Answer:
Both of the regular intravenous solutions administered in medicine, normal saline and lactated Ringer’s solution, are isotonic. Why is this important?
Explanation:
<em>Because the isotonic saline solution</em> has a sodium concentration similar to that of blood.
ISOTONIC SOLUTIONS: <em>The osmolarity of the isotonic fluid approximates the osmolarity of serum plasma. </em>Isotonic fluids are used to hydrate the intravascular compartment in situations of significant fluid loss, such as dehydration, bleeding, etc.
It contains a cellular membrane which separates the interior of the cell from its environment.
The correct answer is that it produces antibodies against the sensitizing antigen.
Plasma cells are formed in the bone marrow, the B cells divide into plasma cells, which generate molecules of antibody. Once discharged into the lymph and blood, these antibody molecules combine with the target antigen, that is, foreign substance and starts its destruction or neutralization.
The correct answer is an active site.
The active site, in biology, refers to the region of an enzyme where the molecules of substrate combine and goes through a chemical reaction. The active site comprises of the residues, which produce temporary bonds with the binding site (substrate) and residues that catalyze a reaction of that substrate, that is, the catalytic site.
