06.4 · 2 marks Choosing participants for glucose testing People with Type 1 diabetes were selected for the investigation instead of people who did not have diabetes. Explain why. 06.6 · 1 mark Blood-glucose investigation safety It was important for the scientists to monitor the health of each person during the investigation. Suggest one reason why. 06.7 · 2 marks Homeostasis and optimal reaction time People who do not have diabetes usually have a blood glucose concentration in the range of 4.0 mmol/dm³ to 7.8 mmol/dm³.... 06.8 · 5 marks Hormonal control of blood glucose Describe how blood glucose concentration is maintained within narrow limits in people who do not have diabetes. 06.9 · 2 marks Synaptic transmission and reaction time Describe how an increase in the chemicals could decrease reaction time. 06.1 · 1 mark Endocrine gland coordination Which gland releases hormones to control other glands? Tick one box. 06.3 · 1 mark Detection in homeostatic systems Cells in the pancreas detect changes in blood glucose concentration. What type of cell in the body detects changes?
