There are many ways in which substances can move across the cell membrane and in which then helps in the function of the body (cells‚ tissues and organs) overall. There are 3 processes that a substance can move across the membrane‚ theses are diffusion (simple and facilitated)‚ osmosis and active transport. Both diffusion and osmosis are passive processes‚ which mean they do not need energy to occur‚ whereas active transport does require energy. All three processes are involved in many functions

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

Thermal Conductivity of Metals and Non-metals 1. Introduction Thermal conductivity is a physical property of materials of great importance. Unlike some physical properties‚ however‚ thermal conductivity cannot be directly measured. In order to determine a material’s thermal conductivity‚ intermediate quantities must be determined from which the conductivity may be ultimately calculated. The objective of this lab was to determine the thermal conductivity of metals. To do so‚ it was necessary to study

can have it more than once. The differences between a virus and a bacterium are thus: * Bacteria are unicellular‚ Viruses have no cells. * Bacteria have DNA and RNA floating in cytoplasm‚ and a cell wall and membrane. Viruses have DNA or RNA enclosed in a protein coat. * Bacteria have Ribosomes‚ whereas viruses do not. * Bacterial infections are localised‚ yet viruses are systemic. As you can see‚ there are a load of differences between viruses and bacteria‚ however there

Lab Report Electrical Conductivity Introduction There are some substances that are capable of conducting electricity‚ and the reason they conduct electricity is because of the type of compound the substance is. Electrolytes or any ionic compound conduct electricity and nonelectrolytes do not conduct electricity. An Ionic compound is formed from the electrical attraction between anions and cations‚ typically a metal with a non-metal‚ except hydrogen. When an ionic compound forms‚ the anion
