The crusades were a series of religious battles fought in the 11th century between Christians and the Muslims. The third crusade‚ fought between Saladin and Richard the lion hearted between June7 and July 15‚ was critical for the Muslims. It was the third crusade which was fought between two very influential political leaders‚ Saladin Ayubi and Richard the lion hearted. Saladin led a series of expeditions to bring‚ Jerusalem‚ the third holiest city back under the Muslim control. This would allow

Diffusion of Innovations seeks to explain how innovations and social changes are taken up with a segmented group of people. Through knowledge and application of research-based theories‚ we have grown to understand the different perspectives involved in the evolution of change theories. During this time together‚

1 Diffusion is the movement of molecules (or ions) from a high concentration to low concentration. Diffusion is form of passive transport as energy does not need to be generated. Diffusion is complete when the concentration of molecules is equal on either side of the membrane. Diffusion rate can be influenced by many factors such as: Concentration gradient across the the membrane. Permeability of the membrane to the diffusing substance. Temperature. Surface area of the membrane. Question 2 2.1

Experiment 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

he mass and length of the potato piece must be kept the same in each experiment primarily because they affect the surface area of the piece‚ and varying surface area could have a great effect on the rate of osmosis. This is because in an experiment where the potato chip has a large surface area‚ there is a larger area of partially permeable membrane and therefore more opportunity for water particles to pass through. I will keep the surface area the same by keeping the mass and length

The Song of Roland depicts disregarding the actual history‚ Charlemagne capable of conquering all of Spain. The account is legend. Roland‚ a Frankish lord and Charlemagne’s own nephew. The "treachery" of the Christian Basques becomes transformed into the treachery of a single man‚ Ganelon‚ and the Basques themselves are replaced by Moslems‚ whom the poet calls Saracens or pagans

Diffusion and Osmosis Diffusion -the process by which molecules spread from areas of high concentratiion‚ to areas of low concentration. When the molecules are even throughout a space - it is called EQUILIBRIUM DIFFUSION Concentration gradient - a difference between concentrations in a space. Molecules will always move down the concentration gradient‚ toward areas of lesser concentration. Think of food coloring that spreads out in a glass of water‚ or air freshener sprayed in a room

Thomas Graham studied the behavior of the diffusion of gases of unequal densities when placed in contact with each other‚ using air as his control. He wanted to numerically prove how the diffusion of the gas volumes was inversely proportional to the value of the density of the gas‚ under constant temperature and pressure. The significance of this experiment was that in led to a reevaluation of the concept of the movement of matter‚ realizing that diffusion dealt with small immeasurable elements of

Were the Crusades Justified? In the case of the Crusades‚ the true jurisdictional limitation of the Church of Rome’s authoritative order was infinite beyond that of state or feudal control. It would seem that an “infinite jurisdiction” by any entity is unjust! The only possible rationale for having such unlimited authority would be an innate belief in “entitlement” or “unrestricted sovereignty.” The differences The Crusades were a succession of many wars‚ which “originally” started as a request

Who‚ or what‚ was responsible for the failure of the Third crusade? The third crusade was launched in 1189 due to the catastrophic defeat of Crusader forces at the Battle of the Hattin‚ in 1187‚ and the subsequent loss of Jerusalem. The news of this significant setback was‚ according to the chronicler Ernoul‚ so great that‚ Pope Urban died of grief when he heard the news. As a result‚ the newly elected Pope issued a Papal bull called the “Audita Tremendi” and in turn the three most powerful Christian
