.... names of these three polyps are: dactylozooid, gonozooid, and gastrozooid. The polyps are the parts that: capture prey, digest prey, and reproduce. The dactylozooids have cells called nematocysts(3). The nematocysts release a toxin(4) into anything that they come into contact with. The gastrozooids then attach to the dead/stunned victim, and spread over it. They digest it, and transfer food to the rest of the man-of-war. Last, the gonozooids create other polyps. The means by which the man-of-war reproduces, however, is not yet understood. The fish Nomeus gronvii lives among th .....

.... also many other uses such as insulation and protection. They are also used in making cell membranes. They make it so that the cell can maintain it’s shape by keeping water and water-soluble compounds from passing through it. The lipids that are waxy are usually used to make protective coatings on the surface of plants and animals. Since a lipid is an organic compound it contains carbon. They also contain hydrogen and oxygen, but in some very complex chains there is also phosphorus and/or nitrogen. Lipids are made by the dehydration synthesis of glycerol and fatty acids. T .....

.... the primary ambition for scientists after Dalton, to find out the structure of an atom. In 1897, Joseph John Thomson discovered electrons. Using a tube, magnets and charged plates, he sent ray particles through various experiments changing the position of the charged plates. By changing the plates, he discovered he could also change the point at which the particles would hit a florescent screen at the end of the tube. He decided that the ray was made up of particles with a negative charge. He named these particles electrons. This discovery also showed that atoms had a s .....

.... on occasion may invade the home for cereals. In the United States, the Texas leaf-cutting ant, Atta texana , occurs in Texas and Louisiana. This ant is believed to cause a total yearly loss of $5 million in the United States (unison services. 1998). There are about 9,500 named species of ants. These ants are divided into 16 sub families and 300 genera, all which belong to the family called Formicidae, the family of ants (Hoyt. 1996). The leaf cutting ant belongs to the genus called Atta. There are fifteen different species of Atta and all are limited to the new world (Hol .....

.... claimed that cannabis destroys brain cells. However, several other studies found no structural or neurochemical atrophy in the brain at all. Furthermore, it should be noted that Heath's work was sharply criticized for avoiding safeguards of bias and reporting "changes" that occur normally in the mammalian brain. Wu et al. found a correlation between cannabis use and low sperm counts in human males. This is misleading because a decrease in sperm count has not been shown to have a negative effect on fertility and because the sperm count returns to normal after cannabis use has .....

.... to the extracellular matrix. This latter dystrophin-associated glycoprotein complex (DAGC) includes the extracellular proteoglycan, [Alpha]-dystroglycan, which binds to merosin in muscle fiber basal laminae, as well as a number of other integral and cytoplasmic membrane proteins: [Alpha]-dystroglycan; [Alpha]-, [Beta]- and [Gamma]- sarcoglycans (see Figure 1). The DAGC provides a physical link and, potentially, a signaling pathway between the extracellular matrix and the internal scaffolding of the muscle cells. Mutations in the Duchenne gene result in dystrophin deficienc .....

.... . Adult psychotic disturbances were noted in the early twentieth-century classifications of mental disorders (Nelson, Israel, 1997). The descriptions and classifications of these disturbances, however, were confusing and controversial. Kraeplin set the basis for modern classification. He used the terms dementia, a belief that progressive deterioration occurred, and praecox, meaning the disorders began early. Later the term schizophrenia was applied by Bleuer. He argued that deterioration was not inevitable and that psychological factors played a role. As time went on .....

.... it is taken into what is called the neonatal intensive care unit. In some of the smaller hospitals they aren’t equipped with the technology that is needed to keep the baby alive and the baby has to be transported to a bigger hospital, usually to a hospital in a metropolitan city in order to get the proper care. After the baby has been assessed for problems then it is watched closely for the next 48 hours. This is the most critical time for a baby . During this time the doctors can determine if the baby is going to have a long road ahead of them or if the baby is healthy and wil .....
