    In this experiment‚ we had to demonstrate the process of osmosis using potatoes‚ and to determine the concentration of the cytoplasm of the potato. To demonstrate this‚ we had 6 test tubes and poured in different sucrose solutions of the following concentrations: 0.0M‚ 0.1M‚ 0.2M‚ 0.5M‚ and 1.0M. Once added in with all the sucrose solutions‚ we added in the 6 cylindrical potatoes of equal diameter and length. Before and after putting it in the potatoes‚ we had to weigh the initial and the final mass

    Effect of temperature and humidity on the transpiration rateof the whole mushrooms P.V. Mahajan * ‚ F.A.R. Oliveira‚ I. Macedo Department of Process and Chemical Engineering‚ University College Cork‚ Ireland Abstract Water loss or transpiration is an important physiological process that affects the main quality characteristics of fresh mushrooms‚such as saleable weight‚ appearance and texture. A loss in weight of only 5% may cause fresh produce to lose freshness and appear wiltedand it is an

    transport of materials in three semi-permeable membranes: dialysis tubing‚ eggs‚ and onion cells. Background Information 1. Diffusion is the movement of solutes from high to low concentration. Osmosis is the movement of water from low to high concentration. Both refer to movement in/out of a cell‚ but osmosis refers specifically to water. 2. Isotonic‚ hypertonic‚ and hypotonic all refer to the comparison of concentrations of solutes in verses out of the cell. Isotonic is when the concentration in

    NAME: Donna Ha TITLE: Measuring the Rate of Osmosis Using “De-shelled” Chicken Eggs INTRODUCTION: In order to fully understand the concept of this experiment‚ one must first be introduced to diffusion. Diffusion is a spontaneous process by which molecule particles move from one area that is highly concentrated to another area in which its concentration is lower. Cells contain fluids and are surrounded by fluids; in order for a cell to function it is required to be in a balanced state. The

    Osmosis Lab: Potatoes and Elodea Background Information: Cells have a need to regulate their internal environment. They need to be able to this because cells often find themselves in environments where the concentration of dissolved solids outside the cell is different from the number of dissolved solids inside the cell. Since the solids can not move across the membrane‚ the cell responds by moving water either into or out of the cell in an attempt to balance the number dissolved particles.

    calculate the fraction that will be used up after 6.0 minutes. 4. [15 points] The rate law for the decomposition of ozone to molecular oxygen 3 O3 (g) −→ 3 O2 (g) is rate = k [O3 ]2 . [O2 ] The mechanism for this process is k1 O3 O + O2 k−1 k 2 O + O3 −→ 2 O2 Derive a rate law from these elementary steps. Clearly state the assumptions you use in the derivation. Explain why the rate decreases with increasing O2 concentration. 5. [15 points] Consider the following

    EFFECT OF INTEREST RATE ON INVESTMENT DETERMINATION IN NIGERIA (1970-2008) ABSTRACT This study examines the effect of interest rate on investment determination in Nigeria. The study is necessitated by the fact that the behavior of interest rates to a large extent determines investment activities and economic growth of any country. Investment decision is seen as demand for credit in an economy and this study calculated the annual variance of interest rate and its effects on investment determination

    I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃‚ then
