... see a slightly different view of the apple. These different views tell you about the apple's depth -its form and where it sits in relation to other objects. Your brain processes this information so that you see the apple, and the rest of the world, in 3-D. You can look around objects, too -if the apple is blocking the view of an orange behind it, you can just move your head to one side. The apple seems to "move" out of the way so you can see the orange or even the back of the apple. If that seems a bit obvious, just try looking behind something in a regular photograph! You can't, because the photograph can't reproduce the infinitely complicated waves of light re ...

... high-tech society of today, some scientists and technicians researched the avenues of fiber optics. Fiber optics can be seen in telephone systems, in the military, in cars, in medicine, and in many other fields of study. For all industries and professions, "Fiber optics allow huge amounts of voice, data and video imagery to be transmitted instantaneously, allowing for photographic-quality images, interactive video conferencing and other business multimedia uses" (Inman News Features 1). It's becoming possible to transmit audio, video and data signals over great distances using these fibers of pure glass or plastic. Today, fiber optic technology has almost become ...

... for someone who is looking toward “bulking up” and increasing strength in a small amount of time. Steroids allow its users to recover more quickly from exercise than a natural athlete, so they can return to the gym sooner for another workout. So that means less work equals more muscle gain, compared to working out normally with no supplement. Who wouldn’t want that? Think about all the pain you wouldn’t have to go through doing all those reps. With a performance enhancing drug, you could do even less, get the same results and even better. Today more than ever, performance enhancing drugs and supplements are being abused. It is estimate ...

... they are classified as Animalia. And because relatively large bodies, this phylum has evolved efficient internal plumbing along with other specialized systems such as well developed open circulatory system, a complete digestive tract, along with excretory and nervous system, they are classified under the Mollusca phylum. It then goes under the classification of Cephalopod along with squids and chambered nautilus. From there it is ordered as Octopoda, (Family) Octopodidae, (Genus) Octopus. Then its species differ to differentiate one octopus from another. A common octopus's species is labeled as vulgaris. A common octopus's scientific name: Kingdom: Animalia ...

... a chatroom and conversing with fellow “Netizens”, and few clicks away from databases, essays, articles, and multimedia presentations on any entity whatsoever. For the same reasons that the World Wide Web is so valuable and popular, it is also bad and dangerous. You might be able to shop around for an airplane ticket and might decide to buy one over the internet, yet the minute you type in your credit card number you attract people in finding that number and using it without your consent. You might be amazed at how easy and helpful sending e-mails is, yet it is also easy for someone to send you unsolicited information, which you might not be intere ...

... as canals are constructed to guide ships through waterways to their destinations, the alimentary canal guides food as it travels through the human body. The whole canal is lined with a mucous membrane. Digestion begins in the mouth. Here the food is cut and chopped by the teeth. The tongue helps mix the food particles with a digestive juice called saliva, which is secreted in the mouth. Saliva moistens the food so it can be swallowed easily. It also changes some starches into simple sugars. It is important to chew food thoroughly to mix it well with saliva. Thorough chewing cuts food into small pieces that are more easily attacked by digestive juices. Food s ...

... and the body can not get enough oxygen to the muscle in order for them to perform their optimal potential. This lack of ability to get oxygen to the muscle is called oxygen debt and results in lactic acid being formed. Lactic acid is a waste product of anaerobic cellular respiration within the muscle tissue, which can cause muscle sourness that, usually, is felt after a hard or long workout. Fatigue usually sets in with the onset of lactic acid production. Oxygen is carried to the muscle by two delivery systems. Three percent of oxygen is carried in plasma and ninety-seven percent is in hemoglobin, the principal protein in erythrocytes (red blood cells). If ...

... meant "green twig" or "green shoot". Thallium does not have many uses. It is used in photocells because of the electrical conductivity of thallium sulphide. Thallium was originally used to help treat ringworm and many other skin infections. It was then limited because of the narrow margin between the benefits and its health risks. Thallium bromide-iodide crystals are still used as infrared detectors. Thallium sulphate used to be widely used as a pesticide and an ant killer. It was odorless and tasteless and worked well, but it was found to be too toxic. Thallium slats which burn with a bright green flame are used in flares and rockets. Thallium is the ...

... due to thickening of the blood vessels in the kidneys. Protein leaks into the urine and the blood is not filtered normally. Skin is greatly affected by diabetes Mellitus. There is poor blood flow to the skin which causes loss of feeling. Sores and deep infections called diabetic ulcers occur because of this. Pregnancy is affected by diabetes Mellitus. Many changes that take place during pregnancy make controlling blood sugar more difficult for a woman who has diabetes. Changes in the levels and types of hormones produced during pregnancy can cause insulin resistance, increasing the body’s requirements for insulin. Poorly controlled diabetes may endanger th ...

... of a small piece of real estate. Asteroids usually travel in groups and sometimes form asteroid belts that can wrap around an entire solar system. There are about 150 known asteroids that travel in a path near the earth, and they are actually called, "near-earth" asteroids. About 10 percent are bound to hit earth eventually. Asteroids ranging from fine dust, to house size rocks make up the belt around Saturn, and the belt on the outside of the orbit of Mars. These are pieces of larger rocks that were crashed into the remaining pieces after millions of years of crashes. Each ring system has distinctive features. Jupiter's rings are tenuous and made mainly of dar ...
