Biology diffusion Science ISA To find out if concentration affects the rate of diffusion. I predict that the higher the concentration of acid the faster the reaction will be. Dependent variable: We are measuring the time taken for the pink indicator to turn clear when hydrochloric acid is added to it. Independent variable: We are changing the molar of hydrochloric acid we are adding to the gelatine cubes. Apparatus: * 1 measuring cylinder * 1 test tube * 1 stop clock * A large gelatine

The Bystander Effect I. Introduction: A. Attention Getter: After the Giants won the Super Bowl in 2012‚ they did what most football teams do to celebrate. After going to Disneyworld‚ they held a parade through the streets of New York. During the parade‚ a fight broke out between a Giants fan and‚ of course‚ a Jets fan‚ the cause of which might seem obvious. Immediately‚ spectators did what anyone might do when they see a fight break out. They…..pulled out their phones and videotaped it. And from

CASE Investors (venture capitalists) knew the potential was good for Techtron Computers to challenge the dominant players in the high-speed computing market. They also knew the types of computers Techtron hoped to bring to market were a long shot for success even with their significant financial investment. The four founders of Techtron all had come from large international corporations known for their high-speed

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 bystander effect could happen for three main reasons which are the pluralistic ignorance‚ the social inhibition‚ and the diffusion of responsibility. The bystander effect also got the name

allowed Subway to be a very good example of diffusion of innovation with the company being placed in the model rather than the consumers. Each subway franchise acts as its own business or is part of a mini chain of franchises; nonetheless this allows a large degree of innovation to occur since individual stores will become increasingly creative to meet the needs of their individual markets. This then allows the company as a whole to fit in to the diffusion of innovation model as innovators‚ early adopters

cells does not change‚ means there is no net loss or gain of water. Introduction This study shares the results of an effort to understand diffusion and osmosis in general. It focused more into osmosis in plants cell‚ and how to indirectly measure osmolarity in potato tuber tissue. Osmosis is the diffusion specifically of water across a membrane. Diffusion occurs when certain substance‚ such as an ion‚ is more concentrated on one side of membrane. If the membrane allows this ion through‚ the ions

The purpose of this lab was to observe the rate of osmosis and diffusion‚ as well as the effect of molecular size of the particles on this rate. Part I of the lab was a demonstration of osmosis and diffusion‚ that dealt with raisins in different liquid environments‚ each with a different concentration of sugar. Part IV of the lab was using the same idea as the demonstration‚ by putting objects in different concentrations of a substance; in this case elodea leaves in salt water. In both cases‚ the
