I think c is the correct answer
super position
Explanation:
because because it is arranged in a sequence
Platelets start a clotting reaction that intimately produces a clot composed of fibrin, is a form of Fibrinogen
Explanation:
Fibrinogen is blood plasma Protein which is converted into those protein fibrins in the clotting process. After removal of clot the fibrinogen free fluid is obtained and this fluid is known as blood serum. It shows strong flow birefringence. It is highly viscous.
By half saturation process and using the sodium chloride fibrinogen can be participated from the blood plasma. Through thrombin process clotting is initiated. With the help of electron micrographs, its molecules look like a rod whose length is 47.5 nanometre.
