What is the effect of different solutions with various concentrations on plant cells? Hypothesis: 1. In an animal cell in a hypertonic solution the egg will swell‚ in a hypotonic solution the egg will swell. 2. In a plant cell in a hypertonic solution it will shrink‚ and in a hypotonic solution

Discussion: We have made four set-ups in two different specimens. Onion and Boat of Moses skin with water‚ 2%‚ 5% and 10% salt (NaCl) Solution. Based on our experiment‚ the result of the set up explains that the presence of the salt solution results in outward diffusion of water and the collapse of the protoplast. In table 1‚ we have observed under the microscope that the onionskin mounted with water has no results of plasmolyzed cell (0%). This time‚ we have repeated the procedure with 2% salt

Serial dilutions were performed to prepare a lactase solution as well as twenty percent‚ fifteen percent‚ and five percent concentrations of NaCl. Three different treatments of ortho-nitro-phenyl-galactoside‚ lactase‚ and perspective salt concentrations were prepared in cuvettes where the reaction would be observed and recorded from a spectrophotometer. Larger concentrations of salt adversely

To the extracted liquid‚ 5mL of NaCl was added and put into a separatory funnel to remove the water layer. 5mL of 10% K2CO3 was added to the extracted organic layer‚ and then placed into the separatory funnel for the removal of the water layer. NaCl was then again added to the organic layer‚ and put through the separatory funnel to again remove more of the water layer. After the water removal

concerned with Irish history. Looming over the scene depicted is the spectre of the potato famine that afflicted Ireland from 1845-49. The potato crop‚ staple for the Irish‚ failed‚ and with cataclysmic results. About half the population of three million died‚ while a million people emigrated – many to America. The first section of the poem is written in alternately rhymed quatrains that describe a rural scene of potato digging that is clearly in progress much later than a similar scene around the time
