Diploma Alert: Highlighted words have special meanings for the diploma exam. Questions using these words will be using the diploma interpretation. Please go to page 761 in your textbook for the meanings you should be using for these words.

Hint: A helpful note: Sometimes marks are awarded for stating  that glucose changes colour in the presence of Benedict's. In this question there are no marks given for this explanation. More detail is required, refer to page 213 for a review of "testing for sugars".

Over time, the color changes of Benedict's in the presence off glucose are:  from blue → green → yellow → orange → brick red, depending on the concentration.

Note: Page 761: Interpret is to give meaning to the original data, it is not TO EXPLAIN.



Question 2: Explain the results obtained.  

5 marks: Patient A (2marks), Patient B (1 mark), and Patient C (2 marks).

NOTE: You are expected to detail the role of insulin.

See Page 761: Explain means, to give the cause of, make known in detail. If you do not include what happens in the liver you would lose marks.
