A biologist is a scientist devoted to and producing results in biology through the study of life. Typically biologists study organisms and their relationship to their environment. Biologists involved in basic research attempt to discover underlying mechanisms that govern how organisms work. Biologists involved in applied research attempt to develop or improve medical, industrial or agricultural processes.
A "strong" acid (or base) is one that dissociates completely in dilute aqueous solution. One which does not is a "weak" acid (or base). An acid with a pKa (or a base with a pKb) lower than about -2 is considered to be a "strong" acid.
Weak acids and bases can still be quite corrosive. HF is a "weak" acid with a pKa of around 3.2 (which corresponds to only about one molecule out of every 38 or so being dissociated), but it's pretty terrible stuff and will dissolve even glass.
