    movement. Find the direction and the rate of diffusion of their molecules of different sizes. Determine the direction and the rate of osmosis in and out of simulated cells in hypotonic, hypertonic and isotonic environments. Final purpose of this experiment is to find hypotonic, hypertonic and isotonic solution in a blood cell and hypertonic in a plant cell. To see how they affect the volume and the integrity of the…

    hypotonic animal cell expand and burst. A hypertonic animal cell will undergo osmosis and release water eventually causing the cell to shrivel up and shrink. Both of these results make it extremely important for animal cells to reach equilibrium or isotonic levels. Place 4 full pipettes of starch into a small beaker. Use a pipette to add 4 pipettes of α-amylase to the small beaker then stir. Open dialysis tubing from one end then tie the tubing with a clamp. Open the moist end and add 4 pipettes…

    Discussion: Based off the results from this lab the student was able to determine whether the model cell and cell environment each represent a hypertonic, hypotonic or isotonic solution. The first solution cell and environment the student had, was water and sodium chloride. In this instance water was the model cell (what was in the dialysis tubing) and Sodium chloride was the surround environment (plastic cup). The initial weight of the model cell was 13.2g, but after sitting in the sodium…

    water visible. As stated there will be three solutions, this will help answer the question of how each type of solution will individually affect the egg when left intact overnight. This will classify each solution into a hypertonic, hypotonic, or an isotonic solution. The egg would first encounter a vinegar solution. If the egg is placed in 150 mL of vinegar and left intact overnight then, it would…

    Acid-Base Case study 1 The acid base balance of the body is mainly regulated by respiratory and renal system together with the body ‘buffer system. For the body to function normally, the hydrogen ion (H+) needs to be concentrated within a narrow range, represented as pH, which determines the acidity and alkalinity of a solution. Changes in the bicarbonate (HCO3) concentration causes metabolic acidosis or metabolic alkalosis while changes in the rate of alveolar ventilation and carbon dioxide…

    if needed. The patients vital sign, oxygen saturation, urine output should be closely monitored. After taking the history a quick and through physical examination should be performed. IV access in one or both unaffected limb should be established. Isotonic saline should be initiated as fluid resuscitation if there is any evidence of hemodynamic instability. If it’s possible the snake should be identified. The required investigation should be done and features of systemic or local envenoming…

    increase the entropy. Water is solvent so water move from low concentration to high concentration is called osmosis, that is hypotonic, but the water move from high to low is hypertonic solution. And if the water stands equal inside and outside it is isotonic solution. Hypertonic solution has less than hypertonic solution.…

    In the first part of the lab we were able to study the diffusion of various carbohydrates and the osmosis of water. Diffusion is the process of small molecules moving through a semipermeable membrane while osmosis of water is the movement of water through a semipermeable membrane from an area of high water potential (low solute potential) to an area of low water potential (high solute potential). Both diffusion and osmosis move in the direction that would create equilibrium on both sides of the…

    Osmosis in Deshelled Chicken Eggs Brooke Sandy Partners: Alexa Smarra, David Egesigh, and Yousef Bahliawah Abstract Throughout the process of this experiment, chicken eggs were used to test how well certain solutions would be absorbed. The objective was to determine the rate and direction of osmosis into and out of cells according to their diffusion gradients. During this experiment eggs were rolled on paper towels to blot the excess liquid and then weighed. They were then placed into one of…

    Isotonic contraction causes body parts to move by lengthening or shortening the muscles. Muscles within the body shorten through concentric contraction. This type of contraction is the most common and occurs during daily activities. An example of this is…
