Final answer:
The statement that a fibrin clot forms before the platelet plug is false. Platelet plug formation occurs before fibrin clot formation in hemostasis.
Step-by-step explanation:
The correct statement is B) False.
Platelet plug formation is the initial step in hemostasis, which is the process of blood clotting to stop bleeding. When there is an injury to a blood vessel, platelets become activated and change their shape to form a plug at the site of injury. This platelet plug is temporary and helps to prevent further blood loss.
After the platelet plug is formed, the next step in hemostasis is the formation of a fibrin clot. Fibrin is a protein that forms a mesh-like structure, strengthening the platelet plug and trapping more platelets and other blood cells to create a stable blood clot.
Therefore, the correct sequence is platelet plug formation followed by fibrin clot formation.
