    Analyzing Various Permeable Bags Placed in Different Concentrations of Water and Sucrose Introduction Osmosis is defined as the movement of water from a region of water that has a higher potential to a region of water that has a lower potential through semipermeable membranes. There are three types of solutions, hypertonic, hypotonic, and isotonic. Hypertonic solutions have a higher concentration of solute while hypotonic solutions have a lower concentration of solute. Isotonic solutions have an equal concentration of solute. There is no net movement going in or going out of the isotonic solution or solute. The purpose of this experiment is demonstrate osmosis by weighing the dialysis bag to indicate whether or not the bag is hypotonic, hypertonic or isotonic in the different concentrations of water and sucrose. By carrying out this experiment we will be able to better understand how the process of diffusion and osmosis works. My hypothesis is that diffusion will continue to occur throughout these various mixture of concentrations in the dialysis bags until equilibrium is reached. Once equilibrium is reached there should not be any net movement. Therefore, I predict that the bag with the higher concentration of sucrose will turn out to be hypertonic and while the lower levels of dialysis bags with sucrose will…

    The one repetition maximum test is a common method of measuring isotonic muscle strength. It is a rough measurement of the heaviest weight a participant can perform a clean lift. It is recommended that you should only warm up before as you will not want to risk injury but by doing too much your muscles would have already begun to fatigue. Then after a rest of at least several minutes, increase the weight and try again. The athletes chooses subsequent weights until they can only repeat one full…

    The three types of muscle contraction that will be discussed in this report are isotonic, isometric and isokinetic contraction. Isometric contraction is also known as static contraction and provides the most benefits to immobilized individuals who are currently in rehab due largely to the fact that it involves the strengthening of the muscle with apply force to the joint. Isometric contraction involves the muscle generating force however there is no change in the angle of the joint. As a result…

    The expected sodium versus actual sodium comparison in Figure 8, we saw that the actual sodium excretion of the control and hypotonic subject was greater than the expected sodium excretion, which was expected in the hypotonic subject due to the amount of fluid intake at the beginning of lab. The isotonic actual sodium excretion was a little below the expected sodium excretion due to the high fluid intake but low excretion of urine throughout the two-hour experiment. The alkalosis subject showed…

    We have over 600 muscles in our bodies that perform a variety of functions. All muscles are made of the same tissue but within our bodies there are 3 different kinds of muscles. There are Cardiac, smooth, and skeletal muscles and each of these is found in different places. Cardiac muscles are in the walls of the heart, Smooth muscles are in the walls of organs, and skeletal muscles are attached to our skeletons. Cardiac and smooth muscles are involuntary used whereas skeletal muscles are…

    Discussion The results of this experiment for the hypotonic treatment group did support the tested hypothesis that urine production rate should increase, while salt concentration and specific gravity of urine should decrease for this group. For the isotonic treatment group, the tested hypothesis was supported in that the specific gravity and salt concentration went up slightly, but was not supported in that the the urine production rate did not greatly increase over time. The findings for the…

    the bags with the different percentages of sucrose put into a beaker of water would have the water flowing into them, the bag with water that was put into a beaker of sucrose solution would have the water flowing out of it, and the bag with water that was put into a beaker of water would have an equal flowing of water. The hypothesis was correct for all three of its components. The rate of osmosis is different between hypotonic, hypertonic, and isotonic solutions because of the water that is…

    Abstract This lab was conducted in order to determine the molarity of sucrose concentration where the mass of 2cm^3 of Classic Russet potato segments and pear segments does not change, representing an isotonic concentration. By calculating the change of mass of the potato segment and pear segments prior to being placed in the sucrose solution against the mass after being in the sucrose solution for 45 minutes. Our goal was to determine what type of osmotic concentration was created as compared…

    throughout time. (Waller, 2010) Three type of progressive resistance exercises are commonly used, isotonic, Isometric, and Isokinetic. Isotonic exercise stimulates movement of a part of the body through a full range of motion (caused by the shortening and lengthening of muscles) via variable resistance from equipment. The resultant movement is not at a constant speed, but instead at a variable or changing speed. More simply put, isotonic exercises entail the conditioning of a group of muscles…

    be the cause of the symptoms or be a result from a disease process or treatment; intravenous fluid administration is one commonly used method for treating these electrolyte and fluid imbalances. Hypertonic fluids have a higher osmolality than body fluids; examples of hypertonic fluids include D5/0.9% saline, 3% saline, D5/0.45% saline, and D5/Lactated Ringers (Trakalo, 2015). The difference in pressure gradients pulls fluid out of the intracellular space to create more volume within the…
