While sexual reproduction in eukaryotes results in offspring with genetic material which is a mixture of the parentsâ genome, a prokaryote will reproduce clones of itself. During reproduction, eukaryotes generate genetic variation by sexual recombination.
Diamonds Are a Girl's Best Friend by Ethel Merman. This song was written by Jule Styne and Leo Robin for the Broadway production of Gentleman Prefer Blondes and was first performed by Carol Channing in 1949. Ethel Merman, the actress and singer known for her vibrant voice and magnetic stage presence, recorded it the following year.
Diamond will always be a girlâs best friend, but it may soon lose favour with industrial drillers. The gemstone lost its title of the âworldâs hardest materialâ to man-made nanomaterials some time ago. Now a rare natural substance looks likely to leave them all far behind â at 58 per cent harder than diamond.
