Serious case reviews (SCRs) The LSCB is the key statutory mechanism for agreeing how the relevant organisations in each local area will cooperate to safeguard and promote the welfare of children in that locality‚ and for ensuring the effectiveness of what they do. LSCBs carry out functions set out in regulations (LSCB Regulations 2006‚ S.I. 2006 no.90). Their work includes • agreeing local policies and procedures for how the different organisations will work together on safeguarding • contributing

We only had the potatoes in their solutions for 20 minutes instead of the normal 30 minutes which could mean that the potatoes did not go through the whole process of osmosis. Also‚ a lot of the experiment was rushed as we were under pressure to finish as quickly as possible. Unfortunately the time constraint was caused by and outside influence unrelated to the lab itself‚ and so next time we could do a lab under normal

BBC Learning English How to… Tell someone about a serious incident Neil: Hello‚ welcome to ‘How to…’ with me‚ Neil Edgeller. In this programme we’ll take a look at how to tell friends‚ or people you know quite well‚ about serious things which have happened to you. Perhaps you’ve been unlucky enough to have been attacked‚ or maybe you’ve seen something frightening‚ like a road accident. How do you introduce the topic to your friends? How do you tell the story‚ and how do you finish it

germination is the uptake of water by the seed. This is the part where osmosis takes place. Osmosis is the diffusion of water across a selectively permeable membrane in which the water moves from a high concentration to an area where there are water molecules with a low concentration. Osmosis is similar to diffusion in the way mentioned earlier with the molecules moving from high to low concentration. Another similarity that osmosis shares with diffusion is that both processes work as passive transports

In writing 1984‚ Orwell’s main goal was to warn of the serious danger totalitarianism poses to society. He goes to great lengths to demonstrate the terrifying degree of power and control a totalitarian regime can acquire and maintain. In such regimes‚ notions of personal rights and freedoms and individual thought are pulverized under the all-powerful hand of the government. Orwell was a Socialist and believed strongly in the potential for rebellion to advance society‚ yet too often he witnessed such

Osmosis Rates in Artificial Cells Daniel George Department of Biology Grand Valley State University 1 Campus Drive Allendale‚ MI 49401 georged@mail.gvsu.edu Abstract The lab for this paper was conducted for the topic of osmosis‚ the movement of water from high to low concentration. Five artificial cells were created‚ each being filled with different concentrated solutions of sucrose. These artificial cells were placed in hypertonic‚ hypotonic‚ or isotonic solutions for a period of 90

Biology GCSE Coursework: Osmosis in Potato Chips Skill Area P: Planning Aim: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Hypothesis: Osmosis is defined as the net movement of water or any other solution’s molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially

the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement of water across a selectively permeable membrane. In osmosis‚ water diffuses across the area of lower solute concentration to that of higher solute concentration until the solute concentrations of the environment and the cell are equal. Tonicity‚ which is the ability of a solution to gain or lose water due to osmosis‚ results in an environment that is isotonic‚ hypertonic‚ or hypotonic

Examining Diffusion and Osmosis Introduction: Purpose: 1. To simulate and observe the diffusion of solutes and the osmosis of water through a semipermeable membrane through color change and sugar tests. 2. To speculate osmosis occurring in dialysis bags and potato cores by comparing percentage change in masses. Background information: Molecules are always in random‚ constant movement due to their kinetic energy. This causes the molecules of a cell to move around and bump into each other

The results that were collected in lab #1 shows the relationship of surface areand volume in the artificial cells to the diffusion rate using the phenolphthalein-NaOH agar and the HCl solution. Lab #2 was a model of diffusion and osmosis‚ in which we filled the model cells with different solutions and determined the rate of diffusion. In lab #3‚ the results demonstrated the interactions between selectively permeable membranes‚ water‚ and solutes and how they are important in cellular and organismal
