Correct answer: B. Sixty to ninety minutes
1. Half-life is how long it takes for half the hormone to be cleared.
2. Cortisol is a lipid-derived hormone and lasts far longer than a nerve signal.
3. Its half-life is approximately 60 to 90 minutes.
4. So the answer is measured in minutes rather than seconds.
