Process of Diffusion and its importance in living organisms Diffusion is the movement of molecules or ions down a concentration gradient i.e. from an area of high concentration to an area of low concentration. For a diffusion system to be efficient‚ it should have a large surface area so that high amount of substances can be exchanged at a time. It should also have a thin membrane and a continuous supply of substances‚ as a thin membrane means that the diffusion pathway would be short‚ and the continuous

increasingly important. That question is: do animals have rights? Here we examine what gives humans their rights and see why animals are entitled to the same rights based on the same claims for human rights. There is no evidence that supports human’s rights and also clearly excluded animals. In order to answer this question which comes up so frequently‚ the question its self must be clarified. What do we mean by animals? And what to mean by rights? Humans have been given a set of rights at birth‚ so we are

Diffusion and Osmosis lab Results: Figure 1a-rate of weight change in 15 min intervals of each concentration. The first tube showed very little weight change. However all other tubes show a greater change the concentration could be the factor that determines the permeability of the sucrose. The sucrose molecules are too large to pass through. Figure 1b- sucrose concentration determines the weight change. In this case based on our results as concentration increases the percent weight change

As trade along the Silk Road grew‚ Chinese weavers wanted to design silks that would appeal to other cultures. (Cultural Diffusion & the Silk Route of Ancient China) Some examples of this are the silk rugs called “ The Tree of Life‚” that reflected upon the Persian culture. This rug contained the roundel animal symbol and scenes of saddled horsemen. They used thread wrapped

The Rate of Diffusion in Different Temperatures Purpose: To see if the temperature of a solution will change the rate blue diffuses in it. This will be tested by timing how long it takes dye to diffuse in warm water‚ cold water‚ and room temperature water. Hypothesis: I think that the dye will diffuse at a faster rate in the warm water than in the cold water. I believe that the room temperature water will have the dye diffuse faster than the cold water but slower than the warm water. Variable:

Y Tu Mama Tambien is rather a unique movie‚ in which the director and writers did a good job in producing it to be a symbolic film. What I find to have been the most interesting part of the movie was the role of the narrator. Throughout the course of the movie‚ the narrator would enter into a scene with a rather detached tone and omniscience role‚ by revealing truths about each character which they refuse to acknowledge or even cannot know. This coincides with the fact that everyone does have their

Biology Lab #1: Chemical Diffusion Purpose To discover how the size of a cell affects the diffusion of chemicals throughout the cell. Hypothesis I predict that as the cell size increases the diffusion depth and the diffusion rate will decrease.
