Answer:
The nervous system regulates breathing and heartbeats but it's also responsible for regulating the core temperature of the body. So when conditions are too warm or hot and body temperature rises, the blood vessels can dilate causing heat loss. Nerves can trigger sweat glands to release fluid that evaporates and cools the skin so that body temperature begins to lower to a normal condition.

Answer:
No, CREs usually don't account for differences in gene expression levels.
Explanation:
<em>Cis</em>-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene <em>transcription</em>. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate <em>gene expression levels</em>.
Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.
