Can viruses adapt by natural selection?
A. No, because there isn't a genetic basis for inheritance between parent and offspring virus particles.
B. No, because there isn't a way to distinguish more fit from less fit virus particles
C. Yes but only via human (domestic/artificial) selection
D. No they evolve by mutations.
E. Yes, virus particles that are most successful successful in reproducing quickly and infecting other host cells are the best adapted.
Which of the following statements is a good, scientific hypothesis
A.
If you eat a turnip every week, it will boost your immune systems.
B.
Consistent intake of raw turnips boosts the human immune system due to the vitamins present in uncooked turnips.
C.
Frozen turnips do not boost your immune system too much.
D.
If you eat a cooked turnip today, it will not boost your immune system
One reason that pathogenic microorganisms have an advantage in the host they infect is because they _______.
a. have previously been encountered through natural exposure
b. have previously been encountered through vaccination
c. strengthen the host’s immune response
d. reproduce and evolve more rapidly than the host can eliminate them
e. reproduce and evolve more slowly than the host can eliminate them.

- A new medication has been found that can stop the spread of a disease significantly by a process that does not allow the virus to leave the infected person's body. Patients who do not take the medication have very high transmission rates. The Center for Disease Control and Prevention (CDC) randomly selected participants for a study and divided them into two groups. The first group received the medication and the second group did not. The CDC has concluded that the medication could halt the spread of the disease. Which statistical study did the CDC most likely use? a They most likely used a sample survey that asked patients who took the medication whether they came in contact with someone who had the disease. b They most likely used an observational study that observed patients, selected at random, to determine whether those patients who took the medication spread the disease to others. c They most likely used an experimental study under controlled circumstances on…arrow_forwardQUESTION 53 Which of the following statements is true? a. Failing to complete a course of antibiotics when being treated with an infection can contribute to antibiotic resistance. b. Chicken pox (direct transmission) likely has higher average virulence than Cholera (water-borne). c. Pathogens typically evolve at the same rate as the host they are infecting. d. Vector-borne pathogens are more likely less virulent than directly transmitted pathogens.arrow_forwardWhy is the Nipah virus a great illustration of a zoonotic disease? A. Because it's carried by fruit bats across Asia but almost never spills over into humans. B. Because it's carried by cats across Asia and easily spills over into humans. C.

Specifically, the first colony contains mice that have been exposed to germs and the second contains mice that are germ-free. Which of the following is a difference you should expect to observe between these colonies of mice? a.Germ-free mice have more motor activity b.Germ-free mice have reduced food intake c.Germ-free mice display less anxiety d.Germ-free mice have more active immune systems Clear my choicearrow_forwardWhich of the following statements accurately describes what we learned about HIV evolution? a. HIV is more deadly in Northern Europe, but more transmissible in Africa. That is why there are more individuals infected with the illness in Africa. b. HIV shares a most recently common ancestor with Simian Immunodeficiency Virus (SIV) such that SIV evolved as it host-switched from chimpanzees and gorillas into humans multiple times. c. Drug development is exceedingly difficult because there are very few drug targets for HIV and AZT (a reverse transcriptase inhibitor) alone is the single most effective treatment for HIV. d. Evolution of HIV virions within a person is quite slow such that a blood draw after 1 year of infection would reveal that every single virion would have the exact same sequence.arrow_forward
- In the 1940s, the U.S. government was looking for a solution to a medical problem: the prevalence of sexually transmitted diseases (STDs) among soldiers. Several now-infamous government-funded studies used human subjects to research common STDs and treatments. In one such study, American researchers intentionally exposed more than 1300 human subjects in Guatemala to syphilis, gonorrhea, and chancroid to determine the ability of penicillin and other antibiotics to combat these diseases. Subjects of the study included Guatemalan soldiers, prisoners, prostitutes, and psychiatric patients—none of whom were informed that they were taking part in the study. 1) What type of Epidemiological Study does this fall under; Descriptive, Analytical, Retrospective, Observational, or Prospective. 2) Please explain why this study was ethical or unethical. 3) We discussed a similar tragic but famous study that happened in the U.S. (it took place in Alabama) in one of our lectures.

- Smallpox is the only disease that has been eradicated from the world. Although we are not yet there for any other disease that affects human beings, some diseases may potentally be eradicated in the future. Which of the following is the least likely to ever be eradicated? a. Cysticercosis b. Polio c. Measles d. Pneumoniaarrow_forwardThree methods have been used to try to eliminate malaria. One is to eliminate the mosquito vectors of the parasite, a second is to kill the parasites after they have entered the human body, and the third is to develop a vaccine against the parasite, allowing the human immune system to provide protection from the disease. Which do you suppose is the most promising in the long run? Why? Think about both the biology of the disease and the efficacy of carrying out each of the methods on a large scale .arrow_forwardThe virus known as H1N1 (swine flu): a. has a high death rate b. has no reliable treatment c. has been harnessed by a vaccine d. occasionally infects people who have direct contact with birds e. is seldom transmitted person-to-personarrow_forward
