Worked Solution & Example Answer:People with diabetes have difficulties regulating their blood glucose concentration - Edexcel - GCSE Biology - Question 5 - 2012 - Paper 1
Step 1
Describe the overall trend shown in the graph.
Answer
The overall trend in the graph shows that the percentage of the population with Type 2 diabetes has increased from 1993 to 2000. The values start at approximately 4.5% in 1993 and rise steadily, reaching about 7.5% by 2000. This indicates a positive correlation between the years and the percentage of individuals diagnosed with Type 2 diabetes.
Step 2
Calculate the change in the percentage of the population with Type 2 diabetes between 1993 and 2000.
Answer
To calculate the change, we subtract the percentage in 1993 from the percentage in 2000:
Final value (2000) = 7.5% Initial value (1993) = 4.5%
Change = 7.5% - 4.5% = 3%
Thus, the change in the percentage of the population with Type 2 diabetes between 1993 and 2000 is 3%.
