Isotonic

In conclusion, I learned from this experiment that animal cells, similar to the egg, must be placed in the isotonic environment in order to function properly since it has equal amounts of solute and water concentration inside and outside the cell which causes no net movement for the diffusion of water from high to low…

When the egg was placed into syrup, a hypertonic solution, it shrunk in size. This result supports my hypothesis. The mass of the egg before it was placed in syrup and after it was placed in syrup changed drastically. There was a 16 g decrease in mass that happened to the egg during its time in the syrup. Both the long and short circumference of the egg decreased. The long circumference before the egg was placed in syrup was 18.75 cm and after it was taken out of the syrup the long circumference…

minimize contact with the sun to prevent water loss. Some examples of this are no leaves and deeper roots on plants. A protist may do the same thing, simply to a lesser extent. This is because the protist does not have a cell wall and would prefer an isotonic environment rather than a hypotonic…

The purpose of this EEI is to create and analyse an experiment that relates to and supports the theory of osmosis in biological cells. Cells are the biological building block for all life; all living organisms have cells also. Cells provide structure, absorb nutrients from food and convert those nutrients into energy so that the cell can carry out specialized functions. There are two main categories with most organisms and their cells; prokaryotes and eukaryotes. The distinctive difference…

I. Introduction: Osmosis is a mode of passive transport used by the cells. It involves the transport of a solvent like water across a semi-permeable membrane. Osmosis is the movement of solvent molecules from an area of low solute to an area of high solute. In osmosis, the semi-permeable membrane (the lipid bilayer) enables the solvent molecules to pass freely between but limits movements of the solute. Osmosis is the primary way water moves into and out of all cells. In this experiment, the…

Physical therapy is a vital part of a successful surgery but patient compliance is essential.9 After surgery, the physical therapy will progress in four phases.9-10 Initially, the repair and tendon need to be protected.9-10 This generally involves immobilizing the joint in a sling for 4-6 weeks after surgery.9-10 The length of time the joint is immobilized depends on what type of surgery was performed. 9-10 During phase I the patient will be introduced to prophylactic active motion at the elbow,…

It is expected that if the concentration of sucrose increases from 0.0 M, 0.2 M, 0.4 M, 0.6 M and 0.8 M (±0.01 g) in a 40 (±0.5) mL sucrose solution, then the average percent change in mass in Solanum tuberosum core will decrease. This is because if the Solanum tuberosum cores are placed in a hypotonic sucrose solution, which is described as having lower osmolarity, than the percent change in mass of the Solanum tuberosum core will increase due to the fact that water molecules will be moving…

Each bar in the graph represents a different solution of urine. The control sample is 4.5g of salt per liter of liquid. This makes it an isotonic solution. This solution is most like what the urine in an infant should be. The average amount of liquid that a diaper could hold for the isotonic or control solution was 246.1 mL. The solute medium solution was a hypotonic solution. This solution had 1g of salt per liter of liquid. This solution represents an infant that…

tonicity. Tonicity is the tension in the fluid, which is due to the concentration of dissolved solutes within it. Furthermore, osmosis has three different types of solutions called isotonic, hypertonic, and hypotonic. osmosis has three different types of solutions called isotonic, hypertonic, and hypotonic. An isotonic solution is when the concentration of substances is the same in and out of the cell. Even though it’s the same, the movement of molecules through the membrane still occurs. The…

Functional ankle instability has been described as having continuing episodes of the ankle giving way, weakness, and general disability. This is usually caused by deficits in strength, proprioception, and functional performance; which is why often rehabilitation is based on improving these. Often what causes these deficits is the result of having multiple ankle sprains. The article is a randomized control trial aimed at “comparing the effects of resistance-bands (RBP) and proprioceptive…
