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.

Answer:
10 % of the energy. This efficiency of energy transformation is high
Explanation:
The infant is suffering from dehydration most probably from esophageal atresia (non-development of the distal side of the esophagus, forming a closed tube) or partial/complete gut obstruction. With a urine output of 250 mL constantly, the patient will be dehydrated. The infant is diagnosed with failure to thrive and is most probably malnourished (most common cause of failure to thrive in infants is preterm birth). In the presence of esophageal atresia, along with retained feedings, the patient will also present with vomiting. In the presence of partial/complete gut obstruction, the patient will also present with distension of the abdomen.
The correct choice from given option is "D", "Lactobacillus"
It seems proper to explain a bit about the types of cells here. Two type of cells are:
1) Prokaryotic: these cells have no nucleus and they are small and simple.
2) Eukaryotic: These cells have a nucleus and are large and complex as opposed to prokaryotic.
"Lactobacillus" belong to first stated category here.
Answer:
Recycled Ammonia
Explanation:
Ammonia can be extracted from livestock wastewater and used as a fertilizer. There are systems available that extract the ammonia and mix it with acids to create ammonium citrate or ammonium nitrate, both of which can be used as fertilizers. The extraction system removes ammonia from the waste, which significantly reduces the amount of ammonia that is released into the air. This has the added bonus of improving the air quality where animals are kept.
