When looking at the percentage of patients whose symptoms were relieved after taking a placebo, a scientist sees a 20% success rate. The success rate of patients whose symptoms were relieved after taking a new composite drug was 30%. The scientist determines that the margin of error is 10%, which indicates that the new drug had no statistically significant positive effect. In which stage of the engineering process is this scientist?A.Looking for future improvementsB.Evaluating test resultsC.Identifying a needD.ScreeningSUBMITarrow_backPREVIOUS

The process of using computers and robots to conduct thousands of tests to determine the interaction between different compounds and a disease is called what?A.Evaluating test resultsB.The engineering processC.High-throughput screeningD.An intravenous solution

A scientist wants to create a drug that will kill cancer cells upon absorption in the intestines. In order for the drug to work effectively, it must not be absorbed until it reaches the intestines. The scientist tests different acidities of compounds to determine which combination will keep the drug intact until it reaches the intestines. What part of the engineering process is the scientist engaged in?A.TestingB.Making a planC.Determining a needD.Looking for improvements

Which of the following drugs can be taken to cure some communicable diseases?AntibioticsPainkillersAntisepticsDecongestants2Which of the following statements about antibiotics is not true? They have greatly reduced deaths from communicable diseasesThey can kill bacterial pathogensResistant strains of bacteria are emergingThey can kill viral pathogens3The first stage of testing a new drug involves computer modelling followed by testing on cells, tissues and animals. What is this stage known as? Clinical trialPlacebo effectDouble blind trialPre-clinical testing4Potential new drugs are tested extensively before they can be licensed. Which of the following best describes the four criteria that new drugs must meet?Effective, cheap, stable, successfully taken into and removed from the bodyEffective, safe, cheap, successfully taken into and removed from the bodyEffective, safe, stable, successfully taken into and removed from the bodyEffective, toxic, stable, successfully taken into and removed from the body5In clinical trials, the placebo looks identical to the drug being tested, but contains:A lower concentration of the drugNone of the drugA higher concentration of the drugA different drug6In which type of clinical trial do neither the patients nor the doctors know who is receiving the drug and who is receiving the placebo?Double blind trialControl trialBlind trialOpen trial

With the rise of drug-resistant bacteria in hospitals there has been an effort to develop new antibiotics as well as novel methods to combat resistant infections. The sequencing of entire communities of microbes including environmental samples has led to the discovery of millions of uncharacterized bacteria that could provide new drugs. This sequencing method is called ________.Group of answer choicesshotgun genomicsenvironmental genomicsbiomimetic genomicswhole-community sequencing
