Final answer:
Type I diabetes represents about 5% of those with diabetes, which is answer A) 5%. It is an autoimmune disease leading to insulin dependence, while type 2 diabetes, accounting for about 90% of cases, is often associated with lifestyle factors and insulin resistance.
Step-by-step explanation:
Type I diabetes typically develops early in life and represents about 5% of those with diabetes. The correct answer to the question is A) 5%. Type 1 diabetes is an autoimmune disease that can develop due to a T-cell-dependent autoimmune response, which leads to the destruction of the beta cells in the pancreas. These beta cells are responsible for producing insulin, and without them, individuals must rely on synthetic insulin to manage their blood sugar levels. In contrast, type 2 diabetes accounts for approximately 90% of all diabetes cases and is characterized by insulin resistance. This form often develops in adulthood and is strongly associated with lifestyle factors such as poor diet, lack of exercise, and being overweight or obese. While type 2 diabetes is more prevalent, type 1 diabetes is still an important and serious condition that affects a smaller percentage of the diabetic population.
