Chapter 24, Problem 10CTQ
PCBs are human-made pollutants that are not synthesized in nature. However, a remote lake in Alaska was found to contain PCBs even though humans had never set foot near this body of water. Based upon what you have learned in this chapter, develop a hypothesis to explain this finding.

Question 1
Note that it is not appropriate to self-diagnose outside of a medical context and this is a completely hypothetical scenario.
Imagine you have a rash on your foot. You’re concerned that it’s an infection and inoculate a sample onto an agar plate. You wonder, How can I figure out whether the pathogen is a bacterium or a eukaryote?
You decide to use lab supplies to get a basic understanding of the pathogen.
What is one experiment you could do, involving culturing the organism? Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we have done/could do in our lab.
What is a procedure you could do, involving making a slide of the organism? Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we have done/could do in our lab.
Without testing anything, how do you know this is not a viral infection?
Malaria is caused by a microbe that completes part of its sexual life cycle in a mosquito
and part of it's life cycle in a mammal. The mosquito bites the mammal to transmit this
disease. Choose the FALSE statement regarding malaria:
O This would be considered parenteral entry.
O The mosquito would be considered a reservoir.
O This would be considered direct transmission.
O The mosquito would be considered a biological vehicle.
Question 17
Choose the false statement below.
O When bacterial samples taken from the body are grown on nutrient agar medium in the lab, we
see many fewer bacterial species turn up on the agar plates than were in the original sample.
O Normal flora is found on all surfaces of the body exposed to the external environment including
the skin, the covering of the eye, the gastrointestinal tract, the vaginal canal, and the ear canal.
O Normal flora is vastly different on different people but surprisingly not so different between
parts of the body.

- Many types of fruits and vegetables can be fermented into alcoholic beverages. Such was the case recently when prisoners in Utah attempted to make an illegal beverage called “pruno”; however, someone added a weeks-old baked potato to the mix, letting a microbe into the party who was clearly uninvited. Consumers of the pruno began to develop difficulty swallowing, vomiting, double vision, and muscle weakness; three required ventilation therapy. No deaths were attributed to the contaminated beverage. Based on your knowledge of this disease, what form of treatment was used to successfully avoid the worst outcomes of the disease in these patients?arrow_forwardMany types of fruits and vegetables can be fermented into alcoholic beverages.

A) What nervous system disease were the prisoners suffering from, and what was the specific organism involved?arrow_forwardMany of the first prokaryotes to be cultured in a scientific lab were human or animal pathogens. Why would these species be more readily cultured than non-pathogenic prokaryotes? a. Pathogenic prokaryotes are hardier than nonpathogenic prokaryotes. b. Non-pathogenic prokaryotes require more supplements in their growth media. c. Most of the necessary culture conditions could be inferred for pathogenic prokaryotes. d. Pathogenic bacteria can grow as free bacteria, but non-pathogenic bacteria only grow as parts of large colonies.arrow_forward
- You were informed that the oil spill that took place in the Kalba sea reached water desalination plants in the Fujairah area. Formulate a hypothesis to state whether these bacteria will be able to thrive and function properly if they were to be used to treat oil spills in freshwater environments like the Fujairah desalination plants. Support your claim with scientific reasoning explaining why or why not.arrow_forwardSince the seventies, scientists have been manipulating microorganisms to improve humans’ well-being. What are examples of how scientists use microorganisms to improve human life quality.arrow_forwardCan you say that the microbial composition changes over time in each of the body locations? Give two pieces of evidence. Why do you think the scientists also tested the soil around the cadaver? The study was done with mice and their cadavers decomposed on soil graves in the University of Colorado Transgenic Facility. Do you think the graphs would have looked different if the decomposition events would have happened outside during the hot summer months? Explain.arrow_forward

How would you help people understand the enduring value of experimental science to our society for effectively addressing challenging human health problems?arrow_forwardAnthrax-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?arrow_forward
