The impact that the Crusades had on the Western world was that the Crusaders learn’t how to build better castle’s and more advanced war techniques. Another thing the Crusaders brought back to the western world was science and medicine‚ they also learn’t the arabic number system and made calculations a lot easier to do. They were also taught about were the Muslim world went to and in return taught them that the world was a lot bigger then what they thought it was. They had many different fruit‚ spices

Diffusion and Osmosis Lab Introduction • What molecules can pass through a semi-permeable membrane? In this lab study we tested carbohydrates such as starch and glucose‚ as well as solutions like Benedict’s and Lugol’s to see if they would cross the membrane of a cell but since we can’t actually see that happen we used dialysis tubing (acts as the cell membrane). • My prediction was that glucose and Benedict’s could pass the semi-permeable membrane but starch and Lugol’s wouldn’t be able to

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

Simple Diffusion Activity 1: Simulating Simple diffusion 1.What is the molecular weight of Na+? 22.9 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through? 50‚ 100‚ and 200 4. Which materials diffused from the left beaker to the right beaker? Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because the molecular weight exceeded the highest MWCO membrane‚ thus being to large to pass through

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 two types of passive transport. Diffusion is a random movement of molecules from an area of high concentration to an area of low concentration. Osmosis is a type of diffusion that diffuses water through a selectively permeable membrane. There were two parts to the experiment‚ the dialysis tubing lab and the potato lab. In the first experiment‚ the dialysis tubing acted as a semi-permeable membrane. A semi-permeable membrane is a membrane

The two statements are: 1- Crusades was a military expansion of Europe. 2- crusade were a disruption

and Diffusion Lab Report Background Information: Diffusion involves the movement of solute particles across a selectively permeable membrane from higher to lower concentrations. A selectively permeable membrane allows only some thing to go through. Water and oxygen are examples of molecules that are able to go through the membrane by diffusion. The
