Because hemoglobin is compartmentalized inside the RBCs, lysis of RBCs is necessary for accurate measurement of hemoglobin levels.
<h3>Measure of hemoglobin concentration</h3>
Hemoglobin is a complex found in blood which is responsible for transporting oxygen to cells of the body.
Hemoglobin is composed of heme and the proteins alpha and beta globin.
Hemoglobin is found within the cytoplasm of red blood cells.
Since hemoglobin is compartmentalized inside the RBCs, lysis of RBCs is necessary for accurate measurement of hemoglobin levels.

With shorter necks, giraffe ancestors could not reach food-containing branches on tall trees. This resulted in the directional selection of giraffes with longer necks.
<h3>
Why is choosing a direction necessary? </h3>
It nearly appears obvious that the giraffe's long neck developed as a result of a lack of food in the lower branches of trees. The giraffe has a significant advantage because it is taller than any other mammal and can feed where few others can.
When compared to modern giraffes, the giraffe's ancient predecessors had a shorter neck. The plants that were lying at a higher level were inaccessible to them. Giraffe phenotypes have changed in various ways, and now have long necks to reach vegetation that is higher up. The extreme form is chosen above other features in directional selection. It was decided to choose the long-necked giraffe over the short-necked.
