The movement of water down its osmotic gradient across a selectively permeable membrane is known as osmosis. The difference in the concentrations of solutes on either side of the membrane results in the establishment of an osmotic pressure. Water follows the direction of solutes‚ this means that in the event where there are more solutes outside the cell than there are inside the cell‚ water will move from the inside of the cell to the outside in order to establish water balance. When a cell is placed

native religion‚ allowing it to be accepted in society and spread through monasteries and schools. However‚ they both did become incredibly popular and proliferate. There are multiple arguments that can be taken on to explain the differences in diffusion during this time period. Politically‚ Christianity posed a greater threat to the Jews than the Buddhists to the Hindus. Economics also played a role; Buddhism had the silk roads to travel and spread through. Religiously‚ Christianity and Buddhism

biology sbi4uo-a | Osmosis and Diffusion Lab | By: Elora Hobbin | | Group Members : Ashley Riley-Roy and Adam Reynolds | 9/11/2012 | | Introduction: Osmosis and diffusion are two procedures that are critical for cell survival. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. Osmosis is the movement of water molecules across a cell’s membrane. These two procedures help a cell to survive because they help maintain homestasis

Relationship Between the Rate of Diffusion and Molecular Weight as Observed in Postassium manganate‚ Potassium dichromate‚ and Methylene Blue Elisha Padilla Group 3 Sec. X – 8L March 26‚ 20151 ABSTRACT The relationship between the rate of diffusion and the molecular weight of a substance was determined by introducing three substances (KMnO₄‚ K₂Cr₂O₇‚ C₁₆H₁₈N₃SCl) of different molecular weight to agar-water gel‚ and measuring the distance of diffusion every three minutes

The Effect of Molecular Weight on the Rate of Diffusion of Potassium permanganate (KMNO4)‚ Potassium dichromate (K2Cr2O7) and Methylene blue ¹ ABSTRACT The effect of molecular weight on the rate of diffusion was determined using the Agar-water Gel Test. One drop of potassium permanganate (KMNO4)‚ potassium dichromate (K2Cr2O7) and methylene blue were used. Each substance has a respective molecular weight of 158 g/mol‚ 294g/mol and 374 g/mol. The diameters (in millimeter) were measured

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

Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration‚ in the direction that tends to equalize the solute concentrations on the two sides.[1][2][3] It may also be used to describe a physical process in which any solvent moves‚ without input of energy‚[4] across a semipermeable membrane (permeable to the solvent‚ but not the solute) separating two solutions of different concentrations.[5] Although osmosis does

DESIGN ASPECT 1: Defining the Problem and Selecting Variables CELLS are the basic unit of structure in all organisms and the smallest unit of life. All living things are made of cells. Multicellular organisms (humans) are composed of many cells. Unicellular organisms (bacteria) are composed of only one cell. Existing cells come from other pre-existing cells and cannot be created from non-living materials. All cells are surrounded with membrane called CELL MEMBRANE (PLASMA MEMBRANE). Plasma membrane
