The Crusades were serious vicious Holy wars between the Christian states or Europe and Saracens ‚ who are present day Muslims. There were a total of nine crusades ‚ the first four being the most notable and the Children’s Crusade being the decline of the conflict. The crusades started in 109A.D around the sacred city of Jerusalem which held significant religious value to both the Christians and Muslims. The Children’s Crusade as initiated because of young peasants in France ‚Germany that were to

Osmosis is the diffusion of a solvent across a selectively permeable membrane that occurs in response to differences in solute concentrations (Allen and Harper 2014).Osmosis can fall under the category of passive transport which does not require energy. With osmosis being a type of diffusion it is viewed as molecules moving from a high concentration to a low concentration. To further explain if there is a low water concentration‚ high amounts of solutes will be present. Water will most likely move

In the First Crusade‚ Christian knights that came from Europe went and capture Jerusalem. They had been massacring almost all the city’s Muslim and Jewish population. The reason this happened was because Christians were being persecuted in Jerusalem‚ because the Holy City was passed from Egyptians to Seljuk. A Pope called for a crusade to help Christians in the east and to recover the holy lands. And then people went over there immediately. A Crusade called “People’s Crusade” had went a far way with

Describe two variables that affect the rate of diffusion. Size of material and concentration 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? The molecules were too large to pass through. This is what I predicted

The First Crusade (1096–1099) was a military expedition by Roman Catholic Europe to regain the Holy Lands taken in the Muslim conquests of the Levant (632–661)‚ ultimately resulting in the recapture of Jerusalem in 1099. It was launched on 27 November 1095 by Pope Urban II with the primary goal of responding to an appeal from Byzantine Emperor Alexios I Komnenos‚ who requested that western volunteers come to his aid and help to repel the invading Seljuq Turks from Anatolia. An additional goal soon

Diffusion Experiment: Osmosis in Sucrose Solutions Abstract We used dialysis tubing to simulate a semi-permeable membrane. Since molecules diffuse from their higher concentration to their lower concentration‚ water will move across the membrane in response to this concentration. While conducting this lab we were able to observe passive transport through diffusion and osmosis. Introduction Osmosis is a specialized case of diffusion that involves the passive transport of water. When

DIFFUSION AND OSMOSIS: WHAT’S TO EXPECT? Diffusion and osmosis are very important in biological process. Diffusion is the movement of molecules or ions from a region of their high concentration to a region of their low concentration. Osmosis is the diffusion of water molecules across a semipermeable membrane. To gain a better understanding of diffusion and osmosis‚ we examine multiple experiments to show diffusion and osmosis in animal cell‚ plant cell and synthetic cell. In our first experiment

Diffusion Through Membranes IB Biology 11 Diffusion Through Membranes OBJECTIVES In this experiment‚ you will Use a Conductivity Probe to measure the ionic concentration of various solutions. Study the effect of concentration gradients on the rate of diffusion. Determine if the diffusion rate for a molecule is affected by the presence of a second molecule. BACKGROUND Diffusion is a process that allows ions or molecules

Simple diffusion The term simple diffusion refers to a process whereby a substance passes through a membrane without the aid of an intermediary such as a integral membrane protein. The force that drives the substance from one side of the membrane to the other is the force of diffusion. In order for substances to pass through a cell membrane by simple diffusion it must penetrate the hydrophobic core of the phospholipid bilayer. The types of molecules that can do this are themselves substantially

Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. With diffusion no energy is required and it is caused by kinetic energy. The rate of diffusion can be affected by many things including temperature‚ molecular weight‚ and movement. To test the rate of diffusion a drop of dark food coloring was added to a glass of tap water and it was timed to see how long it took for the drop to reach the bottom of the glass. This procedure was repeated three
