Question 2 of 31 3.0 Points What are the monomers that make up proteins? .  A. steroids  B. amino acids  C. oils  D. DNA Feedback:Great job. Question 3 of 31 3.0 Points What is the capacity of a substance to withstand rupture when placed under tension or stress?  A. surfact tension  B. adhesion  C. cohesion  D. covalent bond  E. solvent Feedback:Water molecules are attracted to each other because of hydrogen bonding by cohesion – and this gives rise to surface tension.
