  • What Are Stem Cell?

    What Are Stem Cell?

    STEM CELL WHAT ARE STEM CELL? All of us start from a single cell formed at conception, when a sperm cell joins with an egg. This cell then starts dividing and forms a ball of cells. About four days after conception, this ball of cells is smaller than a pinpoint. This process, called differentiation, allows some cells to become liver cells and other cells to become nerve cells or skin cells and so on. This

    Car Engine, Brief Fuel System Explanation

    THE FUEL SYSTEM The fuel system pumps fuel from the tank and mixes it with air so that the proper air/fuel mixture can flow into the cylinders (because to make the little explosion to work it needs oxygen) then it give out a little spark. Fuel is delivered in three common ways: carburetion, port fuel injection and direct fuel injection. • In carburetion, a mechanism called a carburetor mixes fuel into air as the air

  • Sickle Cell Disease

    Sickle Cell Disease

    Sickle Cell Disease is a hereditary blood disorder that affects the oxygen-carrying part of blood, the red blood cell. In other words, it is visible by diseased red blood cells that have a sickle shape. Red blood cells have proteins called hemoglobin. Hemoglobin transports oxygen from your lungs to every part of your body. When a normal red blood cell (with normal hemoglobin) releases its oxygen, it maintains its disc shape. However, when a diseased

  • Sickle Cell Anemia

    Sickle Cell Anemia

    Sickle Cell anemia is a blood disease that is inherited by the parents and lasts forever. The ones that have this disease inherit two genes from each parent that are abnormal which are the sickle cell genes. These genes inform the body to make abnormal hemoglobin which causes the red blood cells to be deformed. A single change in the amino acid building blocks of hemoglobin causes the sickle cell mutation. The changes in

    Stem Cell Stem cell research has been a major controversy for the last few years. But what exactly is a stem cell? Stem cells have the remarkable potential to develop into many different cell types in the body. Serving as a sort of repair system for the body, they can “theoretically” divide without limit to replenish other cells as long as the person is alive. When a stem cell divides, each new cell has the

    Developing Female and Male Germ Cells in Fetilisation

    The female and male germ cells are reproductive cells that fuse with one another during fertilization (Burfoot, 1999). Each possesses unique characteristics and molecular structure during the pre-fertilization phase of development and post-fertilization. These characteristics are influenced by the production of various hormones in the male and female body. Fertilization occurs when the materials from two gametes come together to form an embryo. The female gamete is often referred to as the egg or female

    Stem Cells and Therapeutic Cloning

    Stem Cells and Therapeutic Cloning Embryonic stem cells were grown in a laboratory successfully in 1998. At that time researchers were able to have the stem cells begin copying themselves without becoming anything further (Easterbrook, 2000). This was an exciting time for researchers to begin discovering this new technology. The therapeutic cloning process begins when the nucleus is removed from a human egg and replaced with the nucleus of a body cell from the person
