The Platypus
.... own.
Home ranges house several burrows, that are located along the river bank. There are two different types of burrows, dwelling burrows, and nesting burrows. The nesting burrows are used for rearing young, and the other dwelling burrow is used by both sexes as a place to rest, sleep and eat. Burrows have a problem with maintaining a flow of air through them. If a platypus stays in a burrow for too long it will begin to use up its supply of oxygen. The nesting burrow has an entrance above wat .....

Valves
.... more common valves found in industry is a gate valve. A gate valve is typically operated in the wide-open, or completely shut position. This type of valve is used where flow rates are not restricted.
Globe valves are the second most common valve used I industry. A globe valve places a movable metal disc in the path of a process flow. This type of valve is most commonly used in the throttling service.
Ball valves take their name from the ball-shaped, movable element in the center of the .....

Deinonychus Antirrhopus
.... offensive weapon. Deinonychus is known from fossil remains found in south central Montana during the 1960’s. It was a carnivorous, bird-like creature with characteristics similar to that of a Velociraptor ( one of the stars from Jurassic Park ). This fearsome beast was quite a ravage hunter. The Deinonychus attacked its larger prey in packs and often were successful in doing so because of their menacing claw. By hunting in groups, members of the Deinonychus pack have brought down dinosaurs muc .....

Acid Rain
.... sulfur emissions from power plants in the United Kingdom are contributing to acid deposition in Scandinavia. Canadian emissions contribute substantially to acid rain in the northeastern United States, for example, and much of the sulfur falling in eastern Canada is believed to originate in the United States. In 1986 the U.S. National Academy of Sciences acknowledged that acid rain from U.S. sources had become a serious problem in the eastern United States and Canada. Although the Canadian government .....

The Landsats Satellites
.... Visible (HRV) sensors capturing visible and near-infrared radiance data with multispectral and panchromatic scanning capabilities. The multispectral mode captures data in three bands in the following spectral ranges: .50-.59, .61-.68 and .79-.89 micrometers. The three bands are co-registered and have a ground resolution of 20m. The panchromatic mode images data in the spectral range .51-.73 micrometers at a sampling interval of 10m.

The Periodic Table
.... functions of the atomic weights.
The periodic table provides an easy way to show the division of the elements into acid-forming and base-forming types. Those on the left are base-forming; those on the right are acid-forming. Those in between can be either. They have so-called amphoteric oxides and hydroxides that can act like acids or bases. The periodic table's arrangement also divides the elements into metallic and nonmetallic kinds. A distinction is usually made between most pure metals and no .....

UFOs And Alien Life
.... marsh gases, airplanes, lights of cars, birds, and many other objects as UFOs," (Kraske 22). Pranksters have also misled UFO investigation by doing actions that confuse and mislead humans. For example, they flash images of car headlights and city lights on the Earth. Pranksters also confuse people by tossing discs from tall buildings and taking pictures of spaceship models. One man was suspected of taking pictures of a realistic chicken-hatching machine. Human psychology has also played a role i .....

Cloning
.... human life. In the following paragraphs, he goes on to write about the "hasty legislation" that could possibly have negative long-term effects on the future of cloning because of the bad wording going into some of the laws. Many are afraid that the rich and famous might take advantage of the opportunity to generate copies of themselves. Nash points out that even though the possibility is there, the people who could grow full human clones "aren't going to be doing it."
Nash recognizes that by .....

The Polar Bear
.... their paws in this position helps them grip the slippery ice. Another specialized feature of its paws is that they have pads of dense fur on the bottoms. Polar bears are the only bears that have this feature. These pads help the bear retain heat and to grip the ice and provide better traction. Polar bears are fast movers. When on uneven ice the bear will “trot”, moving its legs on opposite sides in unison. It can trot at 12 to 18 miles per hour. When it is running, it can reach speeds of up to .....

Cloning, Right Or Wrong
.... or artificial insemination. Cloning could also make a copy of a deceased child for the parents. Also it would be a very useful tool for historians as people such as Hitler would be able to be recreated and studied to find out what their motivations were.
Besides from all these good points cloning also has bad points. The biggest problem with cloning on a large scale is the lack of genetic diversity. If everyone has the same genetic material, what happens if we lose the ability to clone? .....

Vivisection
.... they have rights too. Inmates should be able to do it if they want. The inmates should be asked that question by the judge when they are being sentenced for their crime.
I understand that there is another opinion to this debate. I can almost understand why they would believe in vivisection. The only time I believe it should be used is for patients dying of cancer. I still do not think it is right. We might not have some of the cures we have today without animal testing, although maybe we would. Ma .....

Greenhouse Effect
.... If this effect were to continue and grow, the earth’s population would be exposed to serious threats. Carbon dioxide is essential for plants who use it for photosynthesis, yet too much can lead to serious threats. The problem lies in the disruption of the balance between how much carbon dioxide plants intake, and what our population produces. If this natural filtering process is unbalanced, the atmosphere will receive too much carbon dioxide and other greenhouse gases. Once these gases form in the atmos .....

The Formation Of Rocky Shores
.... by successive flows of lava into the sea which have not had time to collect sediment.
Life on the rocky shores is separated into distinct zones that reflect the length of time each is exposed. At the highest point on the rocks is the black zone, marked by blue-green algae. This transition area between land and the marine environment is flooded only during the high spring tides. The algae, enclosed in gelatinous sheaths to resist drying, are grazed on by periwinkles, which are protected under tig .....

The Destruction Of Red Tides
.... a red tide very hard to predict or find.
Red tides often occur when fresh water runoff creates a stratified surface layer above colder nutrient-rich waters. "heavy rains might have helped the red tides develop by pouring fresh water and nutrients into surrounding sea waters," (New York Times: Sept. 19, 1996) Fast growing algae quickly strip away nutrients in the upper layer, leaving nitrogen and phosphorus only below the interface of the layers, called the pycnocline. Many swim at speeds of 10 meters .....

Botany And Botanists
.... or even sleep in the house that was once built, you can thank a botanist for it all.
Many people, such as myself, would wonder why someone would want to be a botanist. The main reason anyone can name is that plants have intrigued people for thousands of years. Plants are used for decoration, as well as our basic needs, such as: food, shelter, and even the air we breathe. Today, our world requires new needs for plants. Increasing human population is linked to gigantic environmental problems .....
