.... again so the fluorophore returns to its original state. This cycle allows the fluorophore to reliably emit a high yield of light with no outside influence other than the incoming photon. So GFP is basically a stable little (27-30 kD) green light bulb that can be tacked on to other proteins at either the N- or C-terminus without a distortion of its compact beta-can structure. Biochemists now frequently exploit GFP’s unique structural and physical characteristics to visualize various cellular activities. One such application of GFP is to understand the role of a hormone, T3, in the translocation of thyroid hormone nuclear receptors (TRs).* In t .....

.... will once again take a very large lead in speed. Thus I believe Intel builds better and faster processors than AMD. The first ever problems AMD had were with incompatibility problems that plagued their entire line of CPU's until the K6. These problems hurt AMD because nobody wanted a CPU that could not run 15% of the programs out. People wanted a processor that had programs optimized specifically for it, people wanted a computer with a sticker that said "Intel Inside" because they knew every program would run on it. If people wanted a cheap solution then they went with the low-cost AMD CPU and faced incompatibility problems with a lot of prog .....

.... to prove that in this report. People invent for many reasons. Some hope to make money, others invent to make life more convenient, and some even invent to satisfy their curiosity of their urge to create (7,364/5), but satisfying economic needs, was one of the main reasons for invention. The economic inventions needed were devices, machines, business, and industry-processes and products. The majority of economic inventions collaborate with one another; a lot of things were invented to make other inventions work. Another major reason people invent is to satisfy military needs. During war times engineers, scientists, and inventors are brought tog .....

.... and farmyard manuer. Inorganic manuer is Nitrogen, potassium or any other element necessary in the aid of plant growth. If one accidently digests inorganic fertilizer, he or she must see a doctor as soon as possible. One can get red eyes, itchiness, and or stomach problems. During World War 2, the government built many factories to absorb nitrogen gas from the air and to use them in explosives. Soon after the war, these factories were used to absorb nitrogen gas and to be used as a fertilizer. This method was inexpensive and farmers were now actually making a profit. By 1985, farmers used approximately eleven million tons of nitrogen a year. .....

.... burning regime on large tracts of land are increasingly being questioned (Lyons, 1985, 3). To an ecologist, fire can be treated as just one of the many factors in an environment. It compares with droughts, floods, hurricanes and other physical disturbances because of the direct impact it makes on organisms. Unlike these physical factors, however, fire as a disturbing force is itself influenced by the biota, particularly the plant community. Alteration of the vegetation by any number of factors can influence the nature of a subsequent fire. Fire has similarities to grazing as a force on vegetation because of such feedback effects (Whelan, 1995, 20) .....

.... of resistance is the improper use of drugs. When patients feel that the symptoms of their disease have improved, they often stop taking the drug. Just because the symptoms have disappeared it does not mean the disease has gone away. Prescribed drugs should be taken until all the medicine is gone so the disease is completely finished. If it is not, then this will just give the bacteria some time to find a way to avoid the effects of the drug. One antibiotic that will always have a long lasting effect in history is penicillin. This was the first antibiotic ever to be discovered. Alexander Fleming was the person responsible for the discovery in 1 .....

.... adversaries such as fungi, diseases, and frost so subsequently it dies. Around the 1970s the acid rain dilemma got worse, the acid rain has put trees in danger and now they are starting to die off. The effects of acid rain on a tree is shown if it has less foliage, yellow spots and produces many cones (Baines, 22). Secondly, acid rain damages the trees through the soil by releasing metals that harm them even further (Lucas, 72). Acid rain makes the trees lose their leaves, so when the trees try to regrow their leaves, buds come instead, this process is called a panic shoot (M. 15). Large land areas which used to be covered .....

.... the DNA replicates, and all of the preparations are made to be ready for to take place. The chromatis is coiled up and consists of loose threads. In prophase, the next longest stage, the chromatin becomes chromatids which later form chromosomes. They are attached to the centrioles by spindle fibers. The chromosomes are lined up in the center of the celll. The nucleolus and nuclear membrane disappear. In the next phase, metaphase, the chromosomes line up along the metaphase plate. The plate is the midpoint of the cell between the two centrioles which are located at opposite poles. During anaphase, the centrioles start playing tug of war with t .....

.... the damage caused to the economy by severely restricting energy use. Finally, his position assumes that the agreement will significantly reduce greenhouse gas emissions worldwide and will prevent global warming. Science Is global warming occurring? - According to Accu-Weather, the world's leading commercial forecaster, "Global air temperatures as measured by land-based weather stations show an increase of about 0.45 degrees Celsius over the past century. This may be no more than normal climatic variation...and several biases in the data may be responsible for some of this increase." - Satellite data indicate a slight cooling in the climate in the .....

.... to existing genes. Genes are the chemicals that determine the traits and characteristics of animals and plants. Every trait has one or more gene associated with it. Thus, natural selection provides the animals and plants with the best genes. Supporters of neo-Darwinism believe that natural selection operating upon random variation gave rise rise to all animals and plants. While the source of variation is random, the direction of evolution is not. In effect, natural selection removes chance, and it makes the theory of evolution plausible. If neo-Darwinism is correct then numerous small successive changes guided by natural selectio .....
