Answer:
Here is the complete question
The initiation of transcription requires melting of the DNA double helix, i.e. separating hydrogen-bonded base pairs, immediately upstream of the +1 site. In E. coli this melting is accomplished by ___________.
-DNA helicase unwinding the double helix around the +1 site.
-DnaA:ATP complexes binding to and twisting the double helix at the +1 site.
-RNA polymerase obtaining the energy to cause separation of strands from ATP hydrolysis.
-binding of the DNA complexes to the double helix at the +1 site and twisting of the double helix.
-bases at the promoter region flipping outward from the double helix into pockets on the polymerase.
And the answer is.....
bases at the promoter region flipping outward from the double helix into pockets on the polymerase.
The correct answer for the question that is being presented above is this one: "B. Aldosterone-regulated Na+ pump activity would increase dramatically to stabilize the osmotic concentration gradient."
Here are the following choices:
<span>A. The final urine output would increase greatly because of the increase in ADH-regulated water reabsorption.
<span>B. Aldosterone-regulated Na+ pump activity would increase dramatically to stabilize the osmotic concentration gradient.
</span>C. The increased solute concentration in the vasa recta would stimulate additional water reabsorption.
</span><span>D. The concentration gradient of the renal medulla would remain unaffected.</span>
Answer: Replication is called semiconservative because each of the original strand is is used as a template for the synthesis of a new strand
Explanation: DNA is a double-stranded helix containing two antiparallel strands that are complementary to each other.
Replication is the process of making identical copies of a DNA molecule. Before replication begins, the double-stranded DNA is first unwound by helicase so that each strand will serve as a template for new strand synthesis.
DNA replication is semiconservative because each DNA strand serves as a template for the synthesis of a new strand, producing two new DNA molecules each one with one new strand and one strand.
Saved and used in the new strand
High quantities of nutrients in water from industrial crop fertilizers and animal waste cause excessive aquatic plant growth — a process known as “eutrophication,” which, in turn, causes “hypoxia,” or water that is low in oxygen. Harmful algal blooms (or HABs) occur when aquatic algae grow rapidly out of control.
