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

REVIEW SHEET‚ EXAM 3 Chapter 6‚ Nutrition and Microbial Growth Define the four major modes of nutrition in microorganisms and distinguish among them in terms of energy and carbon sources The four major modes of nutrition are: 1. Photoautotrophs: (ex. Plants‚ some protozoa‚ & alegae) -microorganism which use carbon dioxide as a carbon source and light energy from the environment to make their own food. 2. Chemoautotrophs: -microorganism which uses carbon dioxide as a carbon source and

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
