needs Fabian Francis 081123090 Mr. A. Solomon Mico University College April 23, 2012 Introduction This anthology seeks to give readers an understanding of various disease and sickness students in a physical education class may suffer from. Time to time it has been a problem for students suffering from the disease, teachers and normal students in the class to react positively in a physical education class. As the motto of the Ministry of Education states that “Every child can learn, every

specific sequence of nucleotides that make up DNA. Most genes programme cells to synthesise proteins that produces an organisms inherited traits. Traits are organisms’ characteristics. The transmission of hereditary traits is based on the replication of DNA which produces copies of genes that can be passed on from parents to offspring. Humans have 46 chromosomes in almost all cells (apart from sex cells for example sperm and egg cells which are haploid or have half the number of chromosomes) Sexual

the topic of designer babies has raised some heads, as some are against it because they believe it’s playing God. Human Genetic engineering has been viewed as a way to cure hereditary diseases. There are over 3,000 diseases as a result of a genetic disorder. Conditions such as sickle-cell anemia, Tay-Sachs disease, Duchenne muscular dystrophy, Huntington's

* Describe the stress response in terms of hormones release and their effects over time? Stress is one of inevitable happening of our lives, it may be a physical, emotional stress, stress from our environment. Hans Selye says that our body is able to adopt this changes in 3 stages called the stress response or general adaptation syndrome: 1ST stage: fight or flight response- Rapid response and don’t last very long. Classic example is being chase by a bear. Heart rate and blood pressure goes

discoveries provided the foundation for the science of genetics. Mendel's findings continue to spur the work and hopes of scientists to uncover the mystery behind how our genes work and what they can reveal to us about the possibility of having certain diseases and conditions. The scientific field of genetics can help families affected by genetic disorders to have a better understanding about heredity, what causes various genetic disorders to occur, and what possible prevention strategies can be used to

Gene therapy is the transplantation of normal, healthy genes into cells in place of missing or defective ones in order to repair or replace the diseased causing cell, genes. How it works is correct the genetic disorders, like sickle cell, brain cancer and other cancerous cell and viral infections. Biotechnologist have found that there is still no quick rout to achieving this. Gene therapy is still at its experimental stages of treatment, but some of their findings have been promising.

acid in place of a glutamic acid changes the structure of haemoglobin which is less efficient at transporting oxygen. Normal haemoglobin exists as single units whether in relaxed or tensed form whereas sickle haemoglobin units bind together after dissociating with oxygen(harvard). This forms sickle haemoglobin polymers and prevents haemoglobin from undergoing ligand induced conformational changes and cooperativity regulation is no longer in

ESSAY ON ANAEMIA Anemia is a deficiency of red blood cells or hemoglobin in the blood. The word anemia comes from two Greek roots, together meaning “without blood.” At the beginning of the nineteenth century, “anemia” referred to the pallor of the skin and mucous membranes. After medical science advanced, blood cell counts could be done. Anemia became the disease we know today. Mild anemia may have no outer symptoms. Weakness, fatigue, and pallor are very common symptom. Symptoms of severe anemia

To live you need red blood cells, they carry oxygen around your body and keep you alive. In your bones, there is a red material called bone marrow, which, produces the red blood cells. When you have hemolytic anemia, your red blood cells die faster than the red blood cells made by the bone marrow. There are two types of hemolytic anemia, extrinsic or intrinsic. Extrinsic is often when the spleen takes healthy red blood cells and destroys them; other causes are, autoimmune disorders, infection, tumors
