The dielectric constant of hexane is 1.88 at 25 °C. Its dipole moment is 0.08 D.
The first system to classify blood types is known as<u> A-B-O system</u>.
<u>Option: D</u>
<u>Explanation:</u>
The blood group system "ABO" is the categorizing of human blood centered on the hereditary characteristics of red blood cells means erythrocytes as measured by the presence or absence of A and B antigens on the surface of the red cells. Thus individuals may well have blood type A, type B, type O or type AB.
It was absent until 1900, when Karl Landsteiner established the concept at the Vienna University why some blood transfusions were effective while others were lethal. Landsteiner established the blood group mechanism ABO by combining each of his staff's red cells and serum.

The solution before dilution and after dilution contains same number of moles, and water is added for dilution.
Option B
<h3><u>Explanation:</u></h3>
Suppose before dilution, the solution contains x moles of KCl in Y liter of water. Now as the concentration got halved, then the solution contains x moles of KCl in 2Y kiters of solution. So the number of moles of KCl in the solution remained constant.
Again, as the solution is diluted to half of the concentration, water must have been added with the solution to make it dilute.
