.... dark. Experimental design: I took the four seeds and divided theme into groups of two. I placed theme inside a paper towel which was inside a cup. I water both of the cups and placed one in the closet, where it was dark. The other cup I placed on the ledge, where there was a large amount of light at all times. Each day I provided the seed with the equal amount of water. In this experiment I had one control which was the plant in the dark. Results and conclusion: My hypothesis was correct. As you can see from the data graphs at first the seeds germinated at the same rate until the tip of the radicle broke trough and was visible. Afterwards the seed which was in .....

.... processes involved with the space phenomenon of the black hole. It will describe how a black hole is generally formed, how it functions, and the effects it has on the universe. In order to understand what exactly a black hole is, we must first take a look at the basis for the cause of a black hole. All are formed from the gravitational collapse of a star, usually having a great, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occu .....

.... signal when slapped against the water, as a support when is standing on its hind legs, and as a rudder while swimming. The body is plump, the back arched, the neck thick, the hind feet webbed, and all the digits clawed. The fur is usually reddish-brown above and lighter or grayish below. The eyes are small and the nostrils closable. The skull is massive, with marked ridges for fixing the muscles that work the jaws. The two front teeth on either jaw are like those of other rodents, wearing away more rapidly behind so as to leave a sharp, enameled chisel edge. With these can cut down large trees. It usually selects trees 5 to 20 cm (2 to 8 in) in diameter, but .....

.... that the DNA was acquired. Scientist long believed that once a cell became differentiated, that most of its approximately 100,000 genes shut off. Only a few genes remained active to allow the cell to perform its specific function of life. All efforts to reactivate the shut-off genes have failed. English researchers have came the closest by teasing frog body cells to develop into tadpoles. The tadpoles, however, never matured into frogs. The Scottish researchers have failed many times with sheep cells before their success, but the task was perfected and accomplished. Now this accomplishment has made it possible for the cloning of almost any mammal, in .....

.... 7% for those with some college education. Only the wages of college graduates are up. Of the fastest growing technical jobs, software engineering tops the list. Carnegie Mellon University reports, "recruitment of its software engineering students is up this year by over 20%." All engineering jobs are paying well; proving that highly skilled labor is what employers want! "There is clear evidence that the supply of workers in the [unskilled labor] categories already exceeds the demand for their services," says L. Mishel, Research Director of Welfare Reform Network. In view of these facts, I wonder if these trends are good or bad for society. "The danger of .....

.... In the simplest model of the atom, electrons orbit a central nucleus, composed of protons and neutrons. each electron carries one negative charge and each proton one positive charge. Neutrons carry no charge. Every atom has the same number of electrons as there are protons, so, on the whole, it is electrically neutral. The electrons have discrete kinetic energy levels, which increase with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into bands. In electrical conductors, these bands are continuous but in insulators and semiconductors there is an "energy gap", in which no electron orbits can exist, between the i .....

.... and therefore suffered greater from variation of abiotic factors, as a result, the organisms of the upper pool had to possess special adaptations to colonise the area. The lower rock pool generally contained different species which could out compete the organisms of the upper pool when in a more benign environment. The rock pools studied should both contain organisms specially adapted to live in the intertidal environment of the rock pools. The organisms need to be adapted to the microenvironment of the rock pool, as conditions are considerably different to those of a ‘normal’ marine environment. The rock pools spend some of their time completely submerged by .....

.... of the causation of schizophrenia has increased in the past several decades. Schizophrenia is a disease of the brain that is expressed clinically as a disease of the mind. Both its symptoms and signs and its associated cognitive abnormalities are too diverse to permit its localization in a single region of the brain. The working hypothesis shared by most investigators is that schizophrenia is a disease of neural connectivity caused by multiple factors that affect brain development. (3,4,5) Our current model of the causation of schizophrenia is very similar to that used to understand cancer. That is, schizophrenia probably occurs as a consequence of mul .....
