If a bond has a 7% nominal yield or coupon and was purchased at a premium of $103 ($1030), then your YTM will calculate lower because the 7% interest is only paid to the $1000 par.

E. coli is the type species of the genus (Escherichia) and in turn Escherichia is the type genus of the family Enterobacteriaceae, where the family name does not stem from the genus Enterobacter + i (sic.) + aceae, but from enterobacterium + aceae (enterobacterium being not a genus, but an alternative trivial name to enteric bacterium).
