.... experiments, I would need to obtain a number of bullfrogs from a natural habitat and place them in the lab made habitat, which would be similar to the one that they were removed from. Hopefully, the frogs will adapted to the new habitat and carry on as they did in their old habitat. Tampered bullfrogs such as those raised in labs or pets would not be used because the results would be inaccurate. The inaccuracy would be that these "tampered frogs" have been out of the wild for so long that they would not have the same range of frequency as those in the wild. I would first like to do this experiment on the male bullfrogs because of their d .....

.... It contains 29 protons/electrons (atomic number) and 35 neutrons. It's atomic weight is 65.39. Copper is an orangy, red metal that is found in ores as a solid form. It can be found in such countries as the United States, Chile, Zambia, Zaire, Peru, and Canada. The most important copper ores are the sulfides, oxides, and carbonates. From these copper is obtained by smelting, leaching, and electrolysis. It's alloys, brass and bronze, long used, are still very important; all American coins are now copper alloys; gun metals also contain copper. The most important compounds are the oxide and the sulfate, blue vitrol; copper compounds such .....

.... can hardly be noticed. Early symptoms of are very slight and often overlooked. They begin as simple things, such as tripping or dropping things. Twitching or cramping of muscles and abnormal fatigue of the arms and legs may soon follow, causing difficulty in daily activities, such as walking or dressing. In more advanced stages, however, shortness of breath or difficulty in breathing and swallowing ensue, until the body is completely taken over by the disease. Intellect, eye motion, bladder function, and sensation are the only abilities spared. Where and how this deadly disease originated is unknown, but it was first identified .....

.... radiation from the sun strikes ordinary oxygen molecules in the upper atmosphere." Lightening and sparks from motors also convert oxygen to ozone ( Stoker 1). The question about the destruction of the ozone layer revolves around whether human-made CFCs (chloroflurocarbons) used in air- conditioners and refrigerators are breaking it down. This is the ozone thinning theory: "CFCs release chlorine into the stratosphere... leading to ozone destruction and exposing the planet to harmful ultraviolet rays." Critics who discount the thinning theory still say that chlorine comes from natural sources like volcanic eruptions and does no permanent .....

.... rock for the tide to carry them out to sea. There are usually 1,000 to 50,000 eggs at a time. They are small larvae at sea where they molt several times in order to grow to reach the characteristics of a typical adult hermit crab. After reaching the adult larvae stage, the hermit crabs begin looking for a shell to live in. Once they mature and find a suitable shell, they come to live on land for the rest of their lives. Hermit crabs grow on land by shedding their exoskeleton. It takes about ten days for a hermit crab's skin to harden after molting. Shedding is a necessary part of their livelihood since they will grow back missing legs duri .....

.... overwhelming. Drinking water supplies are contaminated with runoff from nearby factories and even with pollutants from our own backyards. Demands of skyscrapers and condominiums wipe out our decreasing rainforests. This drudges wildlife from its natural home and into the havoc that is ours. Millions of acres of beautiful land are destroyed daily to satisfy the needs of mankind. But has anyone contemplated the needs of our wildlife? When their homes are incinerated, where do they run for shelter? Where will wildlife obtain its food and oxygen if the sources are gone? Not much is done about our destructive ways, we sit back and let mone .....

.... food, shelter, and clothing and constantly demanding more energy-using devices, the temperation to exploit land for human use without regard for consequences is great. Frequently, several forms of environmental change are responsible for the disappearance of species. For example, as tropical forests are cut down, primates have progressively smaller feeding and living spaces. They also become more accessible to hunters, who kill monkeys for food and trap many primates for sale as pets, research animals, and zoo specimens. Some animal species may move into human communities when their own are destroyed. Extermination of marauding monkeys, ro .....

.... 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. , droplet size, "sticking coefficient" for So2 on water, etc. What was being .....

.... what a Greenhouse is. A Greenhouse is a building made either of clear plastic sheets, or of glass. The sun's rays go through the glass, and heat up the air inside the building, and they have a hard time getting out. These rays get trapped inside the building, and continually heat the air inside, and even through the night the rays stay in and heat the air. The greenhouse is also called a "HOT HOUSE" because it gets so hot. The greenhouse effect is caused by gases such as carbon monoxide, carbon dioxide, and nitrogen escaping into the atmosphere. These gases get trapped in the ozone layer and do not let the suns rays escape very eas .....

.... pure aluminum at the Paris exposition of 1855. Aluminum the most abundant metallic constituent in the crust of the Earth. It is never found as a non-metal. It occurs most commonly as aluminum silicate or as a silicate of aluminum mixed with other metals such as sodium, potassium, iron, calcium, and magnesium. Charles M. Hall and Paul L. T. Heroult, independently and almost simultaneously found out that alumna, or aluminum oxide, would dissolve in fused cryolite (Na3AlF6) and then could be decomposed electronically into a crude molten metal. Uses- The given volume of aluminum weighs less than one-third than steel. Its high stre .....
