Osmosis

Analyzing Osmosis in Gummy Bears Stephania Turyk and Anastasija Racic March 2016 Pre Lab Questions Why is it so important not to eat or drink anything in the lab? It is important not to eat or drink in the lab because the lab may be full of many contaminations that may enter your food or drink causing you to be very ill. Describe the direction of the flow of water when plant cells are placed in a hypertonic solution. When a plant cell is…

its reduction in volume. The Pressure in the bag reduces due to a loss of volume of the solvent. A point reaches whereby the pressure on the outwards side of the tubing equal to the force driving the water out of the tube. At this point, no more osmosis occurs in the bag (Wisniak, 2013). Bag B stimulates a cell whose contents are isotonic to its surrounding environment. This situation arises because the concentration of the bag contents is 1% sucrose concentration that resembles the solute…

diffusion process quickens because the molecules have much more contact, resulting in an even spread. 1b. What other variables might influence the rate and direction of osmosis? The properties of the cell and its selectively permeable membrane, the solute, and the surrounding environment could influence the rate and direction of osmosis. 1c. How would diffusion of a starch be different from a protein? Diffusion of a starch would be slower because of the larger particles but it travels…

Osmosis is the movement of a solvent, water, through the cellular membrane. Salt triggers osmosis by attracting water and causing it to travel across the membrane. When new salt is introduced in the substrate there is a higher amount of salt concentration on the outside of the cellular membrane. This…

It is not as energy intensive as reverse osmosis, it allows for heavy chemical to be collected throughout the evaporation so there isn't as much pollution, and we have a large source of sea water and it might motivate us to clean up our coastal areas more. There would also be less cost in transporting…

Introduction: Galaxiids are freshwater fish belonging to the galxiidae family. There are migratory and non-migratory species found in New Zealand. The migratory galaxiid fish that are native to New Zealand, are the Giant kōkopu (Galaxias argenteus), short-jaw kōkopu (Galaxias postvectis) and the banded kōkopu (Galaxias fasciatus) (DOC, 2010). Galaxiids generally breed in Autumn and their breeding and migratory patterns differ depending on the species (DOC, 2010). The adults of kōkopu species…

An ELL student is described as a linguistically and culturally diverse student who is learning the English language in addition to his or her native language. In my current fieldwork experience and to the best of my knowledge, there are no ELLs students attending any of the classes that I currently observe. From what I’ve observed, the classes I attend are not highly diversified by ELL’s, those students who are, seem to speak English fluently with no noticeable difficulty. Therefore, I am unable…

into the blood by osmosis. Reabsorption of water in the loop of Henle and collecting duct: The loop of Henle is a hairpin loop that runs deep into the medulla and then turns and goes back to the cortex again. The function of the loop of Henle is to create an area of high solute concentration deep in the medulla. The collecting duct of each nephron pass through this area and so a lot of water can be reabsorbed from the collecting ducts by osmosis. Concentrated…

solute form higher or lower concentration in order to be balanced, facilitated diffusion which is when molecules are moved through special transport molecules within the membrane, filtration the movement of water and solute through the membrane, and osmosis which transports water molecules. An act of cell recognition is organisms with multiple cells have the to ability to allow cells into the the membrane that belong, and disallow cells that are foreign this process is known as the immune…

The process can take place in three parts. • Filtration – This process happens in the entire nephron system. When blood goes through and into the capillary at the beginning of the nephron, small molecules, such as glucose, urea, ions and water are cleaned out and passed through the nephron tubule. The larger molecules such as blood proteins, cannot fit through the capillary wall as they are too big, therefore they stay in the bloodstream. • Reabsorption – When the small molecules are cleaned…
