The people lived in Mesopotamia are known as Mesopotamians.
The physical environment and the natural
resources found in Mesopotamia changed the life of Mesopotamians.
<span>They viewed the world because the environment
is very suitable for agriculture, which freed up time for other activities like
art, religion etc. and thus it makes them the modern society.</span>

Preemptive analgesia, a developing clinical concept, is starting an analgesic regimen before the onset of painful stimuli in order to avoid making the nervous system more sensitive to pain-inducing stimuli in the future.
- Pre-emptive analgesia is an antinociceptive medication administered prior to an incision or surgery, thus it's crucial to keep in mind when it should be administered.
- This aids in avoiding the development of altered afferent input processing, which would otherwise exacerbate postoperative pain.
- The three intravenous opioids that are most frequently used to treat postoperative pain are morphine, hydromorphone (dilaudid), and fentanyl.
- The drug of choice for opiates is morphine, which is frequently utilized.

Answer:
False
Explanation:
The histones that are more positively charged, tight hardly to negatively charged DNA. So, enzymes, such as acetyltransferases, that reduce the positive charge of histones promote transcription.
Chromatin structure and its modifications can change the package of the DNA and consequently, alter the gene expression. The most common modifications of the chromatin are covalent modifications such as acetylation/deacetylation (by acetyltransferases and eacetylases), methylation (by methyltransferases), and phosphorylation (by kinases). This is the way of gene expression regulation.
The effects of modifications are different, for example methylation promotes condensation of the chromatin and as a consequence, prevents binding of transcription factors to the DNA (transcription is repressed).
Acetylation loosens the association between nucleosomes and DNA (because it neutralizes the positive charge of histones) and consequently promotes transcription. Deacetylation is a process opposite to acetylation.
