... "A wild flower is a plant that has always been it's own without any human intervention." Native plants "without assistance from a gardener in the area where they originated. Although all native plants are wild, not all wildflowers are natives" (Loewer 6). Where did the non-native flowers come from and how did they get here? "Probably the largest number of plants accidentally introduced in this country arrived in ships' ballast. Because the early merchant ships that sailed from Europe were empty of goods on the trip over, their hulls were loaded with dirt so that they would float properly. When they arrived in America, the dirt was removed and left onshor ...

... being done during Darwin’s findings that indicated there was a “gene” associated with certain characteristics. Mendel’s pea plants proved there was a way of artificially creating trends in color of flowers. This discovery led to modern genetics. We now know chromosomes carry valuable information that determines characteristics in living species. When you put these two discoveries together you really understand how animals have evolved to their currant state. When animals are born the have traits that help them live or inhibit their ability to live. If the die they cannot mate with other animals therefore they don’t pass on the traits that killed them. The anim ...

... 21 days there are 3 days where the ammonia spikes to a large amount and 2 days later on when nitrites spike generally. There are 2 types of filtration for fish tanks biological and mechanical. Biological is what I spoke about in the previous paragraph. Those bacteria grow best on objects besides gravel. That is why having plastic plants and other décor in the tank doesn’t just make the tank look nice but also give the bacteria a better place to grow. Mechanical filtration aids in biological filtration in two ways, the water is filtered through a medium that helps dissolve the ammonia and nitrites into smaller pieces easier for the bacteria to convert, and fi ...

... The U.S. produces over a billion pounds of phosgene (CG) per year for industrial uses; however, we do not stockpile this agent for military use. Perfluoroisobutylene (PFIB) is a toxic pyrolysis product of tetrafluoroethylene polymers encountered in military materiel (e.g., Teflon7, found in the interior of many military vehicles). The oxides of nitrogen (NOxs) are components of blast weapons or may be toxic decomposition products. Smokes, e.g., HC, contain toxic compounds that cause the same effects as phosgene does. The remainder of this chapter will deal solely with phosgene because it is the prototype of this class of agents; however, the principles of medical ...

... 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 occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as Carbon, Oxygen, and Helium are consumed. This chain reaction fuels the star for millions or billions of years depending upon the amount of gases there are. The star manages to avoid collapsing at this point be ...

... it’s the way that Hollywood uses a mix of fact and fiction in the series. This may have frightened many people into hating the Great White for it’s ferocity. It might have also been the size of the shark in the movie that’s kept thousands of people off the beaches and out of the water. Better yet, it could have been the overall storyline: A Great White shark with an eating disorder and a taste for human flesh. Perhaps that’s what is keeping vacationers from grabbing their trousers and snorkels. Over all, there have been 1026 attacks on humans by sharks in the last ten years. Only 294 of these attacks have been linked to Great White sharks. That’s roughly the n ...

... violet (UV) rays. Without this layer above us, many living things including humans could not survive. The ozone layer is currently depleting and the reason for this is believed to be caused by a few things. Deforestation, fertilizer use and fuel combustion are minor contributors to this problem while chemicals such as chloroflourocarbons (CFCs), halons, carbon tetrachloride, methyl chloroform, methyl bromide and hydrochloroflourocarbons (HCFCs) are the major contributors to the deterioration of the ozone layer. These chemicals have industrial halocarbons that break up into chlorine and bromine in the upper stratosphere when they react with the sun's rays. ...

... be aimed at three specific, vital areas: The creation of an aquatic medium, a terrestrial plateau and celestial ether that is conducive to human respiration. There are two planets from which to choose: Mars and Venus. Martyn J. Fogg authored what is regarded as a textbook of the future called Terraforming: Engineering Planetary Environments. I have chosen Fogg's book as my second primary source because it is the only book of its kind that addresses the question of terraforming in a non- science fiction context. The successful terraformation of a planet requires the synthetic development of a biosphere. The problems that present themselves are indigenous to the Geo ...

... ridges, small teeth, small eye sockets, broad, flat foreheads, large cranial volume (above 1200 cc.), low prognathism in the area of the lower face, and a high, vaulted shape in the area of the cranium. “Archaic” features in skull morphology include thick cranial walls, heavy supraorbital ridges, large teeth, large eye sockets, sloping foreheads, low cranial volume (below 1200 cc.), high prognathism in the area of the lower face, and a small, football-shaped cranium. The presence of various mixtures of these modern and archaic traits forms the basis for identifying a fossil as transitional modern/archaic in accordance with the multi-regional continui ...

... she would pass it on to her child because she can only pass on one of the two chromosomes. If a male has hemophilia, he will have normal sons and all of his daughters will be carriers of the hemophilia disorder because all he can pass on is the defective X-chromosome. Males mostly have hemophilia, but women can also have hemophilia. This is extremely rare though because two defective X-chromosomes would be needed. In fact, the first proven case of women having hemophilia was not until the 1950’s (Bornstein 89). Female carriers are also at risk. These women are known as asymptomatic carriers and may suffer excessive menstrual bleeding ...
