van der Waals correct answer: -weakest (short lives) but lots could strengthen the bond -furthest distance -form as a result of hydrophobic interactions -strength depends on the size of the atoms and the distance between them -cannot be closer than the Van der Waals contact distance or else positively charged nuclei will repel each other (energy= 0) Proteins correct answer: main action molecule of the cell (Most chemical processes of the body are carried out by proteins) -classified in...
