<span>The medication that should cause the nurse to pause and then review the serum blood level of the client is Valporic Acid, or Depakene. Valproic acid is only effective when it reaches the therapeutic level, the level of the serum must be watched to check for both toxic levels and therapeutic levels of the medicine.</span>
Answer:
Artificial selection, also called "selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.
A cell replicating itself.
Answer:
Explanation:
In the structure of Nucleic acids the nucleobases (nucleotide and bases) are arranged is a specific form.This form of arrangement is called Base stacking.It simply refers to the bond formed between the adjacent bases.
These nitrogenous bases of (A,T,C.G) pairing in DNA are in planes in geometry.The bases planes stack with one another.This form of arrangement give rooms for more Van der Waals interactions in the plane of the bases.Although the Van der Waals are weak interactions,the bond ensure that these bases are braided or twisted together to give maximum energy,to maintain stability of the bases,and therefore of DNA structure
Therefore in water and other aqueous solution the stability of structure of DNA is enhanced by the base stacking,(coiling or twisting)with maximum van der waals interaction among the bases, than the hydrogen bonds formed between bases.Generally there are more stacking among G-C,than A-T,thus the former pairing contribute more the structural stability than the latter (A-T)
