Answer 2

1. The bleeding would stop because the plasma and platelets present in the blood wild clot it and stop it from flowing out . Seen through a microscope, the plasma and platelets would form a net like structure with extremely minute holes around it which stops the Red blood cells from flowing out and the blood stops.

2. As the plasma and the platelets would gather over there they would form a clot . This clot is of brownish colour which heals over time . Thus the colour of the wound over that area would be brownish.
