... became hereditary. Later scientist disproved this theory when more was learned more about genes and how they work. 50 years later Darwin came up with a theory that most scientist believe it to this day. this is called the theory of evolution. His book was called “The Origin of Specie.” Alfred R. Wallace, came out with a theory that was almost identical to Darwin’s theory. Darwin’s theory was much more developed and better known. For example Darwin pointed out that farmers would take certain qualities from two different plants and mix them together and it would produce the desired plant. He believed this happened in nature a ...

... cooled. Several million years later, it condensed into galaxies. The universe has continued to expand, and the galaxies have continued moving away from each other ever since. Today the universe is still expanding, as astronomers have observed. The Steady State model says that the universe does not evolve or change in time. There was no beginning in the past, nor will there be change in the future. This model assumes the perfect cosmological principle. This principle says that the universe is the same everywhere on the large scale, at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can ...

... short was indicated in the current from fuel cell 3, which was supplying power to cryogenic oxygen tank 2 fans. Within several additional seconds, two other shorted conditions occurred. Electrical shorts in the fan circuit ignited the wire insulation, causing temperature and pressure to increase within cryogenic oxygen tank 2. When pressure reached the cryogenic oxygen tank 2 relief valve full-flow conditions of 1008 psi, the pressure began decreasing for about 9 seconds, at which time the relief valve probably reseated, causing the pressure to rise again momentarily. About a quarter of a second later, a vibration disturbance was noted on the command module acc ...

... disorder that affects one in approximately 2,500 females. Females normally have two X- chromosomes. However, in those with Turner's Syndrome, one X chromosome is absent or is damaged. OTHER NAMES Depending on the doctor, Turner's Syndrome may be diagnosed with one of the following alternative names: 45 - X Syndrome, Bonnevie- Ulrich Syndrome, Chromosome X, Monosomy X, Morgagni-Turner-Albright Syndrome, Ovarian Dwarfism, Turner Type, among others. SYNDROME CHARACTERISTICS A reduced growth in height is the commonest visible characteristic of the syndrome, (the average adult height is 4 feet 8 inches) and may be the only sign before puberty. Their body pro ...

... affect the oxidation of sulfur in the atmosphere, everyone with a different success. The second possibility is the reaction of sulfur dioxide with the atmosphere. Here are a few equations: 1. (2So2+O2 2So3 2) So3++120 H 2So4 The second reaction takes place very quickly. Therefore, the making of So3 in the damp atmosphere is assumed to be the lead to the formation of sulfuric acid. Phase two: the aqueous phase, sulfur dioxide occurs as three species. [S {iv}] [So2{aq}]+[+1S03-] +[So32-] This process occurs by a twofold process. 1) So2 (aq) H++H S o3- 2)H so3-(aq ) h++ So32- The establishment of the equilibrium is dependent upon such things as ph. , d ...

... with the crystals until1943. (LSD can be absorbed through the skin.) Hoffman then sent LSD around the world to be tested and investigated to find medical uses. Lysergic acid deviates were found to relieve migraines and control postpartum hemorrhage because it causes veins to contract, but also caused gangrene of the limbs, and so further experimentation with the drug was abandoned. In the late 50's, however, LSD was used by the CIA as an interrogation drug for spies. However, it was proven to be unreliable and was later replaced with other interrogation drugs. LSD comes in the forms of crystals, liquids, tablets, gelatins, or blotting squares. The squares hav ...

... Here a look at the facts sheds some very dark light. In 1950, there were 2.5 billion people, while today there are 5.8 billion. There may well be 10 billion people on earth before the middle of the next century. Even more significant, on an ecological level, is the rise in per capita energy and material consumption which, in the last 40 years, has soared faster than the human population. “An irresistible economy seems to be on a collision course with an immovable ecosphere.” Based on these facts alone, there is grave reason for concern. Taken further, it is even more frightening to note that, while man has affected the environment throughout his stay on ...

... the organism depend on its DNA. The segments of DNA, which have been associated with specific features or functions of an organism, are called genes. Molecular biologists have discovered many enzymes, which change the structure of DNA in living organisms. Some of these enzymes can cut and join strands of DNA. Using such enzymes, scientists learned to cut specific genes from DNA and to build customized DNA using these genes. They also learned about vectors, strands of DNA like viruses, which can infect a cell and insert themselves into its DNA. Scientists started to build vectors, which incorporated genes of their choosing and used vectors to insert these genes ...

... 4 feet. The bottlenose is closer to 10 feet. The killer whale, which is also considered a dolphin, can grow to be 30 feet long. The pilot whale is also considered a dolphin. Dolphins were once hunted by commercial boats for the small amount of oil that can be extracted from their body. This oil is used to lubricate small parts in watches. Cheaper oils have been found, so dolphins are not hunted for this reason anymore. Dolphins can be caught in tuna nets by accident. Since dolphins have to breath at the surface they drown in tuna nets. It is estimated that 4.8 million dolphins were killed in tuna nets from 1959 to 1972. Under pressure from animal rights activis ...

... his father, Robert Waring Darwin II, didn't think so. "Darwin had a youth unmarked by the slightest trace of genius." (Rachels,7). This didn't stop Darwin, though. He never lost this curiosity throughout the years. At the age of 18, he made a very important discovery about flustra, which is "1. That the ova of the Flustra possess organs of motion and 2. That the small black globular body hithero mistaken for the young Fucus lorious is in reality the ovum of the Pontobdella Muricata." (Rachels,7). In the early 1800's, a group of naturalists led by Captain FitzRoy, were planning an overseas trip, which they called the Voyage of the Beagle. They invited Darwin alon ...
