Anthopleura Elegantissima
1229 Words - 5 Pages.... One of the first steps in this section is collecting the anemones. Slowly sliding a spatula under the sea anemones, Francis dislodged them from the immense rocks to which they were attached. At the laboratory they were kept in glass bowls containing water from the sea and were fed periodically, exclusive of experimentation time. In case of any impairments from the collection process, the anemones were kept in these bowls for a few weeks before any of the experiments started. Only the most healthy anemones were used in the experiment. To free the anemones, Francis hit the bowl against a solid surface. To determine the sex of the anemones, they were severed and inspecte ....

An Investigation Into Electrical Resistance
1160 Words - 5 Pages.... conduct electricity to some extent. A good conductor of electricity, such as silver or copper, may have a conductivity billions of times as great, or more, as the conductivity of a good insulator, such as glass or mica.
Method
We were set the task of investigating the factors that come into play when determining the resistance of a piece of wire. We would be provided with the necessary apparatus needed to carry out the investigations. The basic setup would involve a circuit with a set of cells connected in series with an ammeter and the piece of wire being investigated, and a voltmeter connected in parallel with the wire. The ammeter is placed in series with the wire. ....

Telekinesis
3442 Words - 13 Pages.... teachers who can help develop this skill to some degree, but I do not know of any teacher who can help you develop so that you can use it 'at will' in our present third dimensional reality.
Teenagers are most wanting to develop and other higher skills such as telepathy, as they know they will use them in their lifetime. On an intuitive level they know we are shifting reality soon where this ability and others will be open to humans once again.
Many of the 'star children' --those who remember that they are connected to other worlds and realities--will try to tap into their higher gifts. 'Patience' is the name of the game. As the planet is shifting now into 4th dimensional ....

New High-speed Connections Will Change How We Work And Play
860 Words - 4 Pages.... and using our telephone line, dial in to our Internet Service Provider.
Because telephone technology is much older than the Internet, there have been limitations to how fast data can travel over existing copper telephone lines. Using an analog modem, data is translated from its digital form to an analog signal, to travel over the telephone lines. Once it gets to its destination, the data is converted back into its digital form. Line noise is a result of data being transmitted as an analog signal. The FCC imposed limitations, decades ago, to minimize the amount of line noise that was allowed. This law was imposed long before the PC ever existed. However, it directly ....

Black Holes
3663 Words - 14 Pages.... due to the planet's gravity will make it start to fall down again. If you threw the rock hard enough, though, you could make it escape the planet's gravity entirely. It would keep on rising forever. The speed with which you need to throw the rock in order that it just barely escapes the planet's gravity is called the "escape velocity." As you would expect, the escape velocity depends on the mass of the planet: if the planet is extremely massive, then its gravity is very strong, and the escape velocity is high. A lighter planet would have a smaller escape velocity. The escape velocity also depends on how far you are from the planet's center: the closer you are, the higher ....

Cystic Fibrosis
1879 Words - 7 Pages.... from our parents, is the number-one killer. Each day three people die from it. Despite this bad news, CF is no longer the nearly automatic death sentence it used to be. Improved treatments are allowing more than half of the people with CF to live into their mid-twenties, and some are already in their forties, fifties, and even sixties. It will be very important for you t frequently check with doctors for new medical advancements. More and More discoveries are made every day and one of them very well might be able to help you situation.
You cannot catch from someone who has it. It is not a contagious disease, cut a hereditary or inherited one. A child but be born ....

Cloning And Embryo Research
868 Words - 4 Pages.... of the cell cycle, they transferred 244 of the nuclei to the stripped-down eggs of Scottish blackface ewes” (Adler Par. 8). These nuclei had a full set of chromosomes, so fertilizing the eggs was not necessary. They then gave the eggs an electric shock to “initiate development” (Adler Par. 9). This was done after years of endless research. There was extensive research done in the area of embryo stem cells. Scientists have used such mouse stem cells for nearly a decade to create genetically altered mice (Travis Par. 8). Kaye Tucker of World Socialist Web Site writes, “These basic cells are present in the earliest stages of developing embryos and are able to de ....

The Prairie Dog: Friend Or Foe?
1768 Words - 7 Pages.... prairie dogs inhabiting only two percent of their range from Mexico to Canada. Biologists say that the resulting smaller, more fragmented prairie dog towns leave the animals vulnerable to disease and natural catastrophes. Populations are even limited on the land that is available. Current policies on National Grasslands and other federal lands typically limit prairie dogs to small percentages of available potential habitat.
Prairie dogs are essential to our prairie ecosystem. Many species dependent on prairie dogs for prey and habitat are diminishing in direct relation to the decreasing number of prairie dogs. Unlike other species, which have declined because of habi ....
