All About Ants (almost)

... Amber samples which scientists date in upwards of 100 million years old (The Ant Colony Œ89). These primitive samples have evolved into the 5000 to 10000 species known today which vary amongst themselves as widely as the numbers suggest (Social Insects Œ68). These remarkably adaptive creatures are found in some form on all continents and all habitats but the extreme arctics. Their success is manifested in the claim that at any time there are at least 1 quadrillion living ants on earth(Groliers Œ93). All species of ants are social. They live in organized communities or colonies, which may contain anywhere from a few hundred to more than 20 million individu ...

... technology with its social implications for human values and the future of work. It will argue that we have entered post modernity or post Fordism, a new age technological revolution, which profoundly effects social structure and values. Some issues that will be addressed are: elimination of work in the traditional sense, longevity, early retirement, the elimination of cash, the restructuring of education, industry and a movement to global politics, economics and world government. In particular this paper will suggest that the Christian Judao work ethic with society’s goals of full employment in the traditional sense is no longer appropriate, necess ...

... States government in 1942 to produce the first nuclear bomb. The official agency that produced the bomb was the Corps of Engineers’ Manhattan Engineer District, commanded by Major General Leslie R.Groves. He directed industrial and research activities at such sites as Oak Ridge, Tennessee, and Los Alamos, New Mexico (The World Book Encyclopedia 141). Here they designed to bombs that were later called “The Fat Man” and “The Little Boy”. There was later a movie named after the two bombs that showed how they were made and the experiences that came with making them. A worker was killed during the final stages of the Manhattan Project when a critical assembly of ...

... fulfill gender expectations. For example, Mark Zanna and Susan Pack (1975) had college women write descriptions of themselves for a tall, unattached, male senior whom they anticipated meeting. Those expecting to meet a man who liked nontraditional women described themselves as relatively nontraditional. Those led to think he favored traditional gender roles described themselves as more traditionally feminine” (Handout - Diversity and Community). I believe that one's immediate family, rather than society, has a greater influence on gender roles. For example, girls who group up without a mother or older sisters tend to be less feminine because all they have are ...

Most FAP patients develop cancer by the age of 39. Another form of hereditary cancer is Hereditary Non-Polyposis (HNPCC). HNPCC accounts for five to ten percent of all cases. HNPCC develops also at a young age but not as young as FAP patients. The actual cancer appears in the persons 40's. HNPCC is known as a "fast growing" form of cancer. Along with colon cancer HNPCC patients are also at a m ...

... few understand its effect of misdirection of the human mind. The first accounts of magic were recorded around 1700 B.C.

... temperatures for the amount of heat needed in a day. In order to generate "high grade" heat, intense enough to convert water into high-pressure steam which can then be used to turn electric generators there must be another method. The concentrated beams of sunlight are collected in a device called a solar furnace, which acts on the same principles as a large magnifying glass. The solar furnace takes the sunlight from a large area and by the use of lenses and mirrors can focus the light into a very small area. Very elaborate solar furnaces have machines that angle the mirrors and lenses to the sun all day. This system can provide sizeable amounts of electricity ...



Rubidium

... Rubidium is a fairly abundant element in the Earth's crust, there it is found in 310 parts per million (ppm). This makes it the 22nd most abundant element on Earth. It is found in many minerals, and brines, along with other elements. Seawater contains 0.2 ppm, twice the amount of Lithium found in the oceans. Traces are found in seawater plants and animal organisms. Very small traces of Rubidium are found in the leaves of tobacco, tea, and coffee, as well as some other plants. Rubidium is similar to lithium and cesium, which are found in combined forms as complex minerals. It is not found in a pure elemental (metallic) state in nature, but only as comp ...

... Mill., belongs to an extremely diverse and large family the Solanaceae. Often refered to as the Nightshade family, this family contains many of our commonly cultivated plants (potato, peppers, eggplant, tobacco, petunias, tomatillo) and various weeds (nightshades, jimson weed). It may have been this association with the nightshades which originally led people to believe the tomato to be poisionous. It was therefore fortunate that Miller changed the species name to esculentum which roughly means "edible". The common cultivated tomato belongs to the genus Lycopersicon. This genus exhibits a vast reservoir of genetic variability which remains largely underexploited. S ...

... are expected to rise causing more rain in some places and less in others. Another provider to the greenhouse effect is the use of CFCs. CFCs, or chlorofluorocarbon, are used in making plastics and in aerosol spray cans, refrigerants, air conditioners, and similar objects. Like carbon dioxide, the CFCs are trapping more heat in the earth's atmosphere. CFCs have also been blamed for ozone depletion. CFCs are suspected of breaking down ozone particles that shield us from the sun's ultraviolet rays. Too many ultraviolet rays can cause cataracts and skin cancer. A hole in the ozone has been discovered over Antarctic the size of the United States. The hole is ...
