... Cigarette smokers are addicted to the nicotine in cigarettes just like a junkie is addicted to heroin or cocaine. When a person smokes a cigarette the body reacts immediately to the chemical nicotine. Nicotine begins to effect a smoker’s blood pressure, the flow of blood from their heart, the heart beat and breathing rate. Cigarette smoke also contains carbon monoxide, the same poisonous gases released from a car exhaust pipe. Carbon monoxide is a colorless and odorless, highly toxic gas that reduces the amount of oxygen that the blood can carry. Combined with the effects produced by the nicotine, it creates an imbalance in the demand for oxyg ...

... are capable of sitting upright and sometimes standing erect, and consequently their hands are freed for many manipulative tasks. Most have a short, relatively flat face without great prominence of the muzzle (excepting the baboons and drills).

Monkeys ar ...

... gas., the substance is held together by electrostatic forces between the ions. The tendency for these ions to be formed by elements is corespondent to the octet rule, when atoms react,, they tend to do so in such a way that they attain an outer shell containing eight electrons. The factors that effect the formation of ions are ionization energy, electron affinity, lattice energy. Figure 1 The transfer of electrons involved in the formation of (a) sodium chloride and (b) calcium fluoride. Each atom forms an ion with an outer shell containing eight electrons. For many elements, compounds cannot be formed by the production of ions, since the energy released in the ...

... Boyle to measure pressure were two: the manometer, which measures differences in pressure, and the barometer, which measures the total pressure of the atmosphere. A manometer is simply a bent piece of tubing, preferably glass with one end closed. When the liquid level in both arms is the same, the pressure of the sample of gas inside the closed end must equal the pressure of the external atmosphere since the downward force on the two columns of liquid is then equal. When the liquid levels are unequal, the pressures must differ. The difference in pressure can be measured in units of length of the vertical column of liquid. The mm Hg, or its modern version the ...

... on. Over eighty-five percent of the energy that powers the planet is derived from the burning of fossil fuels (Information 16). Fossil fuels contain impurities and these “impurities such as sulfur also burn and produce potentially dangerous oxides” which are released into the air (Burning www 1). Releasing these oxides into the air has many consequences including smog, which is the most noticeable of these problems. The hazy smog that hangs over us in the summer is actually ground level ozone; the most harmful pollutant of our air (Information 59). Pollutants of the air we breathe are very dangerous and cause many problems especially to people ...

... by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, or even decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers and lakes like the river Tovdal in Norway had not yet begun to die. However by 1976 local inspectors were noticing that many of the lakes were beginning to show signs of death. Fish were found dead along the banks of many rivers. As the winters ice began to melt off more and more hundreds upon hundreds more dead fish were being fo ...



The Effects Of Over-Population On The Earth's Water Supply

... population growth, however, the most appalling facts are that the planet Earth's water resources are depleted now. How can we allow the population to grow unchecked, when we know that even now, the Earth's water supplies are taxed to the limit? The subject of over-population encompasses many areas of study. Some examples are health, food, pollution and fresh water. The underlying link between all of these areas is water. The following four articles reveal that the water supplies that we all depend on are being used at an unsustainable rate. There is not enough fresh water on this planet for current growth rates to continue. The Public Broadcasting Company has posted ...
