Throughout this lab‚ diffusion and osmosis has been seen and tested through experiment. In part A of the lab‚ diffusion was demonstrated with two solids and an agar gel petri dish. One crystal of potassium permanganate and one crystal of methylene blue were placed on either side of an agar gel petri dish. The purpose of this experiment was to determine which of the crystals would diffuse across the gel more. So the question is‚ which solid would have a higher rate of diffusion through the agar‚ methylene

1 Background Diffusion is a process‚ in relation to the spontaneous movement of molecules from an area of high concentration‚ to an area of low concentration down a concentration gradient. It is a type of passive transport method‚ that requires no cellular energy (ATP). This movement occurs‚ until a state of equilibrium has been established on both sides of the membrane. The diffusion of molecules happens at cellular level‚ through a cell membrane via the pores. The cell membrane is a layer

This paper is my response to the literature by Frances Stokes Berry and William D. Berry titled “Innovation and Diffusion Models in Policy Research” as well as the article by Charles R. Shipan and Craig Volden called “The Mechanisms of Policy Diffusion”. In this essay‚ I maintain that the unified model proposed by Berry and

Osmosis and Diffusion During the past few weeks in my Ag Biology class we have been learning about and reviewing both osmosis and diffusion. We did two different labs‚ one on osmosis; the other on diffusion. The first lab we did was our diffusion lab. We learned that diffusion is moving something from an area of high concentration to a low concentration. We were showed that Mio and other flavor drops perform diffusion when put in water as an example. For the lab part we put a mixture of starch

---- 9 TITLE Osmotic pressure within red blood cell. INTRODUCTION Osmosis is a passive movement of water molecules going across the partially permeable membrane. It is a very spontaneous process due to the downhill energy flow known as “water potential” by which‚ water molecules move from a region of higher water potential to a region of lower water potential. Pure water has the highest water potential value which is zero ( = 0 ). This process occurs in cells‚ regardless of animals or plants
