Question
Chapter 10, Problem 14bCP
Summary Introduction
To review:
Photochemical reaction in rods, and the process of dark adaptation.
Introduction:
The rods are photoreceptors that contain a purple pigment called rhodopsin. The change in the chemical composition of the rods due to the incident light, initiates a nerve impulse for the vision. The purple color of the pigment rhodopsin is attributed to its transmission of light in the red and blue regions, while absorption in the green region.

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.
