A healthy adult drank a glucose solution. The adult's blood glucose concentration was at its optimum level before drinking the solution.
| Time after drinking the solution in minutes | Blood glucose concentration in mmol/dm³ |
|---|---|
| 0 | 4.9 |
| 30 | 7.1 |
| 60 | 5.8 |
| 120 | 5.0 |
Which statement gives the best interpretation of the results?
The results show homeostasis because the concentration rose quickly after the drink
The results do not show homeostasis because the concentration at 120 minutes was above its starting value
The results do not show homeostasis because the concentration changed after the drink
The results show homeostasis because the concentration rose and then returned close to its starting optimum
