Answer to Question 1

C
Staining procedures differentiate organisms by using dyes that have been found to stain some bacteria in specific ways. An example of this would be a Gram stain, in which bacteria are first stained with crystal violet, then treated with a strong iodine solution, decolorized with ethanol or ethanol acetone, and then counterstained with contrasting dye. Those retaining the initial stain are considered gram positive; those losing the stain but accepting the counterstain are considered gram negative.

Answer to Question 2

A, B, C, D
Daily exercise and intake of adequate bulk and water are contributions to bowel health. Heeding the need to defecate and defecating at the same time daily will help to keep the gastrocolic reflex healthy. Taking daily laxatives is not conducive to good bowel health.
