Answer:
d.They prevent the two parental strands from coming together again.
Explanation:
During the process of DNA replication, the two DNA strands should be separated from each other to serve as a template. To separate the two DNA strands, the helicase enzyme breaks down the hydrogen bonds between the complementary base pairs of the DNA strands. The process uses ATP as a source of energy.
Due to the presence of complementary base pairs, the separated DNA strands have a tendency to reanneal by the formation of hydrogen bonds. To prevent the reannealing of separated DNA strands, single stranded binding proteins bind to them. Binding to single stranded binding proteins to the separated DNA strands does not allow them to reanneal.
More blood vessels are stimulated to vasoconstrict more than vasodilate because blood vessels contain more alpha receptors than beta receptors.
<h3>What is Vasoconstriction?</h3>
This is the process which involves the narrowing of the blood vessels through their muscle wall.
They contain more alpha receptors such as Alpha-adrenoceptor agonists than beta receptors which mimicks the effects of sympathetic adrenergic nerve activation to the blood vessels.

<span>The nurse conducting wound care should choose a dressing that
keeps the periwound skin dry and the surgical wound bed moist to contribute
healing. The dressing used for wound care should control exudate from the
wound, but it should not desiccate the wound bed. There must be a pressure in
application while cleaning the periwound and wound may deepend the wound bed. Using
sterile normal saline and a sterile gauze to clean the surgical wound reduces
the incidences of infection.</span>
