Science has always intrigued me. Therefore, being able to join the science honor society and explore its activities brings me euphoric joy. Joining the society would allow me acquire more knowledge about science. It would also provide me a platform where I can share my ideas on various topics in science. For my undergraduate degree, I plan on majoring in neuroscience as a stepping stone to medical school. I am curious about the brain and all its hidden potential that has yet to be explored by man. I am also interested in stem cells and their uses, and I would like to go into in-depth research about them for the science honor society project.

Water contamination is vastly becoming an alarming issue across the world. We rely on clean water to survive, yet right now we are heading towards a water crisis. Changing climate patterns are threatening lakes and rivers, and key sources that we tap for drinking water are being overdrawn or tainted with pollution (www.nrdc.org). Clean and plentiful water is the cornerstone of prosperous communities. Yet as we enter the 21st century, swelling demand and changing climate patterns are

To support the theory of continental drift is through topography, surveying the floors of oceans, charts of rock magnetism, and statistics on rock ages (Trefil & Hazen, 2010). At one time scientist believed that the deep ocean floors were flat; accumulating the sediment that progressively wore away from the prehistoric landmasses (Trefil & Hazen, 2010). However, they discovered steep-walled valleys and elevated highlands. This was evidences that just as the continents are transformed and are active, so to is the seafloor (Trefil & Hazen, 2010). The Mid- Atlantic Ridge, positioned in the central part of the Atlantic Ocean, is recorded to be the longest mountain range on this planet. Volcanoes, lava flow, and earthquakes are a source of

“The human history of the Yellowstone region goes back more than 11,000 years. From then until to the very recent past, many groups of Native Americans used the park as their homes, hunting grounds, and transportation routes. These traditional uses of Yellowstone lands continued until a little over 200 years ago when the first people of European descent found their way into the park. In 1872 a country that had not yet seen its first centennial, established Yellowstone as the first national park in the world. A new concept was born and with it a new way for people to preserve and protect

Structure and function in Biology is a broad concept that can be explored within a diverse range of topics across the subject matter. The following essay will be focussed mainly on the subject of Deoxyribonucleic Acid, or more commonly DNA. DNA is a highly complex, intricate and extraordinary macromolecule found within all living cells. DNA is a "biochemical noun" and can be defined as "...a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information." [Oxford Dictionary, c2016] DNA is found in the nucleus of eukaryotic cells, enclosed within a double membrane. Eukaryotic cells are multifaceted and require a high level of regulation to ensure smooth functioning. The double membrane of the nucleus allows gene expression, a key function of DNA, to be efficiently regulated.

Discovery inhibits the ability to embrace new beginnings and accept a sense of change whether it is found or forced upon an individual. The places you travel and the people you meet can emotionally revolutionize a self-discovery through unexpected but anticipated terms evoked from curiosity. ‘Swallow The Air’ written by Tara June Winch and ‘The Thing Around Your Neck’ written by Chimamanda Ngozi Adichie break the inhibitions of vulnerability, as their ideas represented through cultural contexts and values, lead to an overall self-discovery.

Adenosine deaminase deficiency is usually diagnosed between six months of age and a year. Prenatal and newborn screenings can discover the ADA deficiency.1 Usually newborns that have a family history of SCID are screened. However, as early identification of SCID can result in life-saving interventions before infections occur, many states have added SCID to their newborn screening panel. A test for ADA deficiency usually demonstrates the low number or absence of ADA activity in red blood cells. ADA deficiency is diagnosed when there is <1% of normal ADA catalytic activity in lysates of washed red blood cells from heparin or EDTA anticoagulated blood, reduced S-adenosylhomocysteine hydrolase activity and elevated urinary deoxyadenosine nucleotides in red blood cells and very low T, B and NK lymphocyte counts in peripheral
