P4: to describe two theories of ageing –disengagement and activity P5 – Describe physical and psychological changes due to the ageing process M3: Use examples to describe the 2 theories of ageing D2: Evaluate the influence of 2 major theories on health and social care provisions. The activity theory The Activity Theory was originally an idea that was proposed by Lemon Bengtson &Peterson this proposal was seen to have a much more hopeful and positive view on ageing in comparison to the

amount of sucrose concentrations. The higher molarity concentrations increased the movement of water to balance out the inside of the tube and the beaker. The greater amount of concentration gradient‚ in each tube‚ increased the rate of osmosis. This rate of osmosis is due to the net movement of water from an area of low concentration to an area of high concentration. Because the tubes had different concentrations‚ certain tubes gained more mass than others. Solution A had 0.6 molarity which increased

keep undesirable substances out‚ hence‚ making it selectively permeable. One method of transport is called active transport‚ which uses ATP to transport substances through the membrane. The other is called passive process‚ which does not require ATP energy and the transport process is driven by concentration or pressure differences between the interior and exterior of the cell. All molecules are in constant motion‚ ergo‚ possessing kinetic energy. This kinetic energy is the motivating force in

As discussed in the intro‚ the purpose of this lab is to observe principles of homeostasis and osmosis in action. The results of this experiment showed that eggs placed in a 4 M sucrose solution lost mass over time and had the greatest percent difference in mass compared to the eggs in other solutions‚ with the 4 M egg having an average of -25.13% difference in mass. The 0.0 M solution egg only had a 12.28 average percent difference in mass‚ the 0.5 M egg with 10.39%‚ and the 1 M egg with the least

Osmosis Lab Conclusion The purpose of this lab is to determine whether salt affects the movement of water in the cell. Independent variable is the factor that affects the value of variables dependent to it. In osmosis lab‚ the independent variables are the potato and onions. The dependent variable is the variable whose value is measured to determine the extent of the effect of another variable to it‚ as in an experiment. In osmosis lab‚ the dependent variable is the length of the potato. The controlled

Lab Report on Osmosis and Diffusion Biology 1‚ Period 3 March 15‚ 2010 Lab Team: Jason Perez‚ Kicia Long‚ Chris McLemore Purpose: The purpose of this lab is to observe the acts of passive transport: diffusion and osmosis in a model membrane system. The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration. The model membrane is dialysis tubing. Materials Used 2.5 cm dialysis tubing 15% glucose

In your own words‚ describe the overall goal of the storyboarding activity. The storyboarding was to demonstrate of how a muscle contracts and how it goes back to relaxation‚ but more importantly how each part does it function for this to happen. I was a little confuse about how the process happens‚ but I’m the type of person that can learn more when I have a visual so I think it was really helpful to to do the storyboarding. In today’s labs I learned how the channels open and releases and let in

The Process of the Criminal Justice Process Ticauda Coleman Strayer University Dr. Denise DeShields January 13‚ 2013 The topic that I chose to describe is the criminal justice process. The criminal justice process is described as a process that involves a series of steps beginning with the investigation of the crime and the arrest of the suspect. The next step following the investigation is the pretrial activities‚ which include the first appearance‚ a preliminary hearing‚ information or

Diffusion and Osmosis Shown In Solutions Section 1: Abstract This lab‚ title Diffusion and Osmosis‚ was centered around the diffusion across a cellular membrane and how exactly materials move and diffuse in concentrations. Both diffusion and osmosis are forms of movement that are part of passive transport dealing with cell membranes. Diffusion is where the solutes move from an area of high concentration to a low concentration. Water goes through the cell membranes by diffusion. Osmosis is specifically
