The hypothesis if water is added to the cup then the mass and volume will decrease because water will go into the tubing to decrease solute concentration was supported by the data found in Table 1 and 2 because the cup holding the dialysis tubing with the protein solution’s mass decreased by 7.61 grams and the volume decreased by 17.3 milliliters while the mass of the cup with the tubing holding glucose solution also decreased by 1.19 grams and the volume decreased by 2.2 milliliters (Emma Ricks and

After the dialysis tubing soaked in the distilled water overnight‚ the measurements showed that the dialysis tubing increased in mass. The initial weight of the dialysis tubing was 19.08 grams‚ but it went up to 19.34 grams after sitting in the distilled water for some time. The amount of distilled water in the beaker also decreased. There used to be 200 mL of distilled water in the beaker‚ but it decreased to 199 mL after the dialysis tubing soaked in it. The data collected supports the claim that

Method: 1. From a prepared block of agar cut 5 cubes each at the following dimensions: -Side lengths of 10mm‚ 8mm‚ 6mm‚ 4mm‚ and 2mm. 2. Pour the 1M HCl solution into each of the beakers to a depth of 1.5 cm. 3. Place all pieces of agar into the solution at the same time and gently agitate while recording the time each takes to decolourise completely. 4. Record all raw data in the table you have prepared. Results: All organisms need to exchange substances such as food‚ waste

This could be blamed on technology. Robots have been a part of our world for many decades from numerous types of movies and shows. Now‚ instead of helping us they are taking jobs from thousands of people. For example‚ at grocery stores instead of going to a cashier at a register; anyone can

Using dialysis tubing to model diffusion of a cell membrane and investigating the influence of solute concentration on osmosis Purpose * Discover how dialysis tubing diffuses the cell membrane * Explore the effect of solute concentration on osmosis Background A cell membrane is a very significant function in the human body. In one sense‚ it is used as a barrier to keep the enzymes‚ DNA‚ and metabolic pathways that bundles everything together. Cell membranes are also used as a gateway

to the body’s blood flow‚ it can help monitor blood pressure and secrete hormones‚ which can raise blood pressure in the event when it does not receive enough blood flow. However the most important job is filtration of blood. The kidney works to filter out toxins‚ especially chemicals that are formed as a result of cells using energy. The kidneys also work to maintain the balance of electrolytes within the body which can be lost during exercise. Cells need a good balance of electrolytes such as sodium

There are many other possibilities that may happen during NDE’s‚ such as hallucination of seeing loved ones‚ a sense of being somewhere else in an unearthly place. The features of what NDE brings may lead to questions about afterlife. What happens if you walk towards the end of the light? Do you really see god? But all questions lead to the ultimate question of life; do NDE’s prove the existence of
