    this Lab the students dealt with Osmosis‚ movement of water molecule or solvent from a high concentration to a low concentration‚ through selective permeability‚ a protective barrier that provide some particle the ’direct ’ passage in and out of the plasma membrane ( Lacerda L.2011) Allowing some molecules enter and exit the cell membrane‚ to create a balance in concentration inside and outside of the cell‚ by doing so the cell often become hypotonic‚ where the concentration outside the cell is higher

    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

    Pluripotent Stem Cells and Embryonic Stem Cells Induced pluripotent stem (iPS) cells made from human somatic cells are a very recent technology of our world. They were first created using mice in 2006‚ and were created from human cells in 2007 by Japanese and US scientists. For many people‚ they represent a beautiful work of science that will help to save many lives. Induced pluripotent stem cells are human skin cells that have been reprogrammed to have the stem cells ability to differentiate

    this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis.   Purpose The objectives of the lab were to help give us a better understanding of cell cycles

    microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny‚ three dimensional sac which is in fact made up of many components‚ each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own‚ individual function which helps a cell to function and maintains the cell membrane. The components that I will
