Homework Answers

Answer #1

The basis for the antibiotic resistance is the natural selection of the mutations and the evolutionary stress. The organisms develop resistance to certain specific drugs.

When the mutation in the genes offers resistance to the certain drugs that are used to potentially kill the microorganisms, then these mutated genes are passed between the different members of the microorganism population by reproduction or by plasmid exchange.

The resistant genes can also be produced and selected when the bacteria or other microorganisms is continually put under an evolutionary stress by regular exposure to certain drug. The bacteria that survive the drug pass on the genes that make them resistant to the next generation, untimately generating an entire population resistant to that specific drug.

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, 30% of gonorrhea cases tested in 2004 were resistant to the antibiotic ciprofloxacin. A physician prescribed ciprofloxacin for the treatment of 5 cases of gonorrhea during one week of 2004. Find the probability that at least 3 cases were resistant to ciprofloxacin....

Because this resistance is typically genetic and transferred to the next generation of microbes, it is a very serious public health problem.

Read the following excerpt from the Center for Disease Control about Antibiotic resistance and explain why this is an example of evolution by natural selection similar to the example shown in your textbook in Figure 1.16. What trait is being selected in this case? "“Antibiotic resistance occurs when bacteria develop the ability to defeat the drugs designed to kill them. When bacteria become resistant, antibiotics cannot fight them, and the bacteria multiply. Antibiotic resistance is one of the most...
