... laying in April and may. Octopuses reproduce sexually, and have both male and female octopuses. Reproduction takes place as follows: The male octopus uses his tentacle to take a mass of spermatophore from within his mantle cavity, he then inserts it into the oviduct, in the mantle cavity of the female. This process occurs at depths from 20-100m and, lasts hours. With female octopuses receiving spermatophore up to 1m long. Female octopus seem to prefer larger males as mates and male octopus may mate with more than one female in their life span, however the male octopus only lives a few months after breeding, ...

... gases necessary for the support of plants and animals. I am the colorless air that is breathed in constantly. I am the plunging rain tah pours when the sun is shining, the white, damp snow that drifts in children's dreams, and the darting hail that prevents little boys and girls to attend school. I am the vivid part of life. I shield protection for those below me from the sun's intense heat. I am fed and drunk by those who go through hunger. As acid contained in the human body, I digest food and clean out wastes. I am a desperate hope for a cure, yet poison, slowly spreading in the air and along the land. I am the ...

... They hold a special place in polymer history, because their invention in a lot of ways was the beginning of an explosion in the invention of synthetic polymers which continues to this day. Cellulose derivatives are forms of cellulose, a polymer found in wood, cotton, and paper, which have been chemically altered. Scientists first started to make them in the second half of the nineteenth century, long before we really even knew what a polymer was. The very first came about when a scientist reacted cellulose, in the form of cotton, with nitric acid. The result was cellulose nitrate. Cellulose nitrate, also calle ...

... was constructed, and tested by the Manhattan Project, a big United States enterprise that was established in August 1942, during World War II. It was made by a group scientist including the physicists Enrico Fermi and J. Robert Oppenheimer, and the chemist Harold Urey, and was in charge by an U.S. Army engineer, Major General Lesle Groves. After the war, the U.S. Atomic Energy Commission became in charge of all nuclear matters, including weapons research. Other types of bombs were developed to tap the energy of light elements, such as hydrogen. In these bombs the source of energy is the fusion process, in which ...

... large dunes are visible from great distances throughout the area. Ironically, few geologists, except for McKee and Reiche, have studied the Coconino. The early work of these two, however, correctly identified the eolian origin of the Coconino. These Sahara-like dunes were part of an enormous desert that once extended north into Montana. During the last ten years, a number of studies on modern and ancient sand seas, or ergs, have increased greatly our understanding of eolian bedform dynamics. Additionally, we can describe trace fossils in the Coconino and relate them to the physical environments of deposition. This ...

... nor is the drug just used in one area of society. The Indian Hemp plant is found all over the world, including the US. There are three different types of Indian Hemp. They are Cannabis Sativa, Cannabis Indica, and Cannabis Rudderalis. These three plants vary in size and mood altering effect. The hemp plant has many uses and has been farmed for centuries. Marijuana can be taken in three ways, by eating, made into a tea, or smoking (the most popular). Smoking it can be done three ways, through a pipe, a joint, blunt. A joint is a rolled piece of paper that is twisted at the ends. A blunt is normal ...

... agendas in the halls of the United States congress. 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 questions it brings forth, the blanket of fear covering this remarkable technical miracle can be lifted. The first step to understanding genetic engineering, and embracing its possibilities for society, is to ...

... can carry bacteria that cause diseases like rabies and typhus, and can also contaminate food supplies. Insecticides are used by farmers who want to exterminate some of the many harmful insects that can carry disease. Insecticides are very widely used, not only on farms, but in residential areas in the form of products like Raid, and ant traps. are dangerous to our environment, but in most cases they help more than they hurt. For example, it is estimated that the food supply would reduce by forty to fifty percent without the use of on our crops. The FDA, EPA, and the Department of Agriculture try to ensure ...

... health problems including cancer, decreased fertility, and abnormalities in newborns. Evidence provided to support these claims of human and wildlife harm is largely from laboratory studies in which large doses are fed to test animals, usually rats or mice, and field studies of wildlife species that have been exposed to the chemicals mentioned above. In laboratory studies, high doses are required to give weak hormone activity. These doses are not likely to be encountered in the environment. However the process of bioaccumulation can result in top-level predators such as humans to have contaminants at levels many mil ...

... page" (Kunitz 123) of barrenness. Some pro-environmentalists, like Sioux medicine man John (Fire) Lame Deer, claim that the damage industrialized society has done to nature is both immense and nearly criminal , the result of greed. Lame Deer complains that the white men "have not only despoiled the earth, the rocks, the minerals, all of which they call ‘dead' but which are very much alive; they have even changed the animals, which are a part of us, part of the Great Spirit, changed them in a horrible way, so no one can recognize them" (Erodes 209). On the other hand, conservatives frequently label en ...
