TRUE OR FALSE 1. In culturing C. elegans, microorganisms like E. coli is used as their food and nutrient source. 2. Rats are easier to handle and perform procedures than mice since they are large in size. 3. Rats are better organism models compared to rabbits in the study of diabetes.

1- Compared to the above urine test, if a blood test for glucose correctly identifies 95% of diabetic patients, but gives false-positive results for 10% of non-diabetic patients, then: the blood glucose test has improved sensitivity, but reduced specificity (compared to the urine test) the blood glucose test has improved both sensitivity and specificity (compared to the urine test) the blood glucose test has improved specificity, but reduced sensitivity (compared to the urine test) the blood glucose test has reduced both sensitivity and specificity (compared to the urine test) the blood glucose test has improved neither sensitivity nor specificity (compared to the urine test)
