.... Adults can grow up to 15ft (4.6 meters) but they usually only grow to about 10 feet. They weigh an average of 1300 pounds. Manatees live in small family groups sometimes up to herds of 15-20. After a gestation of up to 6 months, usually a single pinkish calf is born. Manatees ferquently communicate by muzzle to muzzle contact and when alarmed they emit chripy squeaks. The number of manatees has been reduced over the past several years due to heavy hunting for their hides, meat, and blubber oil. Some governments, including the United States, have placed the manatees under the endangered species list. One practical reason for this .....

.... of feeding on a species, the population of the species would start to increase. 3. It is seldom possible to count all the individuals in a given space. Explain one method by which biologists can study population densities without obtaining such data. Scientist barely ever count the amount of individuals in a certain area because it would take too much time. Instead of actually counting the number of individuals in an area they would compare it with other areas where they know the population of individuals. In this way they can roughly estimate the number of individuals in a certain area. 4. What might happen to a rabbit population in .....

.... Most matter on earth exists in three states: liquids, solids, and gas. All matter is made up of tiny particles called atoms. An atom is the smallest unit of matter that can exist and still be recognized. You and all the things around you are made of matter. Since we all live at the surface of the earth where the acceleration of gravity is relatively constant, it has been natural for us to confuse the concepts of mass and weight. To study the difference, we need to separate these two "parameters." We could either leave the earth's gravitational field so that we would have no weight, or create an experimental situation where weight is not a .....

.... schemes were tried and TCP/IP is what grew OUT of ARPANET, not what started ARPANET. During most of the seventies, the protocol was generally referred to as just the Network Control Protocol or NCP. The term Internet was probably first applied to a 1973 research program that culminated in a demonstration system in 1977. It demonstrated networking through various mediums, including satellite, radio, telephone, ethernet, etc. using packet switching. And this formed the roots of the Transmission Control Protocol and Internet Protocol (TCP/IP). But it was not until 1983 that all nodes on ARPANET were required to use TCP/IP to connect to i .....

.... exercise and eating regimen. I will explore sports supplements focusing on creatine and it's effect on the sport world. The first and most basic sports supplements are protein weight gainers. This normally comes in the form of powder and works best when mixed with milk. The main reason for taking extra protein is to gain weight and muscle mass. In today's athletics, whether it is high school, college, or professional, the athletes are getting bigger and stronger. Protein works the best when the athlete is on a strict work out regimen. Many sports supplements are a combination of herbs and proteins. A popular supplement of this .....

.... viruses, we are the invaders (Baddorf, Ourworld.compuserve.com)." Between the years of 425BC-430BC Athens' population was dramatically reduced when about 300,00 of its inhabitants died from some sickness. Some people now believe that this great plague was really Ebola. The first recorded outbreak of the Zaire string of the Ebola virus was in Zaire, in 1976. The doctors didn't know how to treat it and that meant that they didn't know how to contain it either. As infected people met in public places the virus spread. In Western Sudan, the same year, the Sudan string of the Ebola virus emerged with similar results. Both casts together .....

.... picks up or some kid crashes into the car with a bike. Both the wind and the kid's bike crashing into the bike are unbalanced forces. The car should start to move. The car might accelerate to two miles per hour. Now we would all assume that the car would come to a stop sometime. We assume this because it is true. It is true because there is friction between the tires and the road. The car now has inertia in uniform motion. Since there is friction, the car cannot keep moving forever because friction is an unbalanced force acting upon the tires. What if there was not any friction? The car would keep going forever. That is if th .....

.... an amount of water with hydrogen, nitrogen, and simple carbon compounds dissolved in them. These various elements were believed to either formed with the Earth or were picked up by the many meteoric collisions that immediately following the formation of our planet. The bulb had a heating unit under it to stimulate evaporation, then there was a smaller bulb that contained electrodes, simulating lightning and other static discharges, the evaporated water and gasses rose into this electrified bulb and were occasionally energized. The vapor then flowed into a condenser, and finally back into the simulated seas. The project was extremely si .....

.... a luxury. Comfort by definition is a condition of pleasurable ease or well being. By that definition there are endless numbers of object that could serve as a comfort. Take public transportation for example. The thought of having the train that takes us into the city is a commonly know option. Not always have people been able to choose public transportation as a method of getting to and from. Dating as far back as 1889 when the first method of public transportation was developed in Massachusetts. Before this the thought of having a bus or train run to the main areas of a community was absolutely unheard of. But in today’s society .....

.... the mechanical telegraph which required the use of a telescope and was much less effective. It encodes messages electrically, transmits them over facilities such as copper wire, coaxial cable, and fibre optics to their destination where they are decoded into their original form. Combinations of long and short bursts of electric current are sent through a circuit thereby encoding each letter of the alphabet. More efficient transmission facilities were developed as the mining industry developed. The discovery of electricity sped up the development of mining through electric lighting and better machinery and ventilation, which led to bett .....
