.... The nervous system consists of a brain receiving information from eyes, antennae, and controls the whole body and 2 nerve cords containing ganglia fused together to control activities of the segment without the help of the brain. insect muscular system is made up of a few thousand samll but string muscles allowing the insect to carry objects heavier than it. The digestive system is basically a long tube where food enters the mouth to the crop where it is stored, gizzard where it is grinded, stomach where it is digested, then the undigested parts and wastes are moved to the intestine, colon then released at the anus. And in the .....

.... of the soil. A soil with a pH above 7.0 is called an alkaline soil, and will commonly kill plants. Mineral content, as mentioned above, is also a concern, and must be clearly monitored. After inspection, it is common for minor organic materials outside fertilizers to be applied, such as peat moss, ground bark, or leaf mold. It is after these steps that fertilization must occur, leading to a debate which has plagued gardeners and scientists alike: organic or chemical? Fertilizers, in both natural and synthetic breeds, are carriers of the primary and secondary nutrients that are found less often in even the most fertile soils. F .....

.... 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 with forests are now gone, dead or dying (Baines, 21). Around the 1980’s more than half Kotto 2 of the trees in Germany had signs of acid rain damage (Edmonds, 14). Now it is known that acid rain is one of the biggest contributing factors in the death and deterioration of nature. .....

.... absorbed by the leaves; the leaves orient themselves parallel to the sun’s rays. Plants that exhibit paraheliotropic behavior usually do so at midday, when the sun’s rays are perpendicular to the ground. This reorientation takes place only in leaves of plants that are capable of nastic light-driven movements, such as the trifoliate leaf of Erythrina spp. (Herbert 1984). However, this phenomenon has been observed in other legume species that exhibit diaheliotropic leaf movement as well. Their movement is temporarily transformed from diaheliotropic to paraheliotropic. In doing so, the interception of solar radiation is maxi .....

.... that is approximately 4 football stadiums filled to the top with oil. That is just every year…and this has been going on for more than a decade. In total, 45 million tons of oil in the past ten years that have been put into the oceans. There are several ways that oil ends up in the oceans. One method is through drilling accidents and another is through spillage from tankers and other transports. In 1990 alone, 1/8 of the total oil discharged "…occurred daily in the New York - New Jersey Harbor" (American Oceans Campaign). And this is only an eighth of the total oil spilled. Take a moment and just think about how much .....

.... has found a single cell living creature in a meteorite doesn't prove anything in my mind. Especially because of the fact that it has been on earth for 12 years when over this time the cell could have attached itself to the meteorite. Nobody knows enough about the subject to start telling the public that this is true, they should have never released it unless it were defiantly proven to be fact. NASA has a big name in the world, they should be more carefule next time. I just hope that whatever NASA had to say to the president in private isn't different to what they told the public We hear often that the media finds people that u .....

.... uses include electric signs,lamps,and lasers. Argon is the most abundant and most used noble on earth. It was discovered by Lord Rayleigh and by Sir Walter Ramsey in 1894. Argon makes up about 1.2 % of the earths atmosphere. It is found naturally in rock and in the air. It is used for electric light bulbs and floursent tubes. It is also used a lot in industry. Krypton a very rare noble was discovered by Sir Walter Ramsey and by Morris W. Travers. Traces of it are found in natural gas,hot springs and volcanoes but most of it is in the atmosphere. It is used for incadesent lights and it is used in high speed photog .....

.... beneficial insects that eat harmful species. Many pests that are attached to crop residues can be eliminated by plowing them underground. Simple paper or plastic barriers placed around fruit trees deter insects, which can also be attracted to light traps and destroyed. Weeds can be controlled by spreading grass, leaf, or black plastic mulch. Weeds also may be pulled or hoed from the soil. Many biological controls are also effective. Such insect pests as the European corn borer, and the Japanese beetle, have been controlled by introducing their predators and parasites. Wasps that prey on fruit-boring insect larvae are now be .....

.... microcephalus, and clubfoot. Mothers who smoke one pack a day during pregnancy have an 85% increased risk of having a child with mental retardation. Mothers that smoke during their pregnancy have double the chance of having a child with behavural problems. Another one of the biggest factors that disrupts fetal growth and development is alcohol. This is a very common substance abuse of pregnant women. Everytime the pregnant mother is drinking, her fetus is also drinking. The alcohol crosses the placental barrier, and goes directly into the fetus’s liver. The ethanol found in alcohol may impair the nutrient support of t .....
