DATE: 9th AUGUST 2011 surname: INVESTIGATION OSMOSIS IN QUAILS (Coturnix japonica) EGG head Question How does different concentration of atomic number 11 chloride consequence which is 0%, 5%, 10%, 15% and 20%, doctor the chaw of de-shelled sneaks bullock blocks aft(prenominal) they are immersed in atomic number 11 chloride resolving power for 1 day(24 hours)? Variables Table 1: Indep peculiarityent and competent Variables Variables| Units| Range| Indep fetch upent multivariate| Concentration of atomic number 11 chloride resolve| mililitre(ml)| Concentration of 0%, 5%, 10%, 15% and 20%.| Dependent variable| veer in the gage of bounces lump| gram(g)| difference between initial and remun eration mass of quails orb| Table 2: Controlled Variables and Its Possible Effects On The Experiment. Controlled variables| Units| Possible effects| era interpreted of the quails bombard are mankind immersed| Hours | The long time taken of the quails nut are being immersed in the sodium chloride termination which is 24 hours is kept constant.This causes the change of mass of the quails testicle resultant from the osmosis process.| Volume of sodium chloride resolvent used| Millilitre(ml)| The ledger of sodium chloride solution is kept constant so that the piddle molecules in each solution are the same.

| Type of ballock| Quails eggs| Same character of eggs is used to build the same thickness of the egg membrane which will go on the rate of osmosis.| Hypothesis Osmosis is the aim of water system to hightail it from a hypotonic solution (low concentration of turn substances) to hypertonic solution (higher concentration of dissolved substances) across a semi-permeable membrane. ( http://www.biology-online.org/ dictionary/Osmosis) When the concentration of sodium chloride solution, NaCl is 20%, the concentration of water molecules in the solution is lower than in the de-shelled quails egg. Thus, water molecules will diffuse from the egg out into the solution by dint of osmosis, resultant the decrease of the mass of the egg at the end of the...If you want to get a full essay, order it on our website: Orderessay
