The half-life of a hormone is the time it takes for half of it to be eliminated. In this case, the half-life is 20 minutes.

Step 1: After the first 20 minutes (one half-life), 50% of the original hormone remains.

Step 2: After the next 20 minutes (another half-life), half of the remaining 50% is eliminated. This leaves 25% of the original hormone.

Step 3: After the final 20 minutes (the third half-life), half of the remaining 25% is eliminated. This leaves 12.5% of the original hormone.

So, after an hour, 12.5% of the original number of molecules remains.
