:29-11-16 HIV Prevention Strategy Challenge & Opportunity HIV stands for human immunodeficiency virus, which is the virus that causes HIV infection. HIV attacks and destroys the infection-fighting CD4 cells of the immune system. The loss of CD4 cells makes it difficult for the body to fight infections and certain cancers. Without treatment, HIV can gradually destroy the immune system and advance to AIDS.AIDS is the most advanced stage of HIV infection. AIDS stands for…

Sexually transmitted diseases (STDs), pertain to a group of diseases that are transmitted predominantly through unprotected sexual contacts. Besides intercourse, STDs are transmissible through contacts with infected areas, contaminated objects, or from pregnant women to the fetus. Sometimes people infected with STDs do not show symptoms, therefore, is unknown if sexual partners are infected. The causes of STDs are the infections with bacteria, viruses, fungi, mycoplasmas, and parasites whose…

started having mitochondria which is the “power house” of the cell and this is how eukaryotic cells has been created. Human body is composed of about 70 trillion of eukaryotic cells which starts with a fertilization of a female’s egg and male’s sperm. From the replication of the single cell called meiosis, a human is being created. However, no one knows which cell or cell group will become what part of the fetus’s body. Those cells are called stem cells. According to Ciram.ca.gov the stem cells…

under the premise of the rapid development of information technology, capital, goods, labor and other production factors to increasing the size of the flow and configuration, worldwide countries are deeper and deeper into the expanding, unified market system in the world, and closely interdependent relationship between the countries reached an unprecedented degree, economic globalization has become an inevitable development trend in the modern world economy. From the extension of economic…

Lord of the Flies starts off with a fine group of civilized British boys.…

willing to go in terms of stem cell research and cloning. Do people believe in the concept of cloning human cells or will there forever be a line that can never be crossed? Stem cell research offers great promise for understanding of basic mechanisms of human development and differentiation. It is vital in new treatments for diseases such as Alzheimer’s disease, diabetes and Parkinson’s disease. Human stem cell research also raises sharp ethical and political debates. The ethical and and policy…

great idea because this gives everyone a chance to being socially acceptable in life and a chance to live longer a chance to explore life to its fullest potential. “Blood has no nationality” this quote means that everyone bleeds, and it's all the same blood so why treat something so common in everyone so differently due to race or ethnic group.

Even though cardiovascular disease is common only in adult population, it is very likely that each age group including children and adolescents have the disease risk factors.…

a) What is the central theme of the article? Discuss the author’s perspectives and any other perspective mentioned.
