Layers of cross-bedded sand can be indicative of a DESERT environment wind is responsible for the formation of these sedimentary structures. Sand dunes preserved in rocks can be quite large.

Answer:
In the clinical question Does chronic stress affect inflammatory responses in older men with atherosclerotic disease? There is no comparison, so component C does not exist.
Explanation:
C of Comparison corresponds to the PICO process.
The <u>PICO process</u> is used in the resolution of clinical questions, and serves to enumerate the components that allow the analysis of said question. The acronym for PICO corresponds to:
- <u><em>P</em></u><em>opulation
</em>
- <u><em>I</em></u><em>ntervention</em>
- <u><em>C</em></u><em>omparison
</em>
- <u><em>O</em></u><em>utcome
</em>
In the approach of a clinical question the comparison is established when it comes to appreciating one characteristic with respect to another:
<em>"Do patients with gastritis improve with gastric protectors or only with diet?
"</em>
Here a comparison is established between two therapeutic measures.
In the question "Does chronic stress affect inflammatory responses in older men with atherosclerotic disease?" component C of the PICO process does not exist, because there is no established comparison.
