Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine

Sickle Cell Disease is an illness that affects people all across the globe. This paper will give a description of the sickness through the discussion of the causes‚ symptoms‚ and possible cures. Sickle Cell Disease (SCD) is a "group of inherited red blood cell disorders."(1) These disorders can have various afflictions‚ such as pain‚ damage and a low blood count--Sickle Cell Anemia. The overall incidence of SCD is eight out of 100‚000 people. However‚ it is much more widespread in some people.

Cell Fusion Introduction: The fusion of cells is a fundamental biological event that is essential for a variety of developmental and homeostatic processes. The importance of cell-cell fusion during development and disease is displayed in a variety of biological processes including‚ but not limited to‚ fertilization‚ development of tissues‚ the immune response‚ and aspects of tissue regeneration due to stem cells (Chen and Olson‚ 2005). Fertilization‚ which is the fusion of sperm and egg‚

girls pursuing STEM related courses is evident starting in primary school and are due to an array of factors‚ including societal‚ familial‚ and cultural influences. Although‚ access to education for women and girls have improved globally‚ disparities in the access to a basic education still persist‚ thereby influencing the gender gap in STEM education. To demonstrate‚ a study conducted in the United Kingdom‚ found at ages ten to eleven both boys and girls equally engaged in STEM education (75%

Abstract: Renal cell carcinoma (RCC) is one of the most frequent urological malignancies in adults. It represents for aproximately %3 of all adult malignancies and accounts %90 of neoplasms arising from kidney. RCC often metastasizes to other organs‚ but very rarely to the head and neck region including maxilla and mandible. A 62-year-old man with metastatic renal cell carcinoma to the mandible was presented in this work. Key Words: Renal cell carcinoma‚ Mandible‚ Metastasis‚ Head and Neck

Introduction - sickle cell anemia The first suggestion that genes might provide the information for all proteins came from Linus Pauling’s lab at Caltech. He and his student Harvey Itano studied hemoglobin‚ the protein in red blood cells that transports oxygen from the lung to metabolically active tissues‚ like muscle‚ where it is needed. In particular‚ they focused on the hemoglobin of people with sickle-cell disease‚ also known as sickle-cell anemia‚ a genetic disorder common in Africans‚ and

Sickle cell anemia (SCA) is a genetic disorder that is hereditary. It affects the blood‚ and is caused when the hemoglobin in blood cells are deprived in oxygen from the proteins. These cause normal round blood cells‚ to have are rigid sickle shape. People affected by SCA have a higher risk of death‚ stroke‚ severe attacks‚ and severe rushes of pain. James Herrick discovered an anemia‚ and found bizarre sickle-shaped cells in 1910. A treatment for the disease was discovered in the 1920s by E. Vernon

look at the STEM job shortage. The proponents of STEM say that we have an acute shortage of STEM graduates. But is that true? One indicator is employment numbers. Let’s take 2012. In that year we had twice as many people with STEM degrees (immigrants and native born) than STEM jobs available. 5.3 million STEM jobs vs. 12.1 million people with STEM degrees. With less than half of the immigrants with STEM degrees were working in STEM jobs. Wages are good measure of labor demand. If STEM graduates were

making hydrogen fuel cell vehicles an everyday fact of life‚ with several test models set to debut over the next few years. Hydrogen fuel cells to power vehicles are desirable‚ experts say‚ because hydrogen is a renewable fuel that can be used to create electricity to run cars. A chemical reaction between oxygen and hydrogen produces the electric power‚ and when pure hydrogen is used‚ the only emission from the tailpipe is harmless water vapor. Many people are asking‚ “Why fuel cells?” The gasoline engine

economy have been thriving‚ jobs in science‚ Technology‚ engineering‚ and math (STEM) have not had a major growth within the 21st Century. As a result‚ the lack of growth in STEM has had a major impact on the economy. Because of the high level of thinking and problem-solving skills needed to understand STEM subjects‚ the people who work in these fields end up having a high income. Another factor that contributes to the STEM are the number of men that pursue these careers. Over the past few years‚ many
