Potato Lab Background information: A hypertonic solution is a concentration that is higher than the solution. A Hypotonic solution is a concentration that is lower than the solution. An isotonic solution is a concentration and solution that is the same amount. Hypothesis question: What will happen if you put a potato in hypertonic solution? What will happen if you put a potato in hypotonic solution? What will happen if you put a potato in isotonic solution? Hypothesis statement: If you

In solution hypotonic to the sheep’s red blood cells‚ the red blood cells will lyse‚ as a result of the water entering the cell via osmosis. First‚ a stock solution of NaCl was prepared at concentration 1.0M. Working solutions were made ranging from hypotonic to hypertonic with a negative control at isotonic solution (150mM). The solutions were diluted up to 4 mL into 5 test tubes‚ (0mM‚ 0.13mM‚ 0.15mM‚ 0.17mM‚ 0.3mM 0.5mM) using distilled water to dilute the stock solution. The working solutions

different situations: hypertonic solution‚ isotonic solution‚ and a hypotonic solution. A hypertonic solution is when there is a higher concentration of salts dissolved outside the cell and pure water inside the cell‚ the water rushes out of the cell to try to dilute the salt solution causing the cell to shrivel up. An isotonic solution is where the water has achieved equilibrium with concentrations inside and outside of the cell‚ so there is no alteration of the cell. A hypotonic solution is where there

Aquarius(Sports Drink) Background Aquarius is a new isotonic sports drink launched in Asia at the year 2012 by The Coca-Cola Company. Aquarius was introduced in Japan in year 1983 as a grapefruit flavored sports drink as a response to compete for market share with other isotonic sports drinks such as Pocari Sweat‚H2O and 100plus.Aquarius was also the official sports drink for Olympics game in Barcelona in 1992 and 2012.As it’s a new launch product in Asia‚ there’s a need to create awareness to

Lab #3: Isotonic contraction and the effect of load on skeletal muscles Abstract The job of the motor nervous system is to control certain elements in muscles simultaneously to ultimately produce movement. Movement of the body is the result of specialized cells directly associated with skeletal muscle. Skeletal muscles are voluntary muscle and must contract before movement can occur. We know the muscle team moving the arm is formed at the biceps and triceps. Biceps can bend the elbow‚ but

Investigating the Difference in Isotonic Point in Sweet and White Potato Research Aim: To observe whether equal sized white potato or sweet potato cores reached the isotonic point in the same concentration of sucrose solution. Introduction: Osmosis is diffusion of water from areas of high water potential to areas of low water potential. It does not require an input of energy. Plants use osmosis to transport minerals from their roots to their leaves‚ and to take in water in the soil. Because the

I have been asked to investigate the effects of osmosis on potato cell sap. I will test potato cylinders in different strengths of sucrose solution and record any results in a table. I will then analyse my findings and work out the isotonic point of the potato cell sap. Prediction I have looked at my scientific knowledge from the background theory I carried out and I will base my prediction upon this information. In this experiment‚ I expect the different concentrations to show fairly noticeable

an area with less concentration. A Hypertonic Solution is a solution of a higher concentration of solutes and a smaller concentration of water molecules than another solution. However‚ an Isotonic Solution is a solution that contains an equal concentration of solutes and of water molecules‚ the same as another solution. A solution that contains a lower concentration of solutes and a higher concentration of water molecules than another solution is called a Hypotonic Solution. A cell that has a Selectively
