The correct answer is: by analyzing her average test scores after nights with different amounts of sleep.
This is the best way to approve her hypothesis, because she can compare the results of the tests influenced by different amounts of sleep.
The independent variable (the one that is changed by the scientist) in this hypothesis would be hours of sleep. The dependent variable (the one that is observed and that responds to the change made by the independent variable) would be result of test.

<h2>Intestinal Epithelial Cells (IEC)</h2>
Explanation:
- <em>Polarized intestinal epithelial cells (IEC),</em> as well as the resident microflora, provide a barrier that guards <em>against microbial invasion</em>
- The necessity for the <em>epithelium </em>to maintain an intact barrier between <em>lumen bacteria</em> and the lamina propria is exemplified by the consequences after the barrier function is altered
- Impairment of the barrier function of the <em>intestinal epithelium may be a predominant mechanism in the pathogenesis of inflammatory bowel disease (IBD)</em>
