1.Only cells having specific receptors for a hormone can respond to the hormone's presence.
2.The hormones only go to some cells in the body but not to others.
3.Special molecules on cells that are not affected break down the hormone before the cell can recognize it.
4.Some cells have the wrong temperature to respond to the hormone.

Answer 1

1. Only cells having specific receptors for a hormone can respond to the hormone's presence.

Answer 2

Hormones, Receptors and Target Cells. ... Most hormones circulate in blood, coming into contact with essentially all cells. However, a given hormone usually affects only a limited number of cells, which are called target cells. A target cell responds to a hormone because it bears receptors for the hormone.

I did my research. if this doesn't help just say so and ill look again.
