The decalcified eggs will be weighed before and after being put in the solutions. The zero and ten percent solutions are hypotonic‚ so the eggs should gain weight. The twenty percent solution is isotonic and the weight should primarily stay the same. The forty percent solution is hypertonic‚ so the weight should decrease. (Muller) Experimental Procedure Eight eggs are placed in a medium glass bowl and covered in vinegar. (Although‚ we only need four

Water molecules move from high to low Osmosis is what they seem to know Solute and Solvent are what’s inside The polarity of water makes it easy to find “Hyper” and “Hypo” tells you how much is there But isotonic means that they are fair Water molecules move from the inside out Scientists call this plasmolysis without a doubt All of this happens inside a membrane It is a serious matter‚ not a fun little game When a membrane is selective it chooses what it wants Few things are moved through

state‚ they are said to be isotonic. If they differ‚ the solution with a higher concentration of solutes is hypertonic with respect to the other; the solution with lower concentration is hypotonic. Water potential describes the tendency of water moving to another area. Since solutions always tend to reach a state of equilibrium‚ water usually moves from a hypotonic solution to a hypertonic solution in order to dilute the higher concentration. Therefore‚ we say that hypotonic solutions have a lower solute

increasing the concentration of the ECF. Hypothesis This is the hypotheses that you developed before conducting your experiment. It is hypothesised that when sheep’s RBC are added to a hypertonic solution‚ they will shrivel and occupy less space within a haematocrit tube‚ when compared to a hypotonic solution that will cause the cells to lyse. Materials and methods This is the description you gave of the materials and methods you used to test your hypothesis. We started by using a weighing

putting a piece (or more) of potatoes into glucose or salt solution to see the result of osmosis (a hypertonic type of solution is mostly used as it would give the most prominent visual prove of osmosis‚ as was mentioned in an observation of an experiment). As the potatoes are left in the solution‚ water molecules from the potatoes would move out through the semipermeable membranes to the hypertonic solution surrounding it in an attempt to equalise the amount of glucose/salt within the solution to

is hypotonic to the potato‚ thus water is entering the cell. Meanwhile‚ the cells in the solutions 5% NaCl and 10% NaCl would have shriveled cells. This is because the solution is hypertonic and water is leaving the potato out into the solution.

types of tonicity that one solution can have relative to another. Those are hypertonic‚ hypotonic‚ and isotonic. Hypertonic solutions(more dissolved solute)-the solution with a higher concentration of a solute. Water leaves the cell and the cell shrinks. Hypotonoic solution(less dissolved solute)-the solution with the lower solute concentration. Water molecules enter the cell and the cell becomes larger. Isotonic solution(same amount of dissolved solute)-the solution of equal solute concentration

entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic: Having reduced pressure or tone‚ in particular. * Isotonic solution: a solution having the same osmotic pressure 3. Explain the similarities and differences between diffusion and osmosis. Both are the movement

flexible and stiff. Core A was the most non-adjustable due to it being hypertonic which means that the total concentration of all the dissolved solute particles is greater than the other solution. Core B was isotonic meaning that it had an equal balance throughout. When two environments are isotonic it means that the total molar concentration of dissolved solutes is the same in both of them (equal). When cells are in an isotonic solution‚ movement of water out of the cell is exactly balanced by movement
