... and storing energy. When they store energy they make triglycerides also known as fat. There are also many other uses such as insulation and protection. They are also used in making cell membranes. They make it so that the cell can maintain it’s shape by keeping water and water-soluble compounds from passing through it. The lipids that are waxy are usually used to make protective coatings on the surface of plants and animals. Since a lipid is an organic compound it contains carbon. They also contain hydrogen and oxygen, but in some very complex chains there is also phosphorus and/or nitrogen. Lipids are made by the dehydration synthesis of glycerol and ...
... service is called @Home. The following is a current price list and is also available at www.coxrevolution.com. One important feature of Cox@Home is definitely the speed. Accessing the Internet is up to 100 times faster than a 28.8 modem because of the high bandwidth that is available through coaxial cable lines. A 28.8 modem can transmit data at a rate of 28,800 bits per second. Cox@Home cable modems can transmit data at 1,500,000 - 3,000,000 bits per second saving the user valuable time and unneeded boredom. Some factors that are beyond the control of the @Home Network can affect the speed of connection to the Internet. For example, the tremendous i ...
... people with epilepsy at the National Hospital for Paralyzed and Epileptics in London and proved Hippocrates' theory that epilepsy is a brain malfunction. Still, the 19th century health care systems in Europe isolated people with epilepsy and forced them to live in colonies away from society. Until as late as the 1950¡¦s, people rarely talked about their epilepsy and therefore hid the disorder from the public. While there are some recognized causes to epilepsy the vast majority of cases have no known cause. In cases where the cause is known it is called Symptomatic Epilepsy. Fewer than thirty-five percent of cases have known causes. The most common out of these ...
... kind of medical misfits there will be in the future, using this life-saving technology to their own personal, perhaps evil, advantages. Dealing with politics, Bioengineering has opened a whole new door pertaining to the military, whose use of it may create an ultimate destruction. The alterance of nature is un-natural, and creates an unbalancement in life. When we use this technology towards the wrong side, we may all be burned. You see, Biotechnology has the ability to altar what diseases we humans are susceptible to, and when scientists create something to eliminate immunities to diseases, it may result in a mass destruction of the evolved living being known as ...
... alone services such as telephone, telex, fax and data communications, ISDN is a network which can offer all these services as a package in which a user can talk, exchange data, faxes and other documents at the same time, instead of having to use different networks for these services. 3. What is Satellite Communications? This is the use of orbiting satellites to relay microwave transmissions from earth stations to the satellite an to re-transmit those signals back down to another earth station by means of microwave transmission. Cellular Radio At present there are two types of cellular radio systems in operation in Ireland. These are: 1. TACS This system is ...
... because acid rain kills the crops and fish we eat, ruins homes, and the acid can release lead in the pipes and the lead could go into our drinking water. It is hard to determine where acid rain may fall next, because the wind from a pollueted area could carry pollution to another area and the acid rain could fall there. The regions effected more by acid rain is large parts of eastern North America, Scandinavia, and central Europe. In alot of places acid rain isn't a probelm because some soils can neutralize the acid and it doesn't effect the crops. Areas more sensitive to acid rain is in the western United States most of Washington all of Oregon, sectons of Cal ...
... programs assess local conditions, including climate, crop characteristics, the biology of the pest species, and soil quality, to determine the best method of pest control. Tactics employed include better tillage to prevent soil erosion and introduction of beneficial insects that eat harmful species. Many pests that are attached to crop residues can be eliminated by plowing them underground. Simple paper or plastic barriers placed around fruit trees deter insects, which can also be attracted to light traps and destroyed. Weeds can be controlled by spreading grass, leaf, or black plastic mulch. Weeds also may be pulled or hoed from the soil. Many biological controls ...
... time greatly affects the impact that the pollutant will have on an ecosystem and population. Pollutants can affect both a population and an ecosystem. A pollutant on a population level can be either non-target or target. Target effects are those that can kill off the entire population. Non-target effects are those that effects a significant number of individuals and spreads over to other individuals, such is the case when crop dusters spread herbicides, insecticides. Next we look at population damage by a pollutant, which in turn has a detrimental effect on the ecosystem in several ways. First, by the killing of an entire population by a pollutant, it offsets the f ...
... into phylums and classes. ECHINODERMS Echinoderms are marine invertebrate animals of the phylum Echinodrmata, having external skeletons of calcareous plates just under the skin, no head, and a water vascular-system with tube feet. Echinoderms are radially symmetrical, lack specialized ecretory organs, and reproduce sexually. Echinoderms have the ability to regenerate lost or injured body parts. Starfish: Starfishes are free-living echinoderms that have a flat, star-shaped or pentagonal body, usually with a continuous disc that has five or more ray-like extensions called arms. Tube feet are located in an open furrow along the underside of the arms. These ar ...
... has a small head with large ears and a small mouth. The fur is soft and woolly and some can have stripes on them. The kangaroo's body is specially built for jumping. It has two long, powerful hind legs with four toes on each. The front legs are short and have five toes with claws. These paws are used to handle food. Most of it's weight it in the hind legs and tail. Kangaroos can jump across flat land up to thirty miles an hour. Even though it is quite timid, kangaroos can fight very hard. They use there paws to position an opponent, and then kick them with the powerful back legs. They can rip a dog or small child to death with a single stroke. Kangaroos ...
