Exam 3, Question Set 4 1. Scientists know for certain the origin and evolutionary history of modern humans and other hominids. a. True b. False 2. Which is an accurate statement on the develop of drug resistance in pathogens? a. Bacteria choose to adapt traits and behaviors that allow them to evade antibiotic drugs. b. Cells in the human body acclimate to the drugs, minimizing their effectiveness at combating pathogens. c. Bacteria with sets of genes that allow them to survive exposure to drugs, reproduce and spread those resisting genes more rapidly than those without them. d. None of the above are accurate statements. 3. The flu virus is responsible for many epidemics across the world. Which of the following is NOT an accurate statement about the flu? a. The structure of the flu virus is very simple. b. The flu evolves very rapidly over time. c. Portions of the hemagglutinin on the virus are recognized by human antibodies. d. Evolution of the flu virus is so unpredictable it is not possible to make effective flu vaccines. 4. Pathogens like HIV, Plasmodium , and the flu can be transmitted from one species to another. a. True b. False 5. The dhfr gene in Plasmodium (cause of malaria) is rapidly adapting to the use of Sulfadoxine-Pyrimethamine and Chloroquine. Which of the following is expected to happen to neutral genetic diversity in the bacterial genome around this gene? a. Increased levels of polymorphism due to the action of positive selection favoring a specific variant b. Decreased levels of polymorphism due to the action of positive selection favoring a specific variant c. Natural selection does not act on neutral variation; therefore, it will not be affected. d. None of the above

6. A study was conducted to determine if a new disease transmitted by direct contact is more virulent than a vector-borne disease. What would you expect NOT to be the outcome of this study? a. The directly transmitted disease will be more virulent due to the mobility of its carriers. b. The vector borne disease will be more virulent due to the mobility of its carriers. c. The vector born disease is more virulent due to its ability to spread regardless of status of the carrier. d. All of the statements provide possible outcomes of this study. 7. The tree to below is based on recent evolutionary research. In this tree, which species most likely shares a recent common ancestor with humans? a. Monkey b. Mouse c. Chimpanzee d. Gorilla
