When the Irish Potato Famine Struck Ireland On a sunny morning in 1845‚ Irish farmers were going to check their crops. A farmer named Abraham Fitz found black potatoes in his fields. He thought it may be only the one‚ so he moved over 4 rows and dug another potato out of the ground. This one was black and rotten. This causes Abraham to travel to his neighbors house and ask about their potatoes. His neighbor’s potatoes were black‚ rotten‚ and giving off a foul stench. This would later be discovered

Potato Chip Monopoly ECO204: Principles of Microeconomics Instructor: A monopoly is an industry composed of only one firm that produces a product for which there are no close substitutions and in which significant barriers exist to prevent new firms from entering into the industry (Case‚ 2009). In a different definition‚ it can be distinguished by a lack of financially viable competition to produce the goods or services as well as to substitute goods. Monopolies often refer to a procedure

Osmosis Osmosis is just a special case of diffusion - where water diffuses through a membrane which has different concentrations on either side. Permeable means "allows anything to pass through". Membranes in cells allow small molecules (water) to pass through‚ but prevent bigger ones from passing. This is called "selectively permeable". Take a look at the following animation; If a selectively permeable membrane separates the two solutions‚ water moves through it in both directions at

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

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
Premium Concentration
The Process of Osmosis and its Importance to Living Organisms. Osmosis is the diffusion of water through a semipermeable membrane that does not allow dissolved solids (solutes) to pass. Osmosis refers only to diffusion of water and the direction of movement is from the area of higher concentration to the area of lower concentration. This migration of water from a region of higher concentration to a region of lower concentration is spontaneous and although water molecules move in both directions

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

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
