Introduction About 110 years ago, when McKinley was President of United States, the concept “Man on Moon” was an insignificant consideration to society and to the government’s budget. In present day, space constitutes a large portion of the 2011 government budget plan. President Barack Obama is predicting a manned Mars mission to orbit the planet…
What: The human genome project was a project that analyzed the chemical instructions that explain our hereditary features. This project also learned about heredities in the typical house mouse. The project also focused on the fruit fly and the round worm. The project also applies to cloning. When: The human genome project began in 1990.…
On April 20, 2010, an explosion occurred in the Gulf of Mexico that led to the sinking of the BP Oil Horizon. For exactly 86 days, approximately 4.9 million barrels of crude oil seeped into the Gulf of Mexico, leaving several harmful dioxins in its wake. This article intends to assess the potential for an…
In the article “Genetically Engineered Distortions”, there is much made over the misguided management of genetically engineered foods. The article opens by showing that there is a distinct split between two sides in terms of how to deal with the breeding of genetically engineered organisms. In the United States, eighty percent of cotton, corn, and…
Class Typical Effects Overdose Effects Depressants Alcohol Increases the activity of gamma-aminobutyric acid (GABA) By increasing an inhibitory neurotransmitter, alcohol dampens down neural firing Also decreases the activity of glutamate, a major excitatory neurotransmitter Person literally becomes less inhibited and feels euphoric An initial upper phase from the release of…
Appearance The Burrowing Owl’s upper body is coloured brown with white spots here and there. The Burrowing Owl’s legs are long and the fronts of the legs are feathered. The Burrowing Owl possesses a white facial disc and yellow irises. The look of each sex is not different. The Burrowing Owl is the only owl…
A cell is the basic unit of life, and all organisms on earth are made up of cells. The animal cell is a member of the Eukaryotes, which are complex multi-cellular organisms(Eukaryote). This type of cell is also enclosed within a membrane. Animal cells can come in different shapes depending on how they are covered…
Stem cells are highly controversial cells that have the potential to treat and even cure certain cell-related neurological diseases such as Parkinson’s disease and Alzheimer’s disease (Devitt, 2006, p 14). Stem cells are identified by two main characteristics: they are undifferentiated cells that can replicate through mitosis, and they have the potential to become specialized…
Environmental ethics is a part of philosophy that deals with the moral views between humans and the environment. It is concerned with the way humans impact their natural environment and it seeks to help people become more aware of how the earth is slowly deteriorating. Philosophers have made numerous attempts to reveal the moral status…
These processes occur on the inner mitochondrial membrane. The ETC consists of four main protein complexes: I, NADH dehydrogenase, II, succinate dehydrogenase, III, cytochrome complex, and IV, cytochrome oxidase. In each protein complex, are cofactors, which transfer electrons from NADH and FADH2 to O2. NADH donates an electron to complex I, releasing NAD+ and an…
Chemical Basis of Cellular Respiration Allows for the extraction of energy from sugars (i.e glucose) by slowing oxidizing it This process converts potential chemical energy into ATP (which can be used by a majority of reactions) C-H bonds (those found in glucose) are the primary energy bond found in organic molecules (i.e glucose, octane etc.)…
Darwin’s Five Observations More young are produced than survive Individuals vary in their characteristics Some characteristics are better than others These characteristics are inheritable Long periods of time are available Darwin’s Two Major Points Many species of organisms presently inhabiting the earth are descendants of ancestral species that were different from modern species The mechanism…
Aerobic exercise and fitness can be contrasted with anaerobic exercise, of which strength training and weight training are the most salient examples. The two types of exercise differ by the duration and intensity of muscular contractions involved, as well as by how energy is generated within the muscle. Initially, during aerobic exercise, glycogen is broken…
Parkinson’s disease is a progressive, neurodegenerative disease that occurs when the neurons within the brain responsible for producing the chemical dopamine become impaired or die. This disease progresses very slowly and most people who are ever diagnosed with it have been living with it for at least 20 years before severe symptoms start to show.…
Salt Poisoning Performed during the 2nd or beginning of the 3rd trimester of pregnancy A saline solution is inserted into the amniotic fluid surrounding the baby The baby breaths in this solution and painfully dies over a few hours from poisoning and dehydration The baby’s skin is burned off and the mother delivers the baby…
Toxicologists study poisons and conduct experiments on them to determine how safe or dangerous they could potentially be to animals, plants, and humans. Since chemicals are a vital part of everything we come into contact with, it is important to know the potential danger that is within our environment and what effects these dangers will…

Introduction Pigs, one of the most similar animals to humans, have been used to inform and teach students about the circulatory, respiratory, and digestive systems through a procedure called a dissection for many years. Pigs are similar to humans through the fact that they have skin, not fur or feathers, they are omnivores, and when…
Dehydration is a serious and potentially life-threatening condition that is caused by the lack of water needed for the body to function well. If not treated, dehydration can cause high body temperature, sleepiness, visual snow, dizziness, unconsciousness, hypotension (decreased blood pressure), headaches, nausea, paresthesia (limbs tingling), shriveled and wrinkled skin, dim vision, incapability to urinate,…
Purpose The purpose of this lab is to learn how to prepare a wet mound, to learn proper staining techniques and to examine human cheek cells and onion skin cells. Hypothesis It is predicted that all cells, no matter if it be plant or animal, will be amalgamated in large groups. Also that most of…
