Over the course of ten years, a rare disorder increases in prevalence such that it eventually affects more than 200,000 people in the United States. Based on the passage and this scenario, which prediction is most consistent with the sociological paradigm of symbolic interactionism?
A) As the number of affected individuals increases, government research funding increases.
B) Affected individuals are less likely to conceal their condition as it becomes less stigmatized.
C) As more people with the condition are treated, it receives less attention as a health concern.

A cell is placed in a medium containing radioactively labeled thymidine. After the cells undergo replication three times, what percentage of the cells will have both strands of DNA labeled?
What is C?
C is correct. This question asks you to determine the percentage of cells with both strands of DNA labeled after three replications of one cell in radioactive thymidine. After three rounds of replication, there will be eight cells: 2 3=8. After the first round, each cell will have one labeled strand and one not labeled. After the second round, two cells will have one labeled and one unlabeled strand, and two cells will have both strands labeled. After the third round, six cells will have both strands labeled. No matter how many rounds of replication occur, there will always only remain two cells that contain one labeled DNA strand and one unlabeled DNA strand.
