A client with newly diagnosed multiple myeloma asks, "how long do you think i have to live?" what is the most appropriate respon
AleksandrR [38]
<span>The most appropriate response would be for the nurse to ask the patient about their current concerns. This allows for the patient to actually elucidate what he or she is feeling at the time and does not hamstring the provider into actually giving a set length of time that they feel the patient has left to live, which can vary greatly from person to person.</span>

Ede4ka [16]
<span>Insects are found in almost all ecosystems on Earth, with the rarity being oceans. While some species, such as coconut crabs, sand hoppers, woodlice and pill bugs dwell on land, crustaceans are generally found in water — and usually oceanic — regions. Adapting to their habitat, many insect species evolved wings — two pairs for most and one pair for others. A tracheal system is also present for breathing. Crustaceans, on the other hand, breathe using gill-like mechanisms.</span>

Which section of the pre-mrna contains the protein-coding regions
raketka [301]

The exons of the pre -mRNA contain the protein -coding regions.

Pre mRNA is the first made mRNA transcript and requires undergo many post transcriptional modifications for the formation of a mature mRNA.

The exons are the regions of the pre-mRNA that are found in the mature RNA, after the splicing of introns takes place.

RNA splicing is the process in which the non-coding segments of the RNA, which are known as introns, are removed by the help of small nuclear ribonucleoproteins.  These SnRNPs make the spliceosome, which catalyzes the process of splicing.

After the introns are removed by the splicing process, the exons are covalently joined, which forms the mature mRNA.
