Lab # 2 Diffusion & Osmosis Introduction Kinetic energy‚ a root of energy stored in cells‚ causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water
Premium Osmosis Chemistry Diffusion
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-

Where as the active transport requires energy from the molecule to be moved. oFacilitated diffusion can only move in one direction from high concentration to low concentration‚ which is with the gradient. Where the active transport can move from both low concentrations to high concentrations‚ therefore it can move against the gradient where as the facilitated diffusion can not. The process of active transportation is when a molecule work together with the active side of a protein

Introduction In Diffusion‚ Dialysis & Osmosis lab‚ we discovered that we were going to observe and understand the conditions under which diffusion‚ dialysis‚ and osmosis occur. Then we constructed models of diffusion‚ dialysis‚ and osmosis. We predicted that the direction of change would be from the membrane to the beaker. We understood how these processes affected the selectivity of the cell membrane. The second part of the lab was dealing with dialysis. In this part we studied starch and sodium

Experiment: At this experiment we are investigating does the temperature affect how quickly the particles diffuse to an even concentration throughout the water‚ we are going to do this experiment by using food coloring to see how quick the food coloring diffuse in hot water and cold water.

The Responsibility to Protect Introduction: Since the dawn of time there have been occurrences of massive violations of human rights. The 20th century in specific brought with it not only inter-state wars but also internal conflicts. However‚ in the last hundred years there has also been a substantial growth in international cooperation and solidarity. Through the creation of international organizations‚ such as the United Nations‚ and the growing number of non-governmental organizations‚ the
