.... they help explain the how one species became another. "General lineage": This is a sequence of similar genera or families, linking an older to a very different younger group. Each step in the sequence consists of some fossils that represent certain genus or family, and the whole sequence often covers a span of tens of millions of years. A lineage like this shows obvious intermediates for every major structural change, and the fossils occur roughly (but often not exactly) in the expected order. However, usually there are still gaps between each of the groups. Sometimes the individual specimens are not thought to be directly ancestral to the next-youngest fossils (e.g. they ....

.... power plant would create more jobs. This would also benefit the government because less people would be collecting unemployment insurance and welfare. Thus adding to the amount the government could be spending on other things such as fixing highways, better healthcare, and more funding to school. Nuclear power is also a lot environment wise. Nuclear power requires a mere fraction of the space that is required to set up a solar, wind, or hydroelectric generating station which. This will allow more space for private landowners and will also keep land prices at a lower cost. Nuclear power is also a much cleaner operating type of fuel. The amount of waste produced is from a nu ....

.... is an endangered species and is only numerous in Florida, where there are breeding sanctuaries. The bald eagle makes its nest with a bulky platform of sticks in a tall tree, and normally has between 2-3 white eggs per season. The golden eagle has the scientific name of aquila chrysaetos and is named for its golden appearance. It is a member of the hawk family. It has a wingspan of six and a half to seven and a half feet, and can live to be thirty or more years old. The adult golden eagle is evenly dark below, or with a lighting at the base of its tail. An immature golden eagle shows a white flash in the wing at the base of the primaries, and a white tail wit ....

.... through the device. Most take their name from the type or des8igh of the flow control element. The body of the valve contains useful information referred to as bridge wall markings. This is specific information about the valve. One of the more common found in industry is a gate valve. A gate valve is typically operated in the wide-open, or completely shut position. This type of valve is used where flow rates are not restricted. Globe valves are the second most common valve used I industry. A globe valve places a movable metal disc in the path of a process flow. This type of valve is most commonly used in the throttling service. Ball valves take ....

.... They also have trouble relaxing and they often have insomnia. Many live from day to day with distressing physical symptoms such as trembling, sweating, muscle tension, stomach pains, or headaches that tend to worsen when they face even mild stress (Harvard Health Letter, 1998) In 1994, generalized anxiety disorder (GAD) became an identifiable mental disorder with a DSM-IV diagnosis. The diagnostic criteria for GAD are: A. Unrealistic or excessive anxiety and worry about life circumstances for a period greater than 6 months, during which this person has been bothered by these concerns for more days than not. B. The person has difficulty controlling the anxiety and ....

.... deduction of atoms throughout centuries. Nowadays, the atom is universally believed by people to exist as the result of scientific evidence. In contrast, ¡¥qi¡¦ is not believed to be a scientific phenomena and is considered a religious or superstitious belief. As a result, in order to demonstrate the existence of ¡¥qi¡¦ and make it conceivable by modern physicists, the use of the scientific method becomes the qi researchers¡¦ best tool. In addition, while qi and the atom were both conceived by ancient philosophers, the notion of the atom was better developed by scientists than the idea of qi. Therefore, by looking back at the historical progression towards a ....

.... the sexual orientation of a male is influenced by heredity due to the fact that “it directly examines the genetic information, DNA.” Furthermore, if there is a gene that influences an individual's sexual orientation, there is a great possibility of that trait being passed down from generation to generation. Experiments conducted led to the possible conclusion that the region Xq28 carries a gene influencing male sexual orientation. However, there are a few flaws to their interpretation of the results. Among them are stated in the article. A replication of the experiment is necessary, the separation of the particular gene has not been achieved, and the importance of ....

.... their ships ballast with wet sand taken from shores of Europe, a habitat where purple loosestrife thrived. Upon arrival in North America the ballast would be dumped overboard on the shoreline. By 1830 the plant was well established along the New England seaboard. Purple loosestrife seeds were also found in sheep and livestock feed that was imported from Europe during this period. This new organism was introduced to a new habitat free from traditional parasites, predators and competitors, purple loosestrife thrived in the environmental conditions and by 1880 was rapidly spreading north and west through the canal and marine routes. Purple loosestrife stands also ....
