depressed; it is important to know whether the client is considering suicide so
the nurse can provide a safe environment and related therapeutic care. Concern
for the client's safety takes priority at this time over the client's feelings,
the underlying cause of the behavior, or the dynamics of the marital
relationship.
<h2>Replication </h2>
Explanation:
Meselson and Stahl began the experiment by growing E. coli in medium, or nutrient broth, containing a "heavy" isotope of nitrogen
When grown on medium containing heavy nitrogen the bacteria took up the nitrogen and used it to synthesize new biological molecules including DNA
After many generations growing in the heavy nitrogen, the nitrogenous bases of the bacteria's DNA were all labeled with heavy nitrogen and then the bacteria were switched to bacteria containing a light nitrogen and allowed to grow for several generations
They then measured the density of the DNA using density gradient centrifugation
Results obtained contained heavy DNA,Light DNA and hybrid of Light and heavy DNA
The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand
Had it been conservative mode of replication, DNA replication would have resulted in one molecule consisting of both original DNA strands (identical to the original DNA molecule) and another molecule consisting of two new strands (with exactly the same sequences as the original molecule)
The answer would be A. meteoroid that travels through earths atmosphere and hits the surface.
