Extra Sensory Perception

... that there is indeed a sixth sense; ESP. Extra sensory perception, or ESP, is defined as a way of receiving information without using one of our five senses. The study of ESP is a part of a science called parapsychology. This is also called psychical research, or psi for short. Besides ESP, there is another branch of psi communication which includes the phenomenon in which an object seems to be moved by the mind alone. The mover does not touch the object which can be living or non living. This is called psychokinesis or PK. There are ...

Global Warming--is It Getting Warmer

... are burned. Methane is emitted during the production and transport of coal, natural gas, and oil. Methane can also come from the decomposition of organic waste and livestock’s waste (cow poop). Nitrous oxide is emitted during agricultural and industrial activities, as well as during burning of solid waste and fossil fuels. (http://www.epa.gov/globalwarming/). Light energy comes through the earth’s atmosphere and is absorbed. It is then transformed into heat energy at the planet's surface. This heat energy then radiates upward ...

The Beaver

... 25 cm (about 10 in) long and serves as a warning signal when slapped against the water, as a support when is standing on its hind legs, and as a rudder while swimming. The body is plump, the back arched, the neck thick, the hind feet webbed, and all the digits clawed. The fur is usually reddish-brown above and lighter or grayish below. The eyes are small and the nostrils closable. The skull is massive, with marked ridges for fixing the muscles that work the jaws. The two front teeth on either jaw are like those of other rodents, wearing awa ...

Venomous Creatures Of The West Pacific

... delivery system and use their toxin for protection only. They store their toxin in their meat or skin. If someone or something eats the animal, the predator may get sick or even die. Most marine creature fall into two categories invertebrates (animals without backbones) and vertebrates (animals with backbones.) These animals are further broken down 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 wa ...

Migraines

... of the nerve cells (neurons) so that the nervous system is no longer able to constantly maintain the natural balance that the nervous system is intended to maintain. Neurotransmitters are chemicals that nerve cells (neurons) use to communicate messages to each other. Receptors are special areas that receive these chemical messages. The key neurotransmitter in migraine is called serotonin (often referred to in the scientific literature as 5-HT or 5-hydroxytryptophan). If something interferes with the normal functioning (production, release, ...

The Measurement Of Gas Exchange In Blue Gouramis

... 21% oxygen (Campbell 1997). This concentration is high enough so that terrestrial animals do not have any problems obtaining sufficient oxygen amounts for cellular respiration. Aquatic animals, however, obtain oxygen from a different aquatic respiratory medium---water. The dissolved oxygen concentrations in an aquatic environment is much lower than the 21% oxygen concentration available in the atmosphere (Barstow et al. 1999), hence special problems pertaining to the acquisition of sufficient amounts of oxygen arise for aquatic organ ...

The History Of White-Tailed Deer In Kentucky

... in Kentucky and they succeeded. They regulated the hunting seasons and the amount of game allowed to kill. Today we have an abundance of deer in Kentucky, we have about 450,000 deer. The white-tailed deer breeding season in Kentucky runs from October through mid January, reaching its peak in November. Most fawns are born in June, following a seven month gestation period. Newborn fawns will weigh about four pounds at birth. Deer offspring are cared for and may remain with the mother until the next spring. Fawns retain their spots until mi ...

Coral Fish

... circling and/or nose-to-belly nuzzling may signify that spawning is about to take place. Any of these performances are usually accompanied by dramatic changes in the patters or intensity of colors of the fish. Males and females tend to advertise their sex and availability through vibrant colors. This sexual dimorphism is most evident in such reef residents as groupers. The color patters change predictably from the "juvenile: to the "initial" subdued pattern of small adults to the "terminal" pattern in the largest adult males. Th ...

Endangered Species 2

... worldwide. Along with fieldwork, Chinese scientists have worked continuously to improve the success rate of captive breeding of the Giant Pandas. This has proved to be quite a challenge, all the more so since pandas are only receptive to breeding for a very brief period in late spring or early summer. Research efforts have, however, paid off. Since 1991 natural mating has resulted in eight births at the Wolong centre. In addition to experience gained over the years at Wolong, the recent success of births can be attributed to improved cooperat ...

Oil Spills And Pollution

... the oil had virtually been swept back into the ocean on its own. An Alaskan official reported that he watched the film crews scatter to less attractive areas of the beach as news media arrived to cover the Exxon people’s taping.14 As bad as the Valdez disaster was, Exxon made five billion dollars of revenue during the 1989 operating year. Of that, they spent three billion over the next several years on the clean up. During the cleanup, Exxon employed the assistance of 12,000 people and 1,385 ships and planes. They recovered a little ove ...

Evolutionism

... things had evolved from each other and there was no God. The theory was sort of a dream or manifestation without any original grounds for belief. Over time more and more people looked into and they developed possibilities of how it occurred. Many theories were developed, but someone always disproved them. Recently with the discovery of genetic mutation and a new understanding of genes and DNA, the evidence supporting evolution has greatly increased. Charles Darwin was one scientist who helped to increase the evidence supporting ...

The Geiger-Muller Tube

... copper cylinder with a negative charge. A rigid wire with a positive charge runs down the center of this cylinder. The voltage across the wire and cylinder is kept just below the point at which a spontaneous discharge, or spark, occurs. When a charged particle or gamma ray enters the tube , it ionizes a gas atom between the copper cylinder and the wire. The positive ion produced is accelerated toward the copper cylinder by the potential difference. The electron is accelerated toward the positive wire. As these new particles move toward ...
