Question
Chapter 15.3, Problem 10LO
Summary Introduction
To explain: How gene databases are used to gain insights into gene structure, expression, and function.
Concept introduction: Bioinformatics is the study and the analysis of biological data using computational tools. This is accomplished with the help of various software tools used for aligning the sequences in the genome.

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.
