Explanation / Answer

(1)

B. Dissolves fibrin clots

Streptokinase is a fibrinolytic enzyme, it dissolves the fibrin clots. Used as a medication in myocardial infarction to lyse bood clots.

(2) C. Polysaccharides: one of the components in a biofilm

Biofilms may form on living or non-living surfaces. Extracellular DNA and Polysaccharide matrices typically enclose bacterial biofilm. In Dark field microscopy, the field around the specimen is generally dark.
