Martina Oganesyan Title of investigation: The effect of solute concentration on osmosis in potatoes. Research question: What is the solute concentration of a potato? Hypothesis: Osmosis is the movement of water across the membrane from an area of high concentration to an area of low concentration. The osmosis continues until the solute concentrations are equal in both areas. In this experiment‚ we put pieces of potatoes into test tubes with sugar solutions of different concentrations and leave

Monopoly for the Potato Chip Industry A monopoly is a company that provides a product or service for which there are no close replacements and in which significant barriers of entry can either prevent or hinder a new company from providing competition (Case‚ et al.‚ 2009). Take into consideration the potato chip industry in the Northwest are not only competitively structured but are in long-run equilibriums. The firms were earning a normal rate of returns and were competing in a monopolistically

Potato Chips Jacquelyn opens the yellow bag‚ feeling the smell of the chips engulf her. Then the memories come‚ forcing themselves to the front of her mind. Jackie returns from the kitchen with a bright yellow bag‚ brighter than the morning sun. She grabs the top between her fingers‚ the crackle of the bag alerts Jimmy of what she has. Jackie pulls apart the bag‚ feeling the rush of air towards her face. The smell of cholesterol engulfs her. She reaches in and pulls out one of the golden crisps

The Effect of pH on Enzyme Activity A piece of Solanum tuberosum (potato) was removed and mixed with distilled water in a blender. The resulting solution was filtered through multiple layers of cheese cloth to filter out the liquid by eliminating any large pieces in the solution. The solution created was catechol. Five different solutions were prepared as blanks with each test tube containing 6.0mL of a different pH (pH 4‚ pH6‚ pH7‚ pH8‚ pH10) of phosphate buffer‚ 1.0mL of the enzyme and 1.0mL of

Diffusion and Osmosis of Solutes and Water Across a Membrane Brittany Bacallao Nova Southeastern University Abstract: This experiment gave a visual understanding of osmosis and diffusion. The first experiment proved that solutes would move down a concentration gradient if permeable to the selective membrane. The second experiment proved different solute concentrations affect the movement of water‚ depending on the solute concentration inside the cell. The purpose of this lab was to look for

which came from the potato juice. The function of an enzyme is to catalyze reactions in cells. The specific function of the enzyme in this experiment was to see if it affected the activity if it was exposed to different temperatures. A substrate is a material or substance which the enzyme acts. The substrate in our lab was hydrogen peroxide. Procedure For our experiment we used‚ three test tubes‚ nine milliliters of potato

Introduction In Diffusion‚ Dialysis & Osmosis lab‚ we discovered that we were going to observe and understand the conditions under which diffusion‚ dialysis‚ and osmosis occur. Then we constructed models of diffusion‚ dialysis‚ and osmosis. We predicted that the direction of change would be from the membrane to the beaker. We understood how these processes affected the selectivity of the cell membrane. The second part of the lab was dealing with dialysis. In this part we studied starch and sodium

Reverse Osmosis Application Assignment Osmosis is the dissemination of water atoms through a semi-permeable layer from areas of high to low concentration in the direction that tends to equalize the solute concentration on both sides. In real life osmosis is found in roots of plants retain water from the dirt‚ and kidneys taking water from blood [5]. Reverse osmosis is the removal of solute from water by applying pressure to the water and moving the solution through a semi-permeable membrane. It is

General Anatomy and Physiology Case Studies - Osmosis These two Case Studies come from a National Center on Case Studies. I think that a case study approach is very useful in applying knowledge and this is what makes you learn it better. They may be a little daunting when you read them but I will help you go through them. Please ask for help so this topic becomes more enjoyable for you.

Brownian motion This is‚ presumably the random drifting of particles suspended in a fluid (a liquid or a gas) .This movement was discovered and later named after botanist Robert Brown (1773-1858). He was a Scottish botanist and palaeobotanist who made important contributions (including Brownian motion) to botany largely through his pioneering use of the microscope. The scientist who made Brownian motion famous is Albert Einstein‚ who brought the phenomenon to the attention of the larger physics community
