Question
Chapter 2, Problem 4E.1RQ
Summary Introduction
To explain: The reason why the body tube of the microscope should not be lowered while looking through the ocular lens.
Introduction: Microscope is an optical instrument that is used in visualizing objects that are too small to be seen with the naked eye. Minerals, microbes, plant cell, animal cell, and many more can be magnified and viewed with a microscope.
Expert Solution & Answer
Explanation of Solution
The body tube is present just above the stage of the microscope and attached to its arm. It houses the objective lens and eyepiece lenses that magnify the specimen. The body tube can be lowered or raised with the help of coarse-adjustment as well as fine-adjustment knobs. These knobs are located above or below the microscope’s stage. The body tube must not be lowered while looking through the ocular lens because it might cause the slide to break.

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?
