<span>The nurse is caring for a patient who is on patient-controlled analgesia (PCA). Which action made by the nurse prevents air formation in the intravenous tube? 2</span>
<span>A
section of DNA that is not expressed in the gene product is called
intron. The final messenger RNA molecule is called exon. Eukaryotic cells have
the enzyme to cut off the intron section to produce a continuous strand
of mRNA so that protein synthesis can occur. Prokaryotic cells can
express the information to produce protein directly as the mRNA does not
contain intron. </span>
Answer:B
Explanation:
Agonist-induced desensitization involves phosphorylation of G protein-coupled receptors by two currently recognized classes of serine/threonine protein kinases. Second messenger-dependent kinases, phosphorylating a variety of proteins, mediate a generalized cellular hyporesponsiveness termed heterologous desensitization. G protein-coupled receptor kinases (GRKs) phosphorylate specifically agonist-occupied, or activated, receptors, and thereby initiate receptor-specific, or homologous, desensitization.
Answer:
C. The way that the data is organized.
Explanation:
Placing data in a table allows the reader to have a better view and understanding of the data and how each figure is related to the rest, via columns and rows. It also provides a much better organization of the information.
A, B and D are false answers, because the aspects they mention wouldn't be impacted by a paragraph formatting (numbers would stay the same, just a lot harder to read and understand).
Scientists can reduce uncertainty by performing repeated hypothesis testing trough experiments or observations that exhibit the same predictive outcomes.
<h3>What is hypothesis testing?</h3>
The expression 'hypothesis testing' makes reference to experimental and also observational methods used to test (either confirm or reject) a scientific hypothesis.
Hypothesis testing helps to reduce the level of uncertainty because the same results in different outcomes represent an excellent a measure of reliability by means of the scientific method.
In conclusion, scientists can reduce uncertainty by performing repeated hypothesis testing trough experiments or observations that exhibit the same predictive outcomes.
