Joshua Annan Biology Section-04 Diffusion and Osmosis December 14‚2012 Alexis‚ Adiba‚ Elliot and Joey Purpose: The purpose of this lab is to get a better understanding of osmosis and diffusion in molecules. We will do this by studying different solutions and how they move through the permeable membrane. Hypothesis: The three different possible predictions were the lab were that the mass would stay the same‚ the mass will increase‚ or the mass will decrease

The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between

AP Biology Osmosis and Diffusion Lab I. Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion. Diffusion is a movement from a higher

Mr. Reeves Page 1 Cultural Diffusion in the Ancient World Throughout history‚ cultures have mixed all over the world‚ changing beliefs‚ creating new ones‚ and changing the way people look at the world along with their existence. This can be proven from anything from music to food‚ but is especially prevalent in world religion and the way that every culture sees their god‚ or gods‚ and how they think‚ worship‚ and even obey‚ in similar manners.
