.... since 1959 have amounted to a golden age of solar system exploration. Advancements in rocketry after World War II enabled our machines to break the grip of Earth's gravity and travel to the Moon and to other planets. The United States has sent automated spacecraft, then human-crewed expeditions, to explore the Moon. Our automated machines have orbited and landed on Venus and Mars; explored the Sun's environment; observed comets, and made close-range surveys while flying past Mercury, Jupiter, Saturn, Uranus and Neptune. These travelers brought a quantum leap in our knowledge and understanding of the solar system. Through the elec .....

When Napoleon came into power, people became as violent and corrupt as their former rulers. This was known as the Reign of Terror. "England emerged from the eighteenth century a parliamentary state in which the monarchy was largely a figurehead," according to Pfordresher. (Pfordresher, 423). The Victori .....

.... form or combined with silver in small amounts. It is mostly found in the form of the sulfide. Mercury has many uses and is a very important element. A major use of mercury is in electrical equipment such as fluorescent lamps, and mercury batteries. Mercury is used in thermometers because the change in volume for each degree of rise or fall in temperature is the same. The use of mercury in the thermometer instead of alcohol was done by Gabriel Daniel Fahrenheit in 1714. It was also used in vacuum pumps, barometers, and electric rectifiers and switches. Mercury is used in a mercury-vapor lamps which are used as a source of ultrav .....

Some of the countries that are suspected of having biological warfare programs are unfriendly toward the U.S. Some of these countries are located in the Middle East and some are signatories to the Biological Weapons Convention.

.... cost around 700 dollars a ton. Some 10 million tons of deicing salt is used each year in the U.S. and about 3 million in Canada. Salt is used to keep snow and ice from bonding to the pavement and to allow snowplows to remove. When salt is applied to ice and snow it creates a brine that has a lower freezing temperature than the surrounding ice or snow. Salt is the ideal deicing material because it is: •the least expensive deicer •easy to spread •easy to store and handle •readily available •non-toxic •harmless to skin and clothing Salt pollution is broken into two main groups. Water, which includes the effects o .....

.... of feeding on a species, the population of the species would start to increase. 3. It is seldom possible to count all the individuals in a given space. Explain one method by which biologists can study population densities without obtaining such data. Scientist barely ever count the amount of individuals in a certain area because it would take too much time. Instead of actually counting the number of individuals in an area they would compare it with other areas where they know the population of individuals. In this way they can roughly estimate the number of individuals in a certain area. 4. What might happen to a rabbit population in .....

.... you are diagnosed with amebic liver you are very likely to also have an intestinal infection from the disease as well. This is not true for all cases though. Most cases in which both occur are in places of high temperatures and poor sanitation. Africa, Latin America, Southeast Asia, and India have many health problems associated with the disease. The most common way to get this disease is from one person to another. The other most common way is through unhealthy food and badly sanitized water. Not eating properly and excessive drinking will only worsen the disease. There are many ways that you can help prevent getting th .....

.... that receive these chemical messages. The key neurotransmitter in migraine is called serotonin (often referred to in the scientific literature as 5-HT or 5-hydroxytryptophan). If something interferes with the normal functioning (production, release, receptor docking, and/or re-uptake) of serotonin, that disrupts the normal functioning of the nervous system and can lead to various symptoms associated with migraine. The severe pain associated with migraine occurs when the mechanism that normally inhibits and/or mediates pain is disabled. There is no actual tissue damage occuring during a migraine attack. Instead, the pain results from a deran .....
