    Lab # 2 Diffusion & Osmosis Introduction Kinetic energy‚ a root of energy stored in cells‚ causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water

    Brownian motion  This is‚ presumably the random drifting of particles suspended in a fluid (a liquid or a gas) .This movement was discovered and later named after botanist Robert Brown (1773-1858). He was a Scottish botanist and palaeobotanist who made important contributions (including Brownian motion) to botany largely through his pioneering use of the microscope. The scientist who made Brownian motion famous is Albert Einstein‚ who brought the phenomenon to the attention of the larger physics community

    surroundings‚ it tries to make concentration of solution inside and outside itself equal. However‚ the solutes are too big to pass the cell membranes without the help of channel proteins‚ or transport proteins. Water may freely pass through the membrane by osmosis‚ which requires no energy. Thus‚ the cell starts to take in‚ or release‚ water until it is isotionic to its

    Osmosis is the diffusion of water molecules from an area of high concentration of sucrose solution to an area of lower concentration of sucrose solution‚ through a selectively permeable membrane. The water molecules move down a concentration gradient in osmosis. Two diagrams of osmosis are shown in figures 1 and 2. Figure 1 shows the diffusion of water molecules through a selectively permeable membrane from an area of highly concentrated sucrose solution to an area of lower concentrated sucrose solution

    of different concentrations of saline solution on Red Blood Cells. When a Red Blood Cell is submersed in a high concentration of saline solution it will create a hypertonic environment and therefore cause the cell to rupture due to the process of osmosis. The methods used to collect data were observation and note taking. Overall the results proved the hypothesis correct with major findings being a higher concentration of salt causing a hypotonic environment and a low concentration. Recommendations

    currently looking at the nation’s consumption of chicken. Data have been gathered dating back to 1970‚ in hopes of finding variables that are closely correlated with chicken consumption so that the consumption can be predicted. In the spreadsheet you will find 36 observations…one for each year since 1970. The variables are: Year = Year Y = per capita consumption of chicken (lbs.) X1 = Real disposable income per capita ($) X2 = Real retail price of chicken per lb (cents) X3 = Real retail price of

    Shell - less egg is placed into a beaker of corn syrup‚ will there be any water going into or out of the egg and if the shell - less egg is placed in a beaker of distilled water will be any net flow of water going into or out of the egg. Hypothesis: If a shell - less egg is placed into a beaker of corn syrup solution‚ then there will be a net flow of water going into the egg because the water molecules will be small enough to pass through the membrane of the egg. If a shell - less egg is placed

    Introduction: Diffusion and osmosis are passive processes of transport. Passive transport involves no disbursement of energy by the cell. Diffusion movement is from high concentration to low concentration‚ which the driving force for this type of movement is kinetic energy particles themselves. Which crystal (Methylene blue‚ solid or Potassium Permanganate KMnO4-purple) will move further than the other due to the driving force (kinetic energy)? My prediction is that Potassium Permanganate KMnO4-

    Joanna Packham ENG 111 Reverse Osmosis in Our Life My husband and I installed a reverse osmosis drinking water system in our home. I have traveled a lot recently and met lots of people including engineers on the yachts that thought me a lot abut reverse osmosis systems. They explained to me that RO are declining in popularity because they remove the minerals as well the impurities from the water. Long-term consumption of filtered water had negative health effects. I was asking myself is RO water
