For each article‚ answer the following questions: 1. What is/ are the Objective/s of the Study? The objectives of this study were first to describe the level of disability‚ physical impairment‚ and rate of return to work for compensated workers before and after the completion of a physical therapy program with multiple interventions and second to evaluate the influence of compliance‚ chronicity‚ and pain distribution on the level of disability‚ impairment‚ and work status. 2. Identify and discuss

across a selectively permeable membrane involves a special form of diffusion called osmosis. When the external and internal solute concentration are equal‚ there is no movement of water will be observed. This is described as isotonic. Osmosis does not occur in an isotonic solution‚ because the concentrations are equal on both sides of the membrane and there is no net movement of molecules from one side of the membrane to the other (Payne‚ 2007). A hypotonic solution is a solution in which the

The volleyball spike is a process in which the athlete uses their lower extremities to generate ground reaction forces that lead to a vertical jump. The trunk and core are used to maintain balance and stability of the body while the athlete is in mid air. The upper extremities are then used to make initial contact with the ball‚ ultimately sending it over the net onto the other side of the court. There are approximately four phases to a volleyball spike: The run up/attack phase‚ the take off phase

Discussion: Osmosis is a passive process by which water molecules move through a partially permeable membrane from a region of high concentration to a region of low concentration‚ creating an equal amount of molecules from both regions on each side of the membrane. This process is the result of a downhill energy system known as water potential. Water potential is the potential energy of water (per unit volume) that allows it to move from one area to another by osmosis. This system causes the water

Rate of Osmosis vs Solute Concentration Introduction: In nature‚ the quest to reach equilibrium‚ or the state of rest or balance due to the equal action of opposing forces (http://www.dictionary.com). Osmosis and diffusion are two ways that cells reach this equilibrium‚ without exerting energy. Due to the unique nature of the phospholipid bilayer‚ small molecules can pass through the semipermeable membrane easily‚ through diffusion (https://www.biologycorner.com). Water‚ however‚ has a slightly more

molecules‚ but not solute. The main principle of osmosis is to equalize the concentration of solute between the cells and their environment (Kent 2000). Generally‚ there are three different conditions‚ when the solution is isotonic‚ hypertonic or hypotonic to the cell. In isotonic solution‚ when water potential inside and outside the cell is equal‚ both animal and plant cell behave in the same way: there is no net movement of water. In hypertonic solution‚ when water potential of the cell is higher

store water for later purposes. It doesn’t burst like animal cells because plant cells have a cell wall which is there for extra protection and in this case‚ it keeps the plant cell safe from bursting. The last kind of solution is called isotonic. In an isotonic situation‚ solutions have an equal concentration of solute due to water diffusing at

the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating that the net movement of water moves into the said solution whereas a hypertonic solution is one with a higher osmotic pressure‚ thus the net movement of water will be leaving the hypertonic solution. Lastly‚ an isotonic solution entails no net movement of water across a semi-permeable membrane as the two substances
