significant differences in the growth patterns of Vigna radiata when grown under varying light intensities. Plants were grown in two different light intensities‚ normal light and no light‚ for a period of 10 days to determine two different phototrophic effects. The results demonstrated that there was a significant difference between the internode lengths of V. radiata grown under the different light intensities‚ with the plants grown in normal light having shorter internode lengths than the plants grown

Experiment 20: pH Titration: Phosphoric Acid in Cola Drinks Post-lab Assignment or Report The post-lab report for this experiment is due at the beginning of the following lab period. Student notes for the lab will be available on the lab T-Square site. Learning Objectives Students will be able to... • Use a known mass of solid acid to determine an unknown concentration of a basic solution (this process is called “standardization”). • Execute a titration using good‚ reliable technique.

Question 1 Critique Dr. Honeydew’s report. Specifically‚ discuss what is missing and how the missing information should have been presented. First the PH measurements‚ Dr. honey dew does not explain how the PH device was calibrated or if the blood sample was added or mixed with anything prior to the measuring of the pH (like water‚ etc.). In regards to the absorption spectroscopy‚ the method by which the concentration was obtained is questionable. Was the concentration known before the experiment

Notes about bean germination: * The time to germination will decrease if you soak the beans overnight * It may take 7-10 days for the beans to ‘sprout’ * Make sure the paper towels remain moist for the duration of your experiment | | | | | | | | | | Procedure 1. Think of 10-20 variables that may affect seed germination‚ recording them in Table 3. 2. From your list of variables in Table 3‚ select three to test. Form a hypothesis for why each affects seed germination

The Effect of Microwave Radiation on the Respiration Rate of Phaseolus vulgaris Aerobic Celluar Respiration is a process that is carried out by most living organisms. The process is a series of chemical reactions that occur within the mitochondrial matrix and cristae of eukaryotic cells. Following the anaerobic process of glycolysis‚ partially broken down sugar molecules enter the matrix of the mitochondria where they are further reduced by oxygen. In the process‚ a small amount of ATP is created

Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise

Re: L.L. Bean‚ Inc. Overview When working in the catalog industry and a customer calls in and wants to order a red sweater and you are out of red sweaters‚ the company might have just lost the sale if the customer does not want a substitute colored sweater. This is the part of the continuous problem that L.L. Bean‚ Inc. has with item forecasting and inventory management. Working in a catalog business really helps companies to capture demand‚ but the problem most companies have is matching demand

3. LL Bean utilizes a probability distribution methodology to help predict the optimal order size of a specific item. The probability distribution is driven by a series of calculations that will predict forecast errors. One of the major concerns is that LL Bean tends to order more inventory than what was predicted in the frozen forecast. Their logic for doing this is that the cost of understocking exceeds the cost of overstocking. According to Marck Fasold (CFO)‚ this methodology leads to major discrepancies
