is a crispy textured snack chip consisting of a special blend of whole wheat‚ corn‚ rice‚ and oat flours with a lightly salty multigrain taste and a slightly sweet aftertaste. The product contains less sodium than most snack chips and is made with canola or sunflower oil. The chip is approximately 50 percent lower in saturated fats than chips made with other cooking oils and is choles terol-free. According to a Frito-Lay executive‚it is "a thoughtful‚upscale classy chip." The product had been in test

Keegan Bauman Potato Lab Dr. Peano Block 1 Introduction: Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis‚ which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt‚ water and iodine solution. The dependent variable is the mass of the potato after being

| Stage 2 Biology | | Adelaide High School | [Osmosis Practical Report] Abstract: | The purpose of this investigation is to see if the concentration of Sodium chloride (NaCl) solution will affect the mass of the potato cylinder hence the rate of osmosis. This can be done by placing 5‚ identical in length (3cm) but different in weight‚ tubes of potato in 5 different beakers. Each containing an altered NaCl concentration. The concentrations used in this experiment were‚ 0%‚ 2%‚

Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration‚ in the direction that tends to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves‚ without input of energy‚ across a semipermeable membrane separating two solutions of different concentrations. Although osmosis does not require input of energy‚ it does use kinetic energy and

Basically‚ osmosis is the same action with diffusion but in water. To describe more precisely‚ osmosis is the net movement in water across partially permeable membrane‚ which mean the membrane allows the water to get through the

Potato Cell Cytoplasm Composition PURPOSE: To determine the concentration of salt in the cytoplasm of potato cells HYPOTHESIS: Increase in salt concentration results in a hypotonic solution where the mass of the potato increases due to the movement of water into the cell. On the other hand‚ decrease in salt concentration results in a hypertonic solution where the mass of the potato decreases due to the movement of water outside the cell. MATERIALS: Potato Forceps Stopwatch Scalpel Test

Osmosis Osmosis is a special example of diffusion. It is the diffusion of water through a partially permeable membrane from a more dilute solution to a more concentrated solution – down the water potential gradient) Note: diffusion and osmosis are both passive‚ i.e. energy from ATP is not used. A partially permeable membrane is a barrier that permits the passage of some substances but not others; it allows the passage of the solvent molecules but not some of the larger solute molecules.

Osmosis Abstract The basic principles of Osmosis and Diffusion were tested and examined in this lab. We examined the percent increase of mass and molarity of different concentrations of sucrose in the dialysis bag emerged in distilled water and the potato cores emerged in concentrations of sucrose. The data reinforces the principles of Osmosis and Diffusion‚ and in a biological context‚ we can simulate how water and particles move in and out of our own

supposed to hold up the structure of the cell keeping all organisms in alignment. Osmosis is the movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration‚ in order to equalize the solute concentrations on the two sides. We didn ’t know anything about osmosis except that it was a word in the dictionary that we never picked up. Osmosis and diffusion are similar because osmosis is the result of diffusion across a semi-permeable membrane. If two solutions

Aim To investigate the effects of increasing salinity on potato cell mass. Background Information This experiment is based upon osmosis. Osmosis can be defined as the net movement of water molecules from a region with high concentration to a region with low concentration. This movement must take place across a partially permeable membrane such as a cell wall‚ which lets smaller molecules such as water through but does not allow bigger molecules to pass through. This process will take place until
