Alum stops bleeding in minor cuts because of – (1) solvation (2) emulsion (3) dialysis (4) coagulation

Alum stops bleeding in minor cuts because of – (1) solvation (2) emulsion (3) dialysis (4) coagulation
by

1 Answer

Answer :

(4) coagulation Explanation: Coagulation is the process by which blood forms clots. It is an important part of homeostasis, the cessation of blood loss from a damaged vessel, wherein a damaged blood vessel wall is covered by a platelet and fibrincontaining clot to stop bleeding and begin repair of the damaged vessel. Disorders of coagulation can lead to an increased risk of bleeding (hemorrhage) or obstructive clotting (thrombosis).
