Sample questions
A graph showing the effect of increasing concentration of a hormone 'X' on blood glucose levels is provided. Initially, with low concentration of X, blood glucose is high. As concentration of X increases, blood glucose decreases significantly. Identify hormone 'X' and its site of secretion. [Diagram description: A line graph with 'Concentration of Hormone X' on the X-axis (increasing from left to right) and 'Blood Glucose Level' on the Y-axis (decreasing from top to bottom). The line starts high on the Y-axis at low X concentration and slopes downwards steeply as X concentration increases.]
