Being a couch potato is what many of us tend to be when we are on a break or on a holiday but why not try to do something different and useful that could bring benefits to one’s self? Earning additional cash over the internet could be let us just say one of the most beneficial way to kill time. Making extra cash is not easy but it is definitely worth the effort because the extra cash could come in handy during the rainy days. Besides‚ it’s easier earning some side income through the internet than

Discussion: Osmosis is a passive process by which water molecules move through a partially permeable membrane from a region of high concentration to a region of low concentration‚ creating an equal amount of molecules from both regions on each side of the membrane. This process is the result of a downhill energy system known as water potential. Water potential is the potential energy of water (per unit volume) that allows it to move from one area to another by osmosis. This system causes the water

The Effect of pH on the Rate of Osmosis Using a Glucose Solution Melissa Werderitch Biology 157 11/6/06 Introduction In a journal article written by Florian Lang‚ osmosis is essentially explained as the flow of water from one area to another that are separated by a selectively permeable membrane to equalize concentrations of particles in the two locations (Lang‚ 1997). Osmosis is able to maintain osmotic pressure and regulate a cell’s volume. In a hypotonic () or hypertonic () environment

Potato Battery Chapter I: Introduction I. Background of the Study Do you have like 500 unused sacks of potatoes and don’t know what to do with it? Does your low class battery always die out on you at the exact moment you look at the last digit of you clock? If you answered yes‚ then here is the solution to your problem! Potato batteries are designed for you! So why do you spend so much money in buying new batteries for your digital clock if you can use the alternative resource. II. Statement

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

BIOLOGY OSMOSIS LAB REPORT 1. Research Question/ Aim How do the different sodium chloride concentrations of solutions affect the length (measured in mm) and mass (measured in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases‚ the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores‚ there will be

The Effects of Osmosis and Diffusion The experimentation of last week’s lab was in order to test the many effects of diffusion and osmosis amongst four experiments. One such experiment was testing the effects of molecular weight on diffusion in relation to the use of Agar. The methods performed included the use of two acids‚ HCl and acetic acid. Both acids were placed into an Agar-filled dish and‚ over increments of 15 minutes‚ data collection was taken based off the diffusion rate and the
