Sexually Transmitted Diseases
Sexually Transmitted Diseases 05-16-97 A major question facing many teenagers is whether or not to have sex. A result of having sex is contracting sexually transmitted diseases. Sexually transmitted diseases, or venereal diseases affect 10 to 12 million Americans each year. (Daugirdas 75) In the United States, sexually transmitted diseases strike an average of one person every 1.5 seconds. (76) About half of STD patients are under the age of twenty-five. (Landers 45) Nearly 2.5 million teenagers

Bacteria
Bacteria Bacteria are often maligned as the causes of human and animal disease (like this one, Leptospira, which causes serious disease in livestock). However, certain bacteria, the actinomycetes, produce antibiotics such as streptomycin and nocardicin; others live symbiotically in the guts of animals (including humans) or elsewhere in their bodies, or on the roots of certain plants, converting nitrogen into a usable form. Bacteria put the tang in yogurt and the sour in sourdough bread; bacteria
Antibiotic Resistance In Bacteria
Antibiotic Resistance In Bacteria
Antibiotic Resistance In Bacteria For about 50 years, antibiotics have been the answer to many bacterial infections. Antibiotics are chemical substances that are secreted by living things. Doctors prescribed these medicines to cure many diseases. During World War II, it treated one of the biggest killers during wartime - infected wounds. It was the beginning of the antibiotic era. But just when antibiotics were being mass produced, bacteria started to evolve and became resistant to these medicin
The Digestive Systems
The Digestive Systems
The Digestive Systems The digestive systems works on nutrients taken from the environment, breaking them down into simpler products, and then absorbing the products together with water and salts so they can be used in metabolism. The individuals of all species contain many different protiens or carbohydrates in the cell walls of bacteria, chitin in the external skeletons of arthropods, and so on and foreign proteins or carbohydrates are rarely incorporated unchanged. They are usually first broke

Forensic Science: Proper Crime Scene Techniques. The word Forensic is derived from the Latin forensus, meaning of the forum.1 In ancient Rome, the forum was where governmental debates were held, but it was also where trials were held -- the court house. From that, forensic science has come to mean the application of the natural and physical science to the resolution of matters within a legal context2. Forensic Science can be viewed as a tripartite structure consisting of 1. Collection: which

In humans, plague occurs in three forms: bubonic plague, pneumonic plague, and septicemic plague. The best known form is the bubonic plague and it is named after buboes, or enlarged, inflamed lymph nodes, which are characterist

Aplastic Anemia
Aplastic Anemia Aplastic anemia is a disease of the bone marrow? the organ that produces the body's blood cells. Approximately two thousand people in the U.S. are diagnosed each year with aplastic anemia. The symptoms of aplastic anemia are fatigue, bruising, infections, and weakness. Although these symptoms are much like those associated with leukemia, aplastic anemia is not a form of cancer. In patients with aplastic anemia the bone marrow stops producing, or produces too few red blood cells,

The Ebola Virus A virus is an ultramicroscopic infectious organism that, having no independent metabolic activity, can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid, either RNA or DNA, surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication, and the host cell provides the necessary energy and raw materials. There are more than 200 viruses that are know to

The Life of LOUIS PASTEUR Louis Pasteur was born on December 27, 1822, in D?le, a small town in France. He grew in a humble family and his father was a tanner. He graduated in 1840 from the College of Arts at Besancon and entered the prestigious Ecole Namale Supervieure, Paris, to work for his doctorate degree. He chose for his studies the then obscure science of crystallography, which was to have a great influence on his career. Pasteur entered the scientific world as a professor of physics at
Active Transport
Active Transport
Active Transport Since the cell membrane is somewhat permeable to sodium ions, simple diffusion would result in a net movement of sodium ions into the cell, until the concentrations on the two sides of the membrane became equal. Sodium actually does diffuse into the cell rather freely, but as fast as it does so, the cell actively pumps it out again, against the concentration difference. The mechanism by which the cell pumps the sodium ions out is called active transport. Active transport require

Nitrogen was discovered by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist, Antoine Laurent Lavoiser about 1776. Nitrogen is a colorless, odorless tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can be compressed into
