How can animals facing extinction be helped using modern science? Identification and description of the problem Extinction is referred to as the death of the last organism of a certain species; thus ending those organisms altogether. However, since most species are globally spread out this is something that takes careful consideration of every fact such as ‘is there a possibility the organism may have has a chance of survival somewhere unexpected?’(Hawking, 2012) Biologists have been trying…

American Indians statistically suffer disproportionately from alcohol abuse compared with other racial groups in the United States. The factors that influence alcoholism among Native populations are still widely unknown, causing great health disparities in their people. To get an accurate perspective on alcohol use among Native Americans, examining different variants such as genetic and environmental factors would help determine if and why American Indians are predisposed to alcoholism. Recent…

A bird that looks like a giant vulture does not usually have charisma nor hold a place in people’s hearts. There is one bird that seems to have transcended this prejudice, inspiring enough passion to create panic at the idea of its extinction. This bird is the Gymnogyps californianus or better known as the California condor. When its numbers began to drop in the mid-20th century, a frenzy began in order to understand why it was disappearing and attempt to bring it back. With the dedication of…

BRCA1 and BRCA2 genetic testing, should everyone do it? Introduction Cancer happens when the cells in the body grow out of control and make tumors. This procedure is organized by biochemical in different parts of the body. (7) Breast cancer is the most common cancer among all the woman and about 5-10 percent of breast cancers are heritable. (9) Mutation in BRCA genes is responsible for 25 percent Inherent Breast cancer. Breast cancer is affected by so many risk factors. Every year about 233,000…

BRCA1 and BRCA2 genetic testing, should everyone do it? Shahrzad Eslamian Purpose: For a person with a positive mutation in BRCA1 or BRCA2, the chance of getting breast cancer increases by 50-60 percent.1 This causes concern for some women and makes them take a BRCA1/2 mutation test to make sure they are not carrying this mutation. In September 2015, a research from UCLA was published that indicated some debate over whether or not testing BRCA genes is worth the cost.4 This paper will be…

are roughly 46 to 72% heritable” (20). The article also gives information on the difference in genes between normal individuals and individuals with the illness. Based on the molecular genetic studies, studies have “failed to find an increase allele frequencies of dopamine D3 and D4 receptor genes” in individuals with anorexia compared to those who don’t have the disease (Berratini 23). Through this evidence, the author is able to conclude that genetic plays a huge role in the development of…

INTRODUCTION Cancer can be defined as a special kind of illness that occurs when the cells in a given part of a body begin to grow out of proportion than is normal. Currently, in the United States, this disease is the second leading cause of deaths. Human beings over the history have had tumors and remedies have been implemented, and others continue to be performed and studied over time (American Cancer Society, 2010). These methods of treatment include chemo-preventive methods and of late…
