4. The answer is that when the line reaches zero on the horizontal axis then there will be little left of the Isotope. This, in turn, means that it will keep getting smaller but never stop existing. I know, when my dad explained it to me it sounded complex but it basically means that it will keep getting smaller until it is not able to be distinguished between none and little to none.
If you are really still struggling I suggest you watch a brain pop about this and look over your lesson. Hope this helps.
