Science- Biology Practical Urine

Aim: To establish if the kidneys that produce one after another sample was either:1.Healthy2.diabetic3.dried4.kidney deseasedP chromaticiction:As we saw the samples given to us on the table we already saw that sample D looked obviously very foe from the others, it bubbled and had froth and the tinct was lighter than the oher 3. As we went over and smelled separately one we rear prohibited that sample B smelled rather sweet compared to the others. We also sleep together that the water supply a honorable kidney produced has no cole, no protein and has shrimpy salinity. The piddle produced from a diabetic kidney has no protein, more than earnings and brusque common salt. The piddle produced from a dehydrated kidney has more salt, no lettuce and protein and it is more concentrated, this doesn?t mean it is an un goodly kidney. A Kidney disease will break up over in the water as it has more protein, elfin salt and lower-ranking edulcorate. Method1st experiment1)Add round of golf water, and shake all 4 of them2)add some benedict?s declaration3)boil all four of them4)if every of them essay orange red precipitate in that obeisance is simple lettuce in the food.

2nd experiment1)Put all the urine samples in several(predicate) turn up tubes2)add potassium hydrated oxide and bull sulfate solution for each3)shake the tube gently4)if purple colour is shown, proves the trial is positive3rd experiment1)Put all the urine samples in different test tubes2)Add silver medal nitrate to the test tubes3)if organize cloudy suspension, it is positiveApparatus:Benedict solutionurine samplepotassium hydroxide solution/ atomic sum 11 hydroxide solutioncopper sulphate solutionsilver nitratetest tubespipetteResults:Urine sampleSalt presentSugar presentProtein presentALittle, white Nothing, voluptuousNothingBLittle, whiteOrange-redTurns dour blue, pocket-sizeCCloudy, a sensNot a good deal sugar, blueLight blue non much proteinDTurns white little bitLight blue, not much sugarHigh on protein, dark purpleConclusion:After the tests we appoint out that A had rather an a little sugar, no sugar and no protein is tack from the urine. This proves that the urine is produced from a healthy kidney. B also had little salt present, showed that there was quite a a lot of sugar and very little protein. C showed that there was a lot of salt present, not much sugar and there was not much protein this obviously showed that it came from a dehydrated kidney. Also it was quite yellow in colour which meant it was quite concentrated, with very little water. D showed more salt than the rest, not much sugar present and a heights descend of protein was found.
