Teacher Resource III: Assessment Short Answer 44. A mysterious disease has struck 15 horses at a farm with 100 horses. Doctors at the animal hospital test the blood of five of the sick horses and find that four of them show a type of bacteria never seen before. a. Based on this information, suggest a reasonable hypothesis for the cause of the disease. b. Suggest one experiment you could do to provide evidence for or against your hypothesis. Extended Response 45. In the 1940s and 1950s, the pesticide DDT was sprayed to kill mosquitoes. It was very effective in reducing mosquito populations. However, by the 1960s, DDT-resistant mosquitoes had begun to appear in greater numbers around the world. How would a scientist describe what happened to the mosquito population and explain how this changed the effectiveness of DDT. 46. Rita began taking a ten-day treatment of antibiotics three days ago. The antibiotics worked quickly, and Rita feels completely better after only three days. Antibiotics upset Rita s stomach, so she wants to stop taking them. Should Rita stop taking the antibiotics or finish the treatment? Explain the advantages and disadvantages of stopping and of continuing the antibiotics. Be sure to include your final recommendation, any trade-offs involved, and your reasons for your decision. TR-260
