... to sound better. To play these files you need a MP3 player. There are a couple different types of players out on the internet. The most common player for MP3s is a program called Winamp. Winamp can be found at Winamp.com. I personally like this player because it has a digital equalizer, which gives you more control over the sound of the music. This player reads the songs directly off the hard drive so there is no need for a disk, CD, or tape of any kind. This player also has a feature of a playlist where songs can be added or deleted. Which gives another reason to choose MP3s over albums. The easy access and the convenience of being able to control the mus ...
... until they are fully-grown. This way, animals and plants are recognized at an earlier state whether or not they will be useful in breeding. DNA fingerprinting also makes it easier to ensure that organisms are homozygous for certain, desirable traits, rather than relying on just the phenotypes which may actually prove to be heterozygous and can, therefore, pass on the traits which were intended to be removed. Even the knowledge of a single gene can have a major impact. Just by locating a single pathogen-resistant trait or adding or deleting a single gene can vastly improve the overall quality and value of an organism. One extremely important aspect of DNA techno ...
... to finding a job in Missouri, in the United States a whole employment is expected to increase 21% (Choices). After finding a job in the chemistry field that you will enjoy another quesiton arises, money. On hte average if you begin working at a entry level job witha bachelors degree your salary will be somewhere around $24,000 a year. If you start work with a masters degree you can expect about $32,000 and with a Ph.D. as mcuh as $60,000 ("Chemists") Research and development is the subcareer most chemist choose. In this subfield your primary goal would be to look for and use information about chemicals ("Chemists"). A chemists also spends a considera ...
... is holds up more because actual samples of fossils have been collected and scientifically tested using a method called carbon dating to determine the age of the fossils. Which can then be examined and placed along a timeline. The time periods show slight differences in bone structure showing what is hypothesized to be the human evolving. Evolving from what though? The theory of evolution states that creatures change overtime to suit their surroundings. This is called environmental adaptation. The more a creature can adapt to it's environment the greater chance it has of living and show an increase in population called survival of the fittest. A theory developed by ...
... in the structure of trees and other forest vegetation(4). The same occurs when forest stands are managed by humans. Unless future credible research indicates otherwise, effort should be made to manage a wide range of forest structures. Maintaining diversity would be best served by using a broader range of management tools. Those would include harvesting on federal land - not simply thinning - and increasing the commitment to old-growth attributes on private forest land through techniques such as retaining large trees and snags. As long as federal lands are substantially committed to providing late successional habitat, private forest land can be s ...
... process which needs to be completed perfectly, in order for the cell to divide and replicate normally. Very often a cell loses its regulation, and begins replicating out of control, that is it becomes cancerous. Abnormal cell growth is often known as cancer. During which, cancer cells do not respond normally to the body's control mechanisms. They often divide excessively, invade other tissues and, if unchecked, can kill the whole organism. Researchers studying cancer cells in culture have found that they do not respond to the normal signals that stop growth such as contact inhibition. They continue to grow until nutrients in the growth medium are exhausted. Othe ...
... when F.C. Steward cloned carrot plants from mature single cells placed in a nutrient culture containing hormones. The first cloning of animal cells took place in 1964. John B. Gurdon took the nuclei from tadpoles and injected them into unfertilized eggs. The nuclei containing the original parents’ genetic information had been destroyed with ultraviolet light. When the eggs were incubated, Gurdon discovered that only 1% to 2% of the eggs had developed into fertile adult toads. The first successful cloning of mammal was achieved nearly twenty years later. Scientists from Switzerland and the U.S. successfully cloned mice using a method similar to Gurdon’s, but r ...
... along on their flat little feet, eyes fixed intently on the ground, penguins appear myopic, inefficient and generally out of place. In fact the reverse is true. During a recent stay on the Falkland Islands, a Canadian researcher discovered that penguins are able to recognize individuals and navigate the rocky terrain on which they live quite well. Long of body and short of leg, they probably poke their heads forward as an aid to balance. And as for looking at the ground, they're merely-like us-keeping an eye on where they're going. The human eye is adapted for aerial vision, which is why scuba divers-or even you and I in the local swimming pool-must wear goggles ...
... relatively uncommon after the age of 50. After interviewing my grandmother, who is a special case Migraine sufferer, she told me that her Migraines began when she was seven. Often in school she would have the classic migraine symptoms- she would see only half of her teacher and bright lights and flashes up to 20 minutes before her Migraine began. These symptoms are called auras and once they are gone the Migraine begins. The Migraine itself can lead to vomiting, slurred speech, makes the sufferer sensitive to light and worsens when there is a lot of noise. The mechanism is not completely understood, but many women have their most severe attacks during or just ...
... what physics could teach him. This student, only having a rudimentary knowledge of physics, asks, "Can you give me a definition of physics?" The sage rolls his eyes back, and rubs his temples. He replies, "Big or small?" The student baffled by this, prompts again, "Um, physics?" The teacher noticing the ignorance in the room explains, "Physics is split into two major fields: Relativity (Einstein) and Quantum. Thus, they explain big forces in nature and small forces in nature, respectively. They are not cross- applicable." The student, still baffled, persisted, "But if physics explains nature, how is it that nature can be prejudiced in what applies? I mean ...
