... 1) Hearst was well aware of this and moved to ban Marijuana. Marijuana costs little to grow and can be made into cloth, canvas, and other high quality textiles. The use of Marijuana for textile production would have seriously hurt Dupont who had invested heavily in both paper production and the use of cotton. In 1936 Dupont joined Hearst and using scare tactics and effective lobbying were able to ban the growth, sale, and use of Marijuana.

Marijuana can be used to c ...

... is called embryogenesis. During the first week after fertilization, which takes place in the Fallopian tube, the embryo starts to cleave once every twenty-four hours (Fig. 1). Until the eight or sixteen cell stage, the individual cells, or blastomeres, are thought to have the potential to form any part of the fetus (Leese, Conaghan, Martin, and Hardy, April 1993).

The accumulation of fluid inside the morula, transforms it into a hollow sphere called a blastula, which implants itself into the inner lining of the uterus, the endometrium (Fig. 1). The inner mass of th ...

... of ovarian cancer, malignant progression, rapid emergence of drug resistance, and associated cross-resistance remain unresolved. Ovarian cancer has a high frequency of metastasis yet generally remains localized within the peritoneal cavity. Tumor development has been associated with aberrant, dysfunctional expression and/or mutation of various genes. This can include oncogene overexpression, amplification or mutation, aberrant tumor suppressor expression or mutation.

... of the most highly contested and objectionable topics of genetic power is the analysis of crime, violence, and impulsivity. Doubtless, most will agree that children are not born with a natural affinity for violence and crime; yet, new genetic studies are beginning down a long road of finding the hereditary basis for impulsivity. While these studies continue to search for the genetic source of aggression, child testing programs, drug manufacturers, civil rights activists, lawyers, and anxious citizens await the resulting testimony of the scientists. The social implications of the genetic search for aggressive tendency is seen by some as a great step forward, b ...

... by the microwave emissions from the antenna. Concerns have been raised about the type of mobile telephone that has the antenna in the handset. In this case, the antenna is very close to the user's head during normal use of the telephone and there is concern about the level of microwave emissions to which the brain is being exposed. Those telephones that have the antenna mounted elsewhere are of no concern, since exposure levels decrease rapidly with increasing distance from the antenna. Cordless telephones, which need to be operated within about 20 metres of a base unit that is connected directly to the telephone system, do not have any health concerns associate ...

... the re-legalization of marijuana today. Perhaps the most controversial aspect of the legalization debate is whether marijuana should be legalized for medical purposes. All drugs, both prescription and non-prescription, are federally 'Scheduled' by the DEA (Drug Enforcement Agency). A drug's scheduling under Federal law is determined “according to [its] effects, medical uses, and potential for abuse” (Claim V). In this classification system, marijuana is a Schedule I drug, grouped with heroin, LSD, hashish, methaqualone, and designer drugs. These are drugs having “unpredictable effects, and [causing] severe psychological or physical dependence, or death ...

... algae and other tiny organisms from the water and digest them within the cells of a special digestive gland. Intracellular digestion occurs even in some animals that consume large pieces of food; the prey captured by Hydra, for example, is partly digested in the coelenteron, a gut-like cavity, and the residue is completely digested in cells of the body wall. Scientists believe that intracellular digestion in organisms such as Hydra has evolved from such protozoans as amoebae and paramecia. In most higher animals digestion is completed not in the cell in the cavity of a digestive tract (the stomach and intestine). Animals with this type of digestion include crustac ...

... as a major influence on the children of America. Dr. Lonnie Bristow, AMA (American Medical Association) spokesman, remarks that "to kids, cute cartoon characters mean that the product is harmless, but cigarettes are not harmless. They have to know that their ads are influencing the youth under 18 to begin smoking"(Breo). Researchers at the Medical College of Georgia report that almost as many 6-year olds recognize Joe Camel as know Mickey Mouse (Breo). That is very shocking information for any parent to hear. The industry denies that these symbols target people under 21 and claim that their advertising goal is simply to promote brand switching and loya ...
