    Discussion: Spinacia oleracea like many other plants contains leaves which play a crucial role in the process of photosynthesis. The energy used to drive the chemical reactions within photosynthesis comes from the sunlight absorbed by the chlorophyll molecules (Merzlyak, Chivkunova, Zhigalova, & Naqvi 2009). These chlorophyll molecules then transfer the light energy to chloroplasts and that light energy is converted into chemical energy (Merzlyak, Chivkunova, Zhigalova, & Naqvi 2009).…

    Title: Alexandra Whitaker, Ms.Dayton, 12/23/16, 2.03 lab permeability Objective(s): The main purpose is to find out if plastic bags are permeable to starch and, or, iodine. Also, to find out wither potatoes are hypotonic, hypertonic, or isotonic by testing the different amounts of sucrose solutions Introduction: The necessary background information needed for this lab is the definition of osmosis, diffusion, active transports, passive transports, permeability, concentration, tonicity, and to now the scientific concepts of hypotonic, isotonic, and hypertonic. Hypothesis: For part 1 my hypothesis is: That the starch will diffuse across the plastic bag and react with the iodine and will have a color change to the water to imply the reaction…

    The purpose of this lab is to determine the Ka of an indicator within an unknown solution. This can be determined because acid-base indicators are weak bases or acids, and when neutralized they change colors. The color change is measured by the light absorption spectra in the compound which can be used to calculate the concentration. This experiment measures the concentrations by the different pH values which allows the pKa and Ka to be determined. Through the experiment, and the recorded color change with the use of the Spec 20 the unknown Ka of the solution was found.…

    A small burette funnel was filled with column packing solvent at mobile phase, high boiling petroleum, in this case hexane (and then 10%acetone hexane mixture), and Alumina as stationary phase. When adding the sand and the alumina they have to be first mixed with the hexanes in order not to disturb the column. The Lycopene is Red- Orange and more attracted to alumina due to its high degree of Unsaturation, which can be expected to be eluted after Yellow-Orange Carotene pigments. And the other pigments such as Xanthophylls, which are more polar due to their hydroxyl group, are strongly attracted to Alumina, which would be eluted after Lycopene band. The column should be covered by aluminum foil to prevent Isomerisation of Lycopene by light.…

    I was fascinated to learn about the elements in Art. I had always thought that art had no organization, guidance or system. I thought that people just painted or drew pretty much whatever they wanted with no apparent rules. The Visual Elements that Getlein mentions on chapter 4 consist of the following; line shape and mass, light, color, texture and pattern and last but not least; time and motion (Getlein, 2012). These elements are intrinsically woven in art!…
