Use the following information to answer thenext question.Polychlorinated biphenyls (PCBS) aremanufactured chemicals that were used for manyyears in materials such as inks and paints, as wellas coolants for some electrical equipment. Since1977, the manufacture and import of PCBS havebeen banned in Canada, but trace amounts of thesepersistent chemicals are still found in both our foodand our bodies.PCBS are endocrine disruptors that mimic theeffects of estrogen. Exposure to endocrinedisruptors can cause reduced fertility in men bydecreasing the number of Sertoli cells in the testes.Exposure to PCBS has also been linked to thedevelopment of some forms of cancer. Cancercells often have an abnormal number ofchromosomes, which can be shown in a karyotype.1. Explain which stage of mitosis is the best forshowing an abnormal number of chromosomes in acell.

Katelyn had been working for Dr. Johnson for a month, and while she had become quite good at measuring inhibitionzones, she didn’t know why she was doing all this work. She had gotten very curious after she began doing all themeasurements on a new set of antibiotics. # is experiment involved infecting mice with MRSA and tracking how theMRSA grew over time.Data were collected by counting the cells of MRSA taken from $ uid samples from the mice. # e cells were measuredby taking one gram of the $ uid and spreading it over plates, but now Katelyn counted the colonies that grew on theplate after 24 hours. Because there were so many, she actually measured the colonies as “log CFU/g.” A CFU is acolony forming unit, or essentially a cell that will divide into a colony that can be seen. Because there can be so many,Katelyn measured them on a logarithmic (log) scale. # e raw data in her lab notebook looked like the following:Table 1. E% ect of treatment on MRSA in mice after 24 hours of drug…
Choose the false statement: Penicillin is a ß lactam which inhibits bacterial growth by inhibiting DNA polymerase. O Resistance to ß lactamase inhibitors arises when bacteria duplicate the ß lactamase gene. O B lactamase inhibitors are prescribed together with antibiotics like penicillin in order to combat resistance to these antibiotics. Question 10 Choose the false statement below: OUsing multiple antimicrobials in combination is an ineffective strategy because they generally are redundant in effect and the chance of drug resistance will be increased. O Because of its complex structure and multiple binding sites, the ribosome is the target for multiple types of antibiotics. O Choice of an antimicrobial agent may be dependent upon the material treated as well as the susceptíbility of the microbe.
The body uses water as a coolant. However, polychloride biphenyls (i.e., PCBs) are an even more efficient, lipid-soluble coolant. One of the advantages is that PCBs remain fluid over a wide range of temperatures, even above 40o Celsius (or 104o Fahrenheit). They are not a by-product of any part of human metabolism. Why doesn’t the human body use PCBs as coolants?
Because of overuse of antibiotics and/or weakened governmental surveillance of infectious disease, several diseasesthat had been thought to be no longer a threat to humanhealth (e.g., pneumonia and tuberculosis) are rapidly becoming unmanageable. In several instances, so-called superbugs(microorganisms that are resistant to almost all known antibiotics) have been detected. How did this circumstancearise? What will happen if this process continues?
M. tuberculosis (Mtb) takes about 12h to 18h to do a cell division. This partially explains why it takes so long to grow the bacteria for diagnosis (4-6 weeks). How can this impact treatment? Be precise.
In a campus-wide screen for microbes, you find DNA from the bacterial species that causes the bubonic plague, Yersinia pestis. You take the sample back to the lab, and try to grow (very carefully), but can't culture the organism. Provide two possible explanations for why you can't grow this sample in the lab.

Explain the importance of each of the following plasmids: conjugative plasmid, R plasmid, Col plasmid, virulence plasmid, and metabolic plasmid.
During the anthrax crisis of 2001, public health officials urged citizens not to take the antibiotic ciprofloxacin as a preventative measure. Public health officials were concerned that overuse of ciprofloxacin would lead to resistant varieties of anthrax and other bacterial pathogens. Ciprofloxacin is one of the few readily available antibiotics that can treat anthrax. 1)Do you think that public health officials should more directly regulate the availability of ciprofloxacin to ensure its proper use? 2)Why?
Anthrax-laced letters were sent to the Senior Librarian recently. After the building was evacuated and all of the potentially exposed workers had received antibiotics to prevent the establishment of infection, no one was sure how to disinfect the building to make it safe for the return of workers. Your team has been hired by the Management to develop a plan to decontaminate the Building Complex after the arrival of anthrax-laced letters. The Building Complex contains thousands of valuable documents that cannot be destroyed. Workers need to be able to return to the buildings, although they do not need to return immediately. You need to guarantee the safety of workers who return. a. Can you devise an experimental setting to test the effectiveness of your strategy?b. What advice would you give to workers concerned with contaminating their family members?
The world is facing a Corona Virus (COVID-19) Pandemic and as a potential scientist and a microbiology student, you have been required to prepare the easiest and most affordable hand sanitizer that can be utilized by students in various microbiology laboratories. Each student in your class has been given 96% ethanol and you are required to prepare 70% ethanol hand sanitizer in a 2L spray bottle. Describe clearly the method you will use in order to achieve the aim of the practical.
The first step for directly linking a microbe to a specific disease according to Koch's postulates is to O isolate microbes from the blood of healthy animals. obtain a sample of blood or other body fluid from a diseased animal. O culture the blood or other body fluid from a discased animal using nutrient medium. O inject a sample of blood or other body fluid from a diseased animal into a healthy animal. O compare the blood of a sick animal to blood obtained from a healthy animal.
