.... Missile by using "redundancy of connectivity". This meant that in the event of a break in the network the server would re-route the information in an alternate path through a new technique called "packet switching". Packet Switching is a means of breaking up the message being sent into small packets which carry enough information to seek out its destination and sending them out separately towards the destination server. The message after being broken up would take separate routes to the destination and then be re-assembled by the computer at the server where the message was being sent. This was good because with more than one route for infor .....

.... of nerves or muscles, passage of current into the body, or use of interrupted current of low intensity to raise the threshold of the skin to pain. Studies suggested this therapy is applied to conditions such as ulcers, traumatic or burn wounds, osteoarthritis, and cancer. Electrical stimulation is simply the application of electrical pulses to the body, whether it is for function or therapy. The classical and common example is that of the cardiac pacemaker. The range of clinical uses of electrical stimulation has and is growing wider and includes: pain relief (often known as TENS - Transcutaneous Electrical Nerve Stimulation), maintaining .....

.... inside the cell as opposed to outside the cell. The further down the gradient, the lower the concentration of a substance. This brings into play the processes of diffusion, osmosis, and active transport, all of which involve only small simple molecules. Diffusion is the movement of a substance from a region of high concentration, to a region of low concentration of that substance. In other words, a movement down the concentration gradient. Osmosis is very similar to diffusion, however it involves the concentration of water. Osmosis, like diffusion, is a passive process, and does not require energy to occur. Active transport does require energy thou .....

.... risen regarding the praying mantis. Such questions include how many different species there are in the animal kingdom. Estimates range from 1500 to 2200 different mantid species WORLDWIDE. The most common figure given, though, is about 1800. The ways the Mantid's are classified in the Animal Kingdom. There is agreement that the collection of mantid species make up the Mantidae family of insects. The Mantidae family, in turn, is part of the order/suborder Mantodea that includes a variety of mantid-like species. But the existing literature does not reflect a clear consensus about what insect order Mantodea belong in. Some have placed Mantodea in .....

.... the victim of an related crime. In spite of the dangers presents,it is still in countless social cirles. penetraes all ages, educational, occupational, and socioeconomical boundaries. Each year it is estimated that ten percent of all deaths are related to abuse. Am astonishing fifty percent of all major automobile accidents, and murders are associated with . On and on the statistics point to the enormous dangers of , yet it is a legalized drug. As bleak as this problems seems to be on society as a whole, it is also rueful for the poor soul who is dependent. The life span of the ic is about ten years shorter than the non-drinker. The life .....

.... off from the original cell to become an independent cell. is most commonly known to reproduce asexually or reproduce self-fertile. Some produce sexually, but that is only a very minuet number. The most reproduction is created in substances containing much sugar. For some reason or another, this appeals most to the , causing it to grow at a rapid rate. Just like any other organism, in order for to survive they need to have a significant amount of nutrition. Unlike plants, lacks the chlorophyll needed to create its own food. It feeds on the sugar of many different resources to stay alive. Some of the most popular are different fru .....

.... Therest will be done automatically. This will be a safer, faster, and morecomfortable way to travel. Another new area, called "virtual reality" is currently being tested. This is away to simulate reality on a monitor. In order to feel this so-called realityyou have to wear special electronic glasses and an electronic suit. Fastened tothe suit are sensors, which send information to the main computer. Thiscomputer works with the data and displays them on the electronic spectacles. This is a technique which use three-dimentional views, therefore the scenery seems incredibly realistic. If you want to be a boxer, simply change thescenery on the main comput .....

.... came close to extinction. Most of the damage was done by poisons that farmers used to kill insects. The worst poison was DDT. By the time naturalists learned of DDT's effect on wildlife, it was almost too late. The American peregrine's scientific name is Falco peregrinus anatum. At one time, people called this falcon a duck hawk. That was a poor name, since falcons aren't hawks and they rarely kill ducks. The American peregrine was once found all across the eastern United States and southern Canada. In the west, the species was found from Mexico to California. DDT poisoning hit this subspecies the hardest. Even today, naturalists are still .....

.... breath. Whithout them, heterotrophs which need oxygen to survive would not live very long. The second reason is that autotrophs are the lowest food on the food chart. Without them many heterotrops would die from starvation. 3. Why did you put your syringes containing leaf material in the dark prior to illumination? The reason this was done was to make sure as little oxygen as possible was contained in the leaf material. This coused the experimrnt to run properly. If the leaf material was not placed in the dark, the dark reaction would not have occured using up all the oxygen. If there was still oxygen in the leaf material, the data collec .....

.... have been stored in different manners, but since several years new ways of disposing and storing these wastes have been developed so they may no longer be harmful. A very advantageous way of storing radioactive wastes is by a process called 'vitrification'. Vitrification is a semi-continuous process that enables the following operations to be carried out with the same equipment: evaporation of the waste solution mixed with the additives necesary for the production of borosilicate glass, calcination and elaboration of the glass. These operations are carried out in a metallic pot that is heated in an induction furnace. The vitrification of .....
