During the urinalysis lab, how many patients did you test? c. 5 48. During the urinalysis lab, did you test for protein in all the patients. a. Yes b. No 49. Specific gravity is measured to the nearest.. a. 0.01 b. 0.001 c. 0.0001 50. True or false: Tubular filtrate is similar to blood plasma in composition except that large molecules over 70,000 MW are included (plasma protein)

Answer 1

Ans.43 True , the kidney regulates the concentration of ions, water and pH.Each kidney has nearly one million complex tubular structures called nephrons.Each nephron has two parts - the glomerulus and the renal tubule.The renal tubule consist of proximal convoluted tubule (PCT) helps to maintain the pH and ionic balance of the body fluids by selective secretion of hydrogen ion, ammonia and potassium ion into the filtrate and by absorption of HCO^​-_​​​3​​ from it. Further Henle's loop plays a significant role in the maintainance of high osmolarity of medullary inerstitial fluid.Distal convoluted tubule (DCT) reabsorb sodium ion and water.Collecting duct allows passage of small amounts of urea into the medullary interstitium to keep up the osmolarity .It also plays a role in the maintenance of pH and ionic balance of blood by the selective secretion of hydrogen ion and potassium ion.

Ans 44.(b) protein.The chemical test used for detecting the presence of peptide bond.Biouret reagent is a blue solution when it reacts with protein, will change color to pink-purple.

Ans 45.(c) starch.Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine.

Ans 46.(a) sugar.A test with Benedict's reagent is shown by a color change from clear blue to a brick-red precipitate due to the presence of reducing sugar.
