globalization of markets and the importance of innovation are independent of one another. 2. Flexible manufacturing technologies have increased the importance of production economies of scale. 3. Innovation and new technology have led to longer product life cycles as better quality products are being produced. 4. The increased pace of innovation has only had a negligible effect on market segmentation and product obsolescence. 5. Slow innovation results in diminishing margins and product

Part A: Diffusion on a liquid in a liquid. I did an experiment with three different glasses of tap water from the faucet. All three cups measured the same which happened to be 13 cm from the top of the cup to the bottom of the cup. I let the water settle‚ and sit for about an hour so the temperature was the same for all three cups. I then placed one drop of food coloring into the first glass and waited for the coloring to reach the bottom. I calculated 93 seconds. I then went to the second glass

THE EFFECT OF THE WATER CONCENTRATION GRADIENT ON THE RATE OF OSMOSIS Investigation Folio: Summative Stage 1 Biology: SEMESTER 1 2014 MARCIA SHAW - 151003X INTRODUCTION Diffusion: is when something spreads more widely from a higher concentration gradient to a lower concentration gradient. Diffusion is the process from which molecules‚ atoms or ions mingle together and move from an area of high concentration to an area of low concentration as a result to their kinetic energy. for example

Cell Size: Is Bigger Better? Problem: Why are cells small? Objective: To see the relationship between cell size and diffusion of materials. Hypothesis: If we cut three different sizes of cells‚ then the smallest one will survive the longest due to its sufficient permeable membrane.

Lab Report Diffusion is - One of two kinds of passive transport‚ - Diffusion can transport ions from higher concentration to lower concentration region without any other forces. - A net movement of molecules in and out of cell membrane - Diffusion can be affected by the steepness of the concentration gradient. Lab question: Is the rate of diffusion influenced by the presence of second molecule? Prediction: the rate of diffusion is influenced by the presence of second molecule
