Hi, Can someone please let me know the 'difference in meaning' of the following two sentences: Margaret found how the body has an unlimited number of antibodies, each specifically targeted at a hostile substance. This version implies tht something outside the antibodies is responsible for the targetting, eg each specifically targeted (by the body, by the person's immune system, by ***) Margaret found how the body has an unlimited number of antibodies, each specifically targeting a hostile substance. T his version just says more simply that this is what the antibodies do.
