Answer
The correct answer is D, which shows that the pancreas produces insulin, a hormone that plays a crucial role in the control of blood glucose levels.

Answer
The target organ for insulin is the liver. Insulin facilitates the uptake of glucose by the liver, where it can be stored as glycogen.

Answer
Adopt a balanced diet that is low in sugar and refined carbohydrates, which helps to stabilize blood glucose levels.
Engage in regular physical activity, such as walking or cycling, to enhance insulin sensitivity and glucose metabolism.

Answer
The trend in Figure 12 shows that as the speed of running increases, the respiration rate increases significantly. While sleeping, the respiration rate is low at 3 kJ per minute. When running slowly, it rises to 90 kJ per minute, and then to 130 kJ per minute when running quickly. This upward trend indicates that physical activity increases the demand for energy, which leads to higher rates of respiration to meet the body’s energy requirements.
