To do this successfully I will need to alter the surface area of the beetroot cells accurately and then measure if any and how much dye is let out. I can hopefully then look at my results and then find a relationship between the two factors and be able to explain exactly why any changes took place. PREDICTION For this experiment I would expect the leakage of dye to increase as the surface area increases and this is based on the knowledge of the formation of membranes. Membranes are made of two

the complete DNA sequences of many animal‚ plant‚ and microbial genomes. The first DNA sequences were obtained in the early 1970s by academic researchers using laborious methods based on two-dimensional chromatography. Following the development of dye-based sequencing methods with automated analysis‚[1]DNA sequencing has become easier and orders of magnitude[clarification needed] faster.

Introduction Photosynthesis is a redox reaction which requires carbon dioxide‚ water and light to produce water and a 6-carbon sugar. The process of photosynthesis consists of two parts‚ a light reaction and a light-independent reaction. The method of changing light energy into chemical energy for the formation of NADPH and ATP is done through the light reactions. Light independent reactions use carbon dioxide and the products of light reactions (ATP and NADPH) to form compounds such as glucose

upon viewing under the microscope. Iodine-Potassium-Iodide (IKI) and Sudan IV were the dyes used to stain specific parts of the plant tissue. IKI is used to stain structures containing starch which is indicated by the color change from brown to reddish-brown or blue-black. The stem‚ leaf‚ and root cross sections all contain starch. The roots stained the darkest meaning starch is stored more in them. Sudan IV dye stains lipids into pink to red color. All cells in a plant tissue contain lipids so the

Chromatography: How can we separate a mixture? Purpose The chromatography lab is to understand how molecules with similar molecular properties can be separated with paper chromatography. These differences will be interpreted to see the distinction of separate chemical substances. Pre Lab Questions 1. Explain capillary action as it pertains to water and paper. Capillary action makes water draw up the paper. As paper absorbs water mixes with the solutions in the paper. 2. What is the

The absorbance of Disulfonic Acid in the experimental trial was 608nm with an absorbance of 1.037 with Beer’s law the epsilon value was determined to be 22416.67m-1c-1. The percent yield of the second indigo Carmine experiment was determined to be 7.55%‚ 8.06%‚ 6.91%‚ 5.10% and 4.72%. Introduction: This is a two week experiment involving transformation of matter where we will investigate the synthesis of the dye indigo‚ which will be made‚ isolated

and the characteristic of the flow. Other than that‚ the range for laminar and turbulent flow can be calculated and the theory that Reynolds number is dimensionless can be proven. The pump is opened to let the water flow. The dye injector valve is opened to let the dye flow into the glass tube which act as an indicator to the fluid behavior either it is laminar‚ transition or turbulent. The volume of water from outlet valve need to be collected for 10 second after the fluid motion is stabilized
