There are critics who disagree with the expenditure on space exploration, which they claim can better be used to solve earthly problems. However, they seem to forget that this is one of the fields which tests a man’s intellect. But, how does a common man draw benefits of space exploration? The advances made in the…
A lunar eclipse is an event during which Earth’s shadow prevents the sunlight from reaching the moon. When an eclipse occurs, the moon usually remains visible, but has a dusky red or coppery color, which results when Earth’s atmosphere bends some sunlight-mostly longer red wavelengths-into the umbra. A total lunar eclipse occurs when the moon…
Lunar craters are basically circular hollows on the surface of the moon. They are formed because of the impact of the meteoroids strikes. The smallest craters are microscopic pits, but the largest, the Aitken Basin, is nearly 21000 kilometres wide. Just an interesting fact, one of the most interesting craters on the moon is Copernicus.…
From Earth, one can look towards the night sky and observe that the moon appears to have areas that are lighter, and areas that are considerably darker. These dark areas are referred to as lunar maria, which are basically land basins on the moon in varying sizes. These basins were formed when hot, molten lava…
Induction: Induced & Permanent Charging Static electricity can be generated through: Friction, Conduction, INDUCTION Induction INDUCTION involves the movement of electrons in a neutral object when a charged object is brought close to the neutral object. The movement occurs WITHOUT DIRECT CONTACT between objects. Induced Charge Separation/ Temporary Charging When a negatively charged rod is…
Hydrologic Cycle: 97% of Earth’s water is stored in the oceans, evaporated then precipitated on land – some soaks in (infiltration), some flows over the land as streams (runoff), some evaporates back into the atmosphere and is transpired by plants, and some is stored in glaciers, but most returns to the oceans by streams Stream…
Reasons for Involvement Unrestricted Submarine Warfare: In January 1917, failed crops as well as a naval blockade caused severe food shortages in Germany. Desperate to attack back, Germany decided to establish its own naval blockade around Britain. They decided to sink any ship in the waters around Britain without warning, through the use of submarines.…
Down syndrome is a genetic and chromosomal disorder where a person has either half of or a full extra 21st chromosome. The disorder was first discovered by John Langdon Down, a British doctor, who first described the disease in 1866. Down syndrome is caused by a chromosomal abnormality which causes a replication of the 21st…
Purpose To see how the acceleration of a cart depends on the resultant force acting on the cart and the mass of the cart, and how this relation can be expressed in a single equation. We hypothesized that with a constant mass of the system (a decrease in cart mass) and an increased net force,…
Great Barrier Reef, Australia The Great Barrier is the world’s largest system of coral reefs. The Great Barrier Reef is made up of more than 2000 individual reefs and it extends 2000 kilometres. The Great Barrier Reef stretches 2300 kilometres along the Northeast coast of Australia going from Queenstown to Bundaberg. Ocean animals called coral…
The Panama Canal, Panama The Panama Canal is one of the greatest engineering achievements and most frequented waterways of all time. The Panama Canal cuts across the Isthmus of Panama and links the Atlantic Ocean with the Pacific. This canal was built in order to shorten the voyage between New York City and San Francisco…

What is Solar Debris? After birth of the Sun; debris was blown outwards Much of the debris eventually fell back into the Sun, if its trajectory was correct Other debris, has enough outward energy to break free of the Sun’s gravity, began to drift in orbit around the Sun Comets & TNOs Comets: Dirty snowballs…
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…

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…
