonorrhea cases tested in 2004 were resistant to the antibiotic ciprofloxacin. A physician prescribed ciprofloxacin for the treatment of 10 cases of gonorrhea during one week in 2004. (c) What is that probability for exactly 2 out of 10?
