which proteins were separated by size exclusion chromatography and the relative size of the two proteins

Size exclusion chromatography (SEC) separates molecules based on their size by filtration through a gel. ... Consequently, molecules separate based on their size as they pass through the column and are eluted in order of decreasing molecular weight (MW).

proteins is the answer

9, 5, 10000000 ( that is supposed to be a ten for the last one)
