Answer:

The geological time scale refers to the arrangement of major and distinguishable events that have taken place in the geological past and also provides a glimpse of how the earth and the organisms have undergone significant evolution over a due course of time. It is based on the presence of fossils on the rocks of various sequences, and also the classification of rock types and the correlation of rocks of different locations.  It shows right from the time of formation of the earth, which is approximately 4.6 billion years ago.

This time scale is one of the main components of geology and is widely used by the paleontologists, geologists and other earth-related scientists, in order to construct the relation of various events that have occurred in the past.

The transfusion reaction that arises from the mixing of incompatible blood types illustrates a/an Hemolytic transfusion reaction.

<h3>Explain the Hemolytic transfusion reaction.</h3>

After receiving blood transfusions, a dangerous complication called a hemolytic transfusion response might develop. The response happens when the recipient's immune system kills the red blood cells that were donated during the transfusion. Red blood cell destruction is known as hemolysis. Other allergic transfusion responses exist that do not result in hemolysis.

<h3>What are the causes of Hemolytic transfusion reaction?</h3>

A high amount of incompatible plasma, which occurs less frequently, and the transfusion of incompatible red blood cells (RBCs) are the two most common causes of acute HTRs that happen during or within 24 hours following the delivery of a blood product. A subsequent immunological reaction to an antigen on the donor's RBCs results in delayed HTRs.
