An Action Potential in a Neuron Essay Preview: An Action Potential in a Neuron Report this essay This essay will describe the electrochemical processes that allow an Action potential to occur in a neuron. This will be achieved by firstly, defining the purpose of neurons in the body along with a description of the components.
Osmosis Case Essay Preview: Osmosis Case Report this essay Osmosis is the movement of water from a high water concentrate to a low water concentrate. It takes place across as a barricade such as a cell membrane which is selectively permeable. This means that it only lets through tiny molecules like water and does not.
Biology Coursework Condensation reaction – two molecules combine and produce a water moleculeHydrolysis reaction – this is when water is added to a bond which causes it to break.Monosaccharide is a basic monomer and can combine to form a disaccharide or a polysaccharide Glucose joined to glucose forms maltoseGlucose joined to fructose forms sucroseGlucose joined.
Happy The amoeba is a protozoan that belongs to the Kingdom Protista. The name amoeba comes from the Greek word amoibe, which means change. Protists are microscopic unicellular organisms that dont fit into the other kingdoms. Some protists are considered plant-like while others are considered animal-like. The amoeba is considered an animal-like protist (protozoan) because.

Science Questions Essay title: Science Questions Active transport- The movement of a chemical substance through a gradient of concentration or electrical potential in the direction opposite to normal diffusion, requiring the expenditure of energy: active transport across a cell membrane. Cell- The smallest structural unit of an organism that is capable of independent functioning, consisting.
Diffusion with Surface Area to Volume Ratio Join now to read essay Diffusion with Surface Area to Volume Ratio Introduction Cells have to interact with their environment, chemicals and water and in order to do so they must be able to move across the cell membrane and the cell. The movements within a cell are.
Cells and Their Parts Essay Preview: Cells and Their Parts Report this essay Cells are some of the smallest organisms around. All living things consist of cells, and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which.
The Cell Membrane in CellsEssay title: The Cell Membrane in CellsThis can be seen in living cells. The cell membrane in cells is semi-permeable and the vacuole contains a sugar/salt solution. So when a cell is placed in distilled water (high water concentration) water will move across the semi-permeable membrane into the cell (lower water.
