Abstract This investigation was undertaken in order to observe the effects of changing the temperature of the solution that a potato cube is placed in. The temperatures that were tested in this investigation were 0°C‚ 20°C (room temperature)‚ and 70°C. This investigation tested the hypothesis: The rate of osmosis will increase as the temperature increases 2x2x2cm cubes of potato were weighed and then placed into 100mL of 10% NaCl solutions for 10 minutes. After 10 minutes the cubes were again

A summary of Diffusion of Innovations Les Robinson Fully revised and rewritten Jan 2009 Diffusion of Innovations seeks to explain how innovations are taken up in a population. An innovation is an idea‚ behaviour‚ or object that is perceived as new by its audience. Diffusion of Innovations offers three valuable insights into the process of social change: - What qualities make an innovation spread successfully. - The importance of peer-peer conversations and peer networks.

Scientific Paper on Diffusion 2 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using two tests: the glass tube test and the agar-water gel test. In the glass tube set-up‚ two cotton plugs soaked in two different substances (HCl and NH4OH) were inserted into the two ends of the glass tube. The substance with the lighter molecular weight value (NH4OH‚ M = 35.0459 g/mole) diffused at a faster rate (dAve = 25.8cm)‚ resulting in the formation of a white ring around the

Potatoes are an excellent metaphor for Angus Buchan’s book‚ Faith Like Potatoes. A good-looking stalk may hide a rotten crop under ground. As is taught by Christianity‚ you may be successful in this world without God‚ but there will always be that Christ shaped empty space in your heart that only God himself may fill for any one person to be happy. Angus Buchan was born into Southern Rhodesia‚ which is now modern day Zimbabwe. He grows up as a Christian and is slowly drawn away from Christ as

pore protein 3. carrier protein SIMPLE DIFFUSION What is diffusion? Diffusion is the movement of particles from a high density region to a low density region. No energy is needed and no membrane involves in diffusion. The Dynamic Equilibrium Diffusion will continue until the concentration in all region is the same. When this happen‚ we say it has reached the dynamic equilibrium. Factors Affecting the Rate of Diffusion (How fast diffusion happens) Particles that Move Through

1. Living organisms play an important role in the recycling of many elements within an ecosystem. One such way this idea can be proven is through the study of carbon in an ecosystem. Plants‚ for starters‚ are a major part of this carbon cycle. During photosynthesis‚ plants remove carbon dioxide from the atmosphere and release oxygen as a waste product. Another major contributor to this vital cycle is the human being. The average human being goes through respiration each day to help maintain

Labs 4 & 5 Lab Four: Experiment 1 1. At what magnification do you first notice the ragweed pollen? I first noticed it when the magnification is at about 30 2. Which is bigger‚ rhinovirus or E. Coli? E. Coli is bigger 3. Based on the magnification‚ how many of the E. Coli can fit into the same space as the head of a pin? 10‚000 E. Coli 4. About how many red blood cells could fit across the diameter of a human hair. (Again‚ look at the magnification scale)? About 100 blood cells

Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport without requiring bulk motion. Thus‚ diffusion should not be confused with convection or advection‚ which are other transport mechanisms that use bulk motion to move particles from one place to another. In Latin‚ "diffundere" means "to spread out". There are two ways to introduce the notion of diffusion: either a phenomenological approach starting
