Question:need 3 examples of isotonic, hypertonic and hypotonic solutions for biology need 3 examples EACH
Answers:Do you know what does isotonicity or hypertonicity and hypotonicity mean???
By the way, 0.9g% normal saline is isotonic to mammals (e.g. Locke's Solution, Tyrode's Solution, and Dale's Solution); 0.65g% normal saline is isotonic to amphibians (e.g. Ringer's Solution). Any saline preparations having salt concentration higher than the isotonic value are hypertonic and less than that are hypotonic but no trade names are available.
Question:For What is hypertonic and how is it different from hypotonic? would this be right, Hypertonic is when there is more salt solution than water in the environment, and there is more water solution in the cell. So the water comes out of the cell trying to balance the concentrations, but it will end up that the cell will shrivel. This would be an example of a cell that is in a hypertonic solution. Hypotonic is when there is more salt solution in the cell than water, and there is more water solution in the environment. So trying to balance the concentrations, water will be given into the cell, but the cell will end up bursting.
Answers:Hypertonic solution is one of two solutions that has a higher concentration of a solute.
Hypotonic solution is one of two solutions that has a lower concentration of a solute.
Hypertonic solution: A solution with a higher salt concentration than in normal cells of the body and the blood. As opposed to an isotonic solution or a hypotonic solution.
Hypotonic solution: A solution with a lower salt concentration than in normal cells of the body and the blood. As opposed to an isotonic solution or a hypertonic solution
Question:Does the rate of osmosis of a cell immersed in a hypertonic solution continue to increase if temperature rises, say, above 100 C? Or can the the temperature get too hot? Is there a maximum temperature? If there is one, what happens to the cell and osmosis when it reaches its maximum?
Answers:the temperature will affect enzyme controlled reactions in teh cell, but water can move in and out freely. so as the temperature continues to increase sp will the rate of osmosis (untill an equilibrium is reached)
Question:Results of Lab: The iodine turns the starch and water mixture in the cub purple. The iodine doesn't not turn the water in the cup black, but after a while the contents of the plastic bag turn black.
Answers:Generally hypotonic means having a lower concentration of solute(s) than the standard solution. In contrast, hypertonic means having a higher concentration of solute(s) than the standard solution. The standard solution is usually the human body, particularly human blood. If the standard solution is distilled water, then both the starch and the iodine solutions will be hypertonic. If osmotic pressure tends to cause liquid to diffuse into the solution, then it is hypertonic. If liquid flows out of the solution, making the bag grow smaller, then it is hypotonic.
I would guess that both of your solutions are hypertonic, but there is not enough information to answer for certain.
Isotonic Solution, Hypertonic Solution, Hypotonic Solution. :Tonicity experiment : Red Blood Cells subjected to Isotonic, Hypertonic and Hypotonic solutions. Video captured at x400 magnification. Hypotonicity video is of the highest quality I have seen as a perfect salinity was found after many trials to produce a slow, real time haemolysis. Many thanks to our resident IT expert and lecturer at ACU National: Majella Hales for her expert software/editing assistance.
Red Blood Cells in a Hypertonic Solution :Red blood cells are suspended in a 0.85% Saline solution. 1.75% NaCl solution is added slowly, and cells that are fixed in place slowly lose the water within their cell membranes. Note the appearance that the cell is withdrawing from the environment, or shrinking/becoming dehydrated when the hypertonic solution is added.
