Can you please help me and explain step by step with details. Thank you!

The change of state from gas to uquerd make us think that the entropy favors the reactents. However, the hydiogen bonds forms in the lquad state allows a very stable State 25. You are given a sample containing three polypeptides with molecular weights of 10, 20, and 50kDa. Two samples are prepared with this mixture, one that contains all of the components needed for SDS-PAGE including prepared with this mixture, one that contains all of the components needed for SDS-PAGE including - mercaptoethanol (+BM) and a second sample that lacks -mercaptoethanol (BM ).
