Which will be an appropriate hypothesis for the experiment? (salt) and an egual amount of water as the cell. In this case the water moves equallyOsmosis is the process where water moves across a selectively permeable cell membraneThe term isotonic describes a solution which has an equal concentration of soluteThe term hypotonic describes a solution which has less solute (salt) and morewater, The process of osmosis must be tightly controlled by çells, otherwise they will die.with proteins and salts dissolved in it, preventing the unnecessary gain of water by ourby diffusion. Water moves from the solution with more water to the solution with lessFor example, if you place a red blood cell in pure (distilled) water, it will quickly take upinside the cells and the plant can no longer support itself against the pull of gravity.The term hypertonic describes a solution which has more solute (salt) and lesssolvent (water) than the cell. In this case the cell will lose water.In plants, osmosis is just as important, Plants with too little water will wilt. This happenswater until it bursts. That is why plaşma, the liquid portion of our blood is made of waterwhen water moves out of the cells by osmosis, Without this water there is little pressureHowever, atter watering the plant, the cells become re-inflated with water and the plantstands upright. The effect of water loss on plant cells is shown in the diagram below.9/28/21Osmosis ExperimentBackgroundblood cells.solvent (water) than the cell In this case the cell will gain waterinto and out of the ell.H2OH.OH20CABFigure 1A. Plant cell placed in pure water. This cell will become inflated because the water outsidethe cell is at a higher concentration than the water inside the cell. As water moves in byosmosis the vacuole fills up and presses out against the cell wall.B. Plant cell in salt solution equal to the concentration inside the cell, This cell has nooverall gain or loss of water because whatever moves out will be replaced by water movingin.47 C. Plant cell placed in a salt solution greater than the concentration inside the cell. Thiscell will lose water as the water moves by diffusion from higher to lower concentration.In this lab activity you will observe the effects of osmosis on plant cells. You will use theweight of cubes of potato to see how much water moves in and out of cells in differentsalt solutions.

If the results of an experiment to test your hypothesis show your hypothesis to be wrong: O the experiment was a failure. O you can make a new hypothesis and test it! O you need to redo your experiment until you prove your hypothesis correct! O you didn't follow the scientific method. O You can just fake your results
Explain
Is one anomaly enough to disprove a hypothesis? If not, how many are? Why is it important that scientists use all of their results and not just some of them? What should we do if the evidence neither supports nor contradicts the hypothesis?
