Yeung Bio 101 Cyrus MacFoy June 16‚2015 Diffusion and Osmosis Exercise I. Molecules are always in constant movement. Molecular motion is a form of energy‚ the kinetic energy of molecules. The Brownian movement is the movement of small particles caused by the bombardment of the particles by millions of water molecule. This movement will continue indefinitely as long as there is water. My prediction for this lab is the solution of the water is hypertonic meaning there is a higher concentration of

Lab Report on Osmosis and Diffusion Biology 1‚ Period 3 March 15‚ 2010 Lab Team: Jason Perez‚ Kicia Long‚ Chris McLemore Purpose: The purpose of this lab is to observe the acts of passive transport: diffusion and osmosis in a model membrane system. The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration. The model membrane is dialysis tubing. Materials Used 2.5 cm dialysis tubing 15% glucose

wondered how much sugar it takes to overflow a mug in different water temperatures. I thought it would be cool to find out so i did an experiment. I used five diffferent temperatures of water 1.) cold tap water 2.) refrigirater water 3.)freezer water 4.) hot tap water and 5.) boiling water. I filled up a 2 cup mug with 1 3/4 cups of each type of water and added sugar until the mug overflowed. Purpose: I chose this experiment because I thought it would be fun to find out how much sugar was needed to

The Sugar Glider‚ also commonly known as the Sugar bear or Honey Glider ‚ refers to the Australian marsupial mammal that is a part of the Pertauridae family. The Glider’s scientific name Petaurus breviceps is Latin and translates into ‘short-headed rope dancer’ describing the animal’s 15-21cm length and 95-160g body covered in light blue-grey fur with a white underside. It is naturally found in Northern and Eastern Australia‚ sections of midland Australia‚ Tasmania‚ Papua New Guinea‚ Indonesia

Osmosis Lab Conclusion The purpose of this lab is to determine whether salt affects the movement of water in the cell. Independent variable is the factor that affects the value of variables dependent to it. In osmosis lab‚ the independent variables are the potato and onions. The dependent variable is the variable whose value is measured to determine the extent of the effect of another variable to it‚ as in an experiment. In osmosis lab‚ the dependent variable is the length of the potato. The controlled

loss or obtains. All the tubes contained different amount of sucrose concentrations. The higher molarity concentrations increased the movement of water to balance out the inside of the tube and the beaker. The greater amount of concentration gradient‚ in each tube‚ increased the rate of osmosis. This rate of osmosis is due to the net movement of water from an area of low concentration to an area of high concentration. Because the tubes had different concentrations‚ certain tubes gained more mass

2.3. Membranes and modules for forward osmosis: 2.3.1. FO Membranes Generally‚ any dense‚ non-porous‚ selectively permeable material can be used as a membrane for FO. Such membranes have been tested (in flat sheet and capillary configurations) in the past for various applications of FO. In early studies‚ the researchers applied various FO membrane materials‚ including bladders of pigs‚ cattle‚ and fish; collodion (nitrocellulose); rubber; porcelain; and goldbeaters’ skin [36]. By 1960‚ Loeb and
