After reading the paragraph below, answer the questions that follow.

The functions of some proteins change depending on whether they are in the light or in the dark they are photoreceptive (PR) proteins. A team of scientists recently determined that PR proteins bind to DNA to regulate gene expression in microbes. Answer the following three questions about this scenario.


Suppose that the team of scientists conducted the following experiment: They mixed the PR proteins with DNA in a test tube and measured the amount of protein that bound to the DNA after 10 minutes under variable amounts of light. What was the independent variable in their experiment?
◦ the amount of PR proteins bound to DNA
◦ the amount of light that they exposed the test tube to
◦ the type of PR proteins used in the experiment
◦ the amount of time the light was exposed to the test tube

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
