The initial [-OH] is 0.250M since NaOH releases 1 mole of -OH per mole of base. Using Kw=[H+][-OH], [H+]=(110^-14)/0.250=410^-14M (note remember units). Hence the initial pH=-...

All proteins are polymers of amino acids arranged with varying degrees of complexity. The most basic structure is the order of amino acids, this is called the primary structure. Amino acids form peptide b...

Darwin made four key observations in his studies of wild populations: members of a population of the same species vary in their traits; traits can be inherited, or passed from parents to offspring; popula...
