Genetic Engineering: A Leap In To The Future Or A Leap Towards Destruction

... arms to block its budding future. Spreading fear by misinterpretation of facts, they promote their hidden agendas in the halls of the United States congress. They fear that it is unsafe; however, genetic engineering is a safe and powerful tool that will yield unprecedented results, specifically in the field of medicine. It will usher in a world where gene defects, bacterial disease, and even aging are a thing of the past. By understanding genetic engineering and its history, discovering its possibilities, and answering the moral and safety que ...

Greenhouse Gases And Consequences

... it. The earth re-radiates much of this heat in the form of (invisible) infrared radiation. Infrared rays have a longer wavelength than visible light, and for this reason can be absorbed by certain gases in the atmosphere, labelled greenhouse gases. This absorption of heat warms up the atmosphere, which in turn radiates some of the heat back to the earth. Greenhouse gases include water vapour, carbon dioxide (CO2), methane (CH4), chloroflurocarbons (CFCs), Ozone (O3), and Nitrous Oxide (N2O). It all seems very straightforward: greenhouse gase ...

Solar Cells

... is necessary to go back to some basic atomic concepts. In the simplest model of the atom, electrons orbit a central nucleus, composed of protons and neutrons. each electron carries one negative charge and each proton one positive charge. Neutrons carry no charge. Every atom has the same number of electrons as there are protons, so, on the whole, it is electrically neutral. The electrons have discrete kinetic energy levels, which increase with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into ...

Down Syndrome 4

... with mental retardation in Surrey, England when he made the first distinction between children who were cretins and what he referred to as "Mongoloids." Down based this unfortunate name on his notion that these children looked like people from Mongolia, who were thought then to have an arrested development. This ethnic insult came under fire in the 1960s from Asian genetic researchers, and the term was dropped from scientific use. Instead, the condition became "Down's syndrome." In the 1970s, an American revision of scientific term ...

Global Economy And The Environment

... examples, where this has not been the case. In general, international agreements have its advantages, due to the fact that we can harmonize international standards. Therefore environmental concern is one of the key issues that the policy makers and MNCUs should set a high priority on. This is because growth and development is strongly correlated with environmental degradation. Furthermore, it is fair to say that the MNCUs are more likely to have a more harmful environmental impact from growth and development, as opposed to the lo ...

Earth's Climate And Seasons: ‘How Do They Relate?’

... sun, it is summer, and the sun’s rays are more direct there. But, at the same time it is winter in the opposite hemisphere, because it is further away, and the rays from the sun are indirect. They are indirect, because of the earth’s round shape. If you would take all ball, and shine a flashlight on it, there is no way possible to get the light to spread evenly over the entire ball. This is just like Earth and the sun. The earth’s shape makes the light amount about even, for example, at 40%S and 40%N latitude because the rays sort ...

Newton's First Law Of Motion

... unless an unbalanced force acts on it. When a body is at rest or in uniform motion this is called inertia. Let's say that someone parks a car on a flat road and forgets to put the vehicle into park. The car should stay in that spot. This state of being is called inertia. All of a sudden the wind picks up or some kid crashes into the car with a bike. Both the wind and the kid's bike crashing into the bike are unbalanced forces. The car should start to move. The car might accelerate to two miles per hour. Now we would all assume tha ...

Climatology

... general terms. Humid Equatorial climates, Dry climates, and Cold Polar climates are marked by certain prevailing characteristics that can be mapped such as continuous snow or deserts. One of the most popular classification systems is the Koppen Climate Classification system, which gives different climates three letters that describe that climate. The Koppen Climate Classification system is comparatively simple and is based on a triad of letter symbols. The first (capital) letter is the critical one; the A climates are humid and tropical ...

Nuclear Power

... nuclei of a Uranium atom splits apart, it splits into two atoms. Commonly the nucleus splits into Barium and Krypton; however, it can split into any two atoms as long as the number of protons equals the original amount of the protons found in the Uranium. In addition, a mass amount of energy is released along with two or three neutrons. It is these neutrons that can begin a chain reaction, each neutron that is given off could collide with another Uranium atom splitting it apart. Each of these fissioning atoms releases a very large amount ...

Addition Of Vectors

... together. An experiment was conducted to determine the difference between using graphical, analytical and experimental method in getting the resultant. A force table, weight holders, a set of slotted masses (200g and 249g), ruler, protractor, spring scale and triple beam balance were used. Each group has its own assigned mass and forces as well as a force table. Weight hangers were attached to two strings tied to the center ring of the force table, where two slotted masses, one 200g and the other 249g were hung according to their specified ...

Dangers And Destructions Of Floods And Hurricanes

... The length of time a coastal flood is dangerous is usually very short. It depends on how high the tide is which goes up and down twice a day. When the velocities of hurricane winds become severe the height of the waves become three or more feet higher than the previous high tide. Coastal floods can be caused by a number of things. Coastal floods can be caused by runoff, hurricane waves, tsunami (seismic sea waves), and hurricane rains. Coastal flooding can not only take part on oceans but it can also take part on lakes. Coastal flooding can ...

Freezing Point Of Naphthalene

... so that it is surrounded by the naphthalene powder but not touching the sides or bottom of the test tube. Use a clamp to hold the thermometer in place. 5. Ignite the Bunsen burner and using direct heat melt the naphthalene powder until it completely turns to a liquid. When the temperature reaches approximately 90o Celsius, stop heating. 6. Observe the change in temperature from 90o to 70o Celsius, recording the temperature at regular intervals, preferably 15 seconds. This data will be used to make a chart later. 7. Once the tempera ...
