Expert Solution & Answer

Explanation of Solution

Proper care should be taken while preparing a smear for microscopic examination. The advantages of preparing thin smears are as follows:

1. Thin smears permit easy passage of light, which gives better resolution of bacteria, particularly when using oil immersion.

2. Dense or thick smears will lead to uneven spread of bacteria in the microscopic slide.

3. In the case of dense smears, stains are unable to penetrate the bacterial cell wall.

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?
