multicellular organisms‚ the cells that make up their respective organisms have different structures depending on their function. The process in which cells get specialized is known as differentiation. Unspecialized cells‚ known as stem cells‚ can be called upon to replace damaged or aging tissues‚ or create new tissue for growth. An example of specialization can be found with blood cells. Every blood cell originates from the bone marrow‚ starting as a unspecialized stem cell known as a multipotential

Stem cells are pluripotent cells present in all living organisms. These cells can differentiate into any type of cell‚ including nerves and cardiac muscle. The scientific community is very excited about the possibility of these undifferentiated cells being used to treat conditions such as spinal cord injuries‚ diabetes‚ and cancer. Despite the enormous potential for medical advancements‚ controversy surrounds the sources and methods of acquiring stem cells and the possible improper uses of the knowledge

The sickle cell disease is an inherited blood disorder that affects red blood cells. People with sickle cell have red blood cells that have mostly hemoglobin’s‚ Sometimes these red blood cells become sickle-shaped or crescent shaped and have trouble going through small blood vessels. When sickle-shaped cells block small blood vessels‚ less blood can get to that part of the body. Tissue that does not get a normal blood flow eventually becomes damaged.This is what causes the problems of sickle

discovered the endless possibilities of the so called embryonic stem cells. It has been said that these cells have the ability to repair an entire tissue or even create a copy of it. It is also said to be a potential cure for innumerable serious diseases such as the Alzheimer and the Parkinson’s disease. This is why stem cell research should definitely be funded for the enormous impact it can make in the medical field. Stem cell research is perhaps one of the most controversial topics in modern day

Basal Cell Carcinoma Danielle Robbins Abstract This paper briefly describes basal cell carcinoma. Several scientific studies and articles are referenced to further present the causes‚ symptoms‚ tests‚ treatments‚ and prognosis of basal cell carcinoma. Also included in this paper are the different types of basal cell carcinoma and the populations that are affected. Basal cell carcinoma (BCC) is a skin cancer that starts in the epidermis (Medline Plus‚ 2012). The Skin Cancer Foundation defines

Cell Phone Abuse At the present day‚ with the development of IT and information industry‚ cell phone gradually plays an indispensable role in our daily life. Nonetheless‚ for the benefit of our concentration‚ health and social interaction around us‚ more attention should be paid to negative impact on the overuse of cell phone. According to a study of two hundred students at Sanford University revealed that 34 percent rated themselves as addicted to their phones‚ while 32 percent worried they

Sickle Cell Anemia‚ also known as Sickle Cell Disease‚ is a disease that causes the production of abnormal hemoglobin. The red blood cells (RBCs) carry oxygen to organs and tissues. Hemoglobin‚ a molecule in the RBCs‚ is a protein that attaches to the oxygen in the lungs and carries it to all parts of the body. Hemoglobin takes on the oxygen‚ and releases carbon dioxide‚ a process known as oxygenation. In the tissues‚ deoxygenation occurs where the processes is reversed‚ when hemoglobin releases

Composition I Essay 5 TEENS AND CELL PHONES: A RECIPE FOR DISASTER In 2008‚ CTIA and Harris Interactive conducted a survey of 2‚000 teenagers across the United States. The survey revealed that four out of five teenagers own a cell phone; they are considered a necessary accessory and a symbol of status among teens. Nearly half of kids who own cell phones get their first one between the ages of 8 and 12 years old‚ according to the Neilson Company. (1) While cell phones may be perceived as the key
