Answer: D. 2-1-3
Explanation:
Hemostasis can be define as a process which causes bleeding to stop when an injury occurs .This process is carried out through this 3 steps;
Vascular Spasm or Vasoconstriction : In this step, the body constrict the blood vessel to reduce the flow of blood to the affected area.
Formation of the Platelet Plug : In this step the body respond by activating platelets which encounters the affected area, becomes sticky and forms a plug that serves as a barrier against blood flow.
Coagulation: Involves the formation of a blood clot. It is a complex process that has Fibrin as it's end product. Fibrin is more like a glue that holds the platelets plug together.
The Fibrin clot gains strength and then dissolves when the walls of the affected blood vessels close and heals.
<span>A
section of DNA that is not expressed in the gene product is called
intron. The final messenger RNA molecule is called exon. Eukaryotic cells have
the enzyme to cut off the intron section to produce a continuous strand
of mRNA so that protein synthesis can occur. Prokaryotic cells can
express the information to produce protein directly as the mRNA does not
contain intron. </span>
