    Lab: investigating hooked law with springs
 
Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle 
Pre lab predictions:

We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like

Data: Spring #1: y = 8.2941x + 0.0685

    of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

    Toxicology Lab      1. In  this investigation‚ a wide range of concentrations of  Sodium Chloride (NaCl) solution  were   created   and  the  effects  that  they  had  on  radish   seeds  were  tested.  This  ultimately  created  a  dose­response  experiment  in  which  it  was  detectable whether  or  not  radish  seeds  were  a  reliable  bioassay  for  the   toxicity  of  NaCl.  The  goal  of  this  experiment  was  to  determine  a  correlation  between  toxicity  and  seed  germination/radicle

    functioning of the cell or the organelle of which it is a part. A membrane’s permeability is related to its phospholipids and transport proteins. (Danyk‚ 2013/14) This study involves observing the effects of temperature and detergent concentration (%SDS) on beet cell membrane integrity and how the loss of membrane integrity leads to loss of membrane function. (Danyk‚ 2013/14) SDS increases the staining intensity(Brown‚ Lydon et al. 1996) since it removes the proteins embedded in the cell membrane(Freeman‚

    Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

    Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

    Damage of Beet Cell Membranes Caused by Different Temperatures Resulting in Betacyanin Leakage By: Trevor Sandum‚ Lab 2‚ March 9‚ 2013 Introduction: A red pigment called Betacyanin located in the vacuole of the beet cells is released when the membrane is damaged (Danyk‚ 2013). The membrane is necessary for sustainability of the cell’s life‚ it separates the cell from the outside environment‚ and is responsible for diffusion‚ exocytosis and endocytosis‚ and transport. It

    The Effect of Solvent Exposure and Temperature on Beet Cell Membrane Integrity Introduction: • Cell membranes are vital to proper cellular function • Cell membranes consist of a lipid bilayer made up of phospholipids • Phospholipids are amphipathic molecules meaning they have a dual nature in that they show both hydrophilic (water-loving) and hydrophobic (water-fearing) properties • The amphipathic nature of phospholipids causes them to spontaneously form bilayers in water
