Like the glass in a greenhouse, certain gases that occur naturally in the atmosphere tend to trap the sun's heat. This natural "greenhouse effect" helps keep the Earth's average temperature at a comfortable 59' Fahrenheit. Without these greenhouse gases, the Earth would be about 0' F, like a deep- frozen snowball. The earth's clima...

Research on animals is important in understanding diseases and developing ways to prevent them. The polio vaccine, kidney transplants, and heart surgery techniques have all been developed with the help of animal research. Through increased efforts by the scientific community, effective treatments for diabetes, dipht...
is what we see. It can be thought of either as a particle, (the photon), or as a wave. The photon we can easily think of as a small dot travelling through space at the speed of light. Each photon has a particular colour or energy. But how do we think of light as a wave? For this we need to know that light is also an "Electro-magnetic field" --...
....and what are we g is caused by pollution containing sulfur dioxide, nitrogen oxide, and ozone ( SO', NOx, and O' ) is released into the air. These chemicals are absorbed into clouds and results in Acid Presipitation ( , Acid Snow, Acid Hail, Acid Sleet ). When the chemicals aren't absorbed into clouds, they can drift for miles and fall...
-. GLOBAL WARMING In 1992 the United States and nations from around the world met at the United Nations Earth Summit in Rio and agreed to voluntarily reduce greenhouse gas emissions to 1990 levels by the year 2000.

Did the whole human population originate from one of people or were we placed here and then improved or changed by an intervention? I believe that humanity on planet earth was created by evolution...
Genetic engineering is a laboratory technique used by scientists to change the DNA of living organisms. DNA is the blueprint for the individuality of an organism. The organism relies upon the information stored in its DNA for the management of every biochemical process. The life, growth and unique features of the organism depend o...

It all started back in 1953 with two men by the names of James D. Watson and Francis Crick when they discovered the double-helical structure of DNA. Little did they know they were opening the door to the creation of a perfect world. In 1986, the Human Genome Project, led up by the National Institution of Health(NIH), took a giant le...

Cardiac Pacemakers The heart is bestowed with a specialized system that automatically generates rhythmic control via the sinus node, located in the superior lateral wall of the right atrium near the opening of the superior vena cava. The specialized pacemaker cells dictate control of the rest of the heart through regular electrical impuls...
Mitosis, the process in which a cell undergoes nuclear division, is one of the four subdivisions of the cell cycle responsible for cell growth and reproduction. The first step in mitosis is prophase. In prophase the chromatin, diffuse in interphase, condenses into chromosomes. Each chromosome duplicates and has become two sister chroma...
