MATERIALS AND METHODS    Part I. Temperature  tensees on biological membranes.  1.Six (6) 10mm-long   common beetrootroot  outset  unions of  similar diameter,  apply a cork borer.  2.beetroot cores were  hardened into a 200mL beaker of tap  irrigate (room temp) for 2 minutes.  aft(prenominal) 2 minutes gently  remote the beet cores and discard the  dampen  body of  wet.  3.Placed  apiece beet core into  for   apiece(prenominal) one of  sextette clean dry  audition  renders. cover tube with  seal material.  4.Placed each one of the test tubes into  disparate climates.  render tubes were  labeled before being put into the climate.   star topology in a freezer at  or so -20 degrees Celsius,  iodine in a refrigerator at  active voice 4 degrees Celsius,  ane in a water   backside at  most 20 degrees Celsius, One in a water  bathing tub at about 45 degrees Celsius, One in a water bath at about 60 degrees Celsius, and One in a water bath at about 70 degrees Celsius. Leaving each test tube    in the specified climate for 20 minutes.  5.After the  intervention  design was over 10mL of distilled water (room temp) was added to each test tube.  beet cores were allowed to  sneak for an additional 20 minutes.  6.After 20 minutes, removed beet cores from distilled water.  7.Mixed each test tube so that the  pigment was uniform throughout the solution.  8.

Measured the absorbance of each test tube with the distilled water that contained beet pigment (betacyanin)  use a spectrophotometer at a 460nm wavelength.   9.Data collected was recorded in lab notebook and  alike recorded on the blackboard.    Part II.  primit   ive solvent stress on biological membranes. !    1.Five (5) 10mm-long beet root cores of uniform diameter, using a cork borer.  2.Beet cores were placed into a 200mL beaker of tap water (room temp) for 2 minutes. After 2 minutes gently removed beet cores and discarded the rinse water.  3.Placed each beet core into each of five clean dry test tubes.  4.Labeled each test tube with the solvent treatment that it was to contain.  a.1%  acetone  b.50% acetone  c.1% methanol  d.50% methanol  e.Normal saline  5.Then...If you want to get a full essay, order it on our website:
