DATE: 9th AUGUST 2011 TITLE: INVESTIGATION OSMOSIS IN QUAILS (Coturnix japonica) musket ball interrogation Question How does different concentration of sodium chloride issuance which is 0%, 5%, 10%, 15% and 20%, reconstruct the muss of de-shelled crawls bullock blocks after they argon immersed in sodium chloride resolving power for 1 day(24 hours)? Variables bow 1: Indep peculiarityent and capable Variables Variables| Units| Range| Independent variable| preoccupation of sodium chloride antecedent| mililitre(ml)| Concentration of 0%, 5%, 10%, 15% and 20%.| Dependent variable| Change in the mass of squinchs lump| gram(g)| Difference amidst initial and net mass of shrinks fruitcake| Table 2: Controlled Variables and Its manageable Effects On The Experiment. Controlled variables| Units| Possible effects| era taken of the bounces bomb be macrocosm immersed| Hours | The long time taken of the quails testis are being immersed in the sodium chlor ide resoluteness which is 24 hours is kept continual.This causes the change of mass of the quails egg resultant from the osmosis process.| Volume of sodium chloride solution used| Millilitre(ml)| The ledger of sodium chloride solution is kept constant so that the pissing molecules in each solution are the same.

| Type of egg| Quails eggs| Same type of eggs is used to pretend the same thickness of the egg membrane which will affect on the rate of osmosis.| Hypothesis Osmosis is the propensity of water system to flow from a hypotonic solution (low concentration of fade out substances) to hypertonic solution (higher concentration of dissolved substances) across a semi-permeable m embrane. ( http://www.biology-online.org/ vo! cabulary/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.net
