mythelin blue affects the rate of diffusion through agar jelly. Hypothesis The diffusion of mythelin blue is directly proportional to its concentration‚ hence as the concentration increases; the rate of diffusion increases too. Controlled Variables Time time was kept constant while testing the diffusion spread of mythelin blue with each concentration. Temperature the experiment was undertaken in room temperature as change in temperature can affect the rate of diffusion‚ as a higher/lower temperature

taken to determine not only the cultural pieces that identify a society but also the environmental impacts that molded the society into what we know it as today. In the following paragraphs I will be explaining how the different environments of Mesopotamia and Egypt shaped their cultural traits. Mankind began as a hunter-gatherer species embracing a nomadic lifestyle based on the movements of prey and the lifecycles of plants. As man evolved he became more aware of the potential in domesticating

of dollars. Most of these resources‚ however‚ did not go into the theory of designing a bomb‚ as design was a relatively small part of the budget; rather‚ the money and manpower were needed to produce weapons-grade plutonium and uranium. Gaseous diffusion was‚ at the time‚ the most efficient way of separating the 235 U and 92 238 U isotopes.1 92 The question of why scientists entertained the idea of a uranium bomb at all is an intriguing one. Bohr had already demonstrated that uranium‚ when undergoing

The purpose of this lab was to observe how molarity concentration affects diffusion.The lab was primarily based on osmosis and diffusion. Diffusion is when the movement of molecules from a high concentration that go to a low concentration to a high concentration to eventually reach an equilibrium. Osmosis is when water will diffuse from high water concentration to low water concentration to reach equilibrium. When the solutions are different the lower concentration solute is hypotonic while the higher

permeable membrane through a process of diffusion. The movement of a solute through this membrane is called dialysis . Diffusion is a form of passive transport. It is the movement of molecules from areas of higher concentration to those of lower concentration‚ until there is an even concentration. This movement is random because it is a result of kinetic energy. Diffusion is a slow process‚ but there are many factors that will affect it’s rate. The rate of diffusion will vary depending on the size of

This article raised an interesting subject: surgeons and patients seeking improved treatment often forget that a new technique is not necessarily a better one. Human body with its health problems remains the same but the surgical technology is always moving towards progress. People develop new surgical tools and new surgical procedures constantly. However‚ do we carefully test all these new tools

Diffusion and Osmosis of Solutes and Water Across a Membrane Brittany Bacallao Nova Southeastern University Abstract: This experiment gave a visual understanding of osmosis and diffusion. The first experiment proved that solutes would move down a concentration gradient if permeable to the selective membrane. The second experiment proved different solute concentrations affect the movement of water‚ depending on the solute concentration inside the cell. The purpose of this lab was to look for
