For example, an individual with diabetes will pass urine, in which glucose is constituent. Therefore, testing for glucose in urine will help in diagnosing diabetic patients. Answer and Explanation: The answer is a) red-orange. Benedict's tes...
An analytical element for quantitatively determining high levels of glucose in blood is made by (a) impregnating a carrier with a first solution, having dissolved therein 4-aminoantipyrine and 3-hydroxy-2,4,6-triiodobenzoic acid or 3,5-dichloro-2-hydroxy-benzene sulfonic acid or salts thereof,...
The researchers asked the diarists recruited to say how often they made entries and for how long they had kept diaries. They were also asked if they had written about anything traumatic. (Paragraph 7, Passage 1) 3. Growth is defined as a change in body size and structure; development is ...
In lab, we used Benedict's reagent to test forone particular reducing sugar: glucose. Benedict's reagent starts out aqua-blue. As it is heated in the presence of reducing sugars, it turns yellow to orange. The "hotter" the final color of the reagent, the higher the concentration of redu...
