The use of the given experiment as a support by the research organization to gain funding. The research proposed by them is the long-term research to develop a continuous pipeline of new drugs and antibiotics. Given: In the given experiment, the researchers use a serial transfer for propagating 1,255 population of Escherichia coli in gradually increasing antibiotic (rifampicin) concentration environment. In the figure B the results of the experiments depicting the percentage of population surviving the antibiotic conditions are shown. Introduction: Antibiotic resistance is the phenomena where the bacteria can evade the attack by antibiotics by acquiring drug resistance plasmids and genes through horizontal or lateral gene transfer. The continuous feeding or the gradual increase in antibiotics provides the bacteria a path to accumulate point mutations, undergo genetic recombination and eventually end up becoming a multidrug resistant (MDR) strain.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
