A team of researchers is running a study looking at the correlation between genetic differences in the enzyme choline acetyltransferase. A deficit in this enzyme, which controls the synthesis of acetylcholine, has been linked to Alzheimer’s disease. The researchers design an algorithm to search the data for similarities. What are the independent and dependent variables employed in this study?

(Choice A)
A
The independent variable is whether that patient has Alzheimer’s disease or not and the dependent variable is amount of genetic variance.

(Choice B)
B
The independent variable is the amount of genetic variance and the dependent variable is whether that patient has Alzheimer’s disease or not.

(Choice C)
C
The independent variable is the amount of deficit in the enzyme choline acetyltransferase and the dependent variable is genetic differences in Alzheimer’s disease.

(Choice D)
D
This study does not contain an independent or a dependent variable.
