Explanation The pH of the blood plasma has to be kept within a narrow limit for the proper functioning of cells. It is done by controlling the excretion of hydrogen ions (H + ) in the urine. The secretion of hydrogen ion into the urine helps in decreasing the pH. If the pH of the filtrate moves down to pH 4.5 it inhibits further secretion. As a result, hydrogen ions that pass into the filtrate are greater than the quantity required to decrease the pH of the unbuffered solution...

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?
