... we have to understand the main brain functions. “The human brain is a marvelously complicated organ; it has to be, for it controls every waking and sleeping activity, every conscious and unconscious thought and need and process that we engage in.” (Harry Sands and Frances C. Minters, 1977, p.2) The brain consists of nerve cells or neurons. Each neuron has an electrically charged part. It receives electrical signals from other neurons, and passes them to others. All the functions of the brain depend on electrical signals that are send from one neuron to another. The normal brain generates an electrical r ...

... The Big Bang. At the present time there are two theories which are used to explain the creation of the universe. The first theory is the infamous Big Bang Theory, which will be detailed later. The second is the Steady State Theory. (Weinberg, 1977) The later hypothesis was created to replace the common belief that the universe was completely static. The expansion of the universe was discovered in 1929 when Edwin Hubble discovered that every galaxy in the universe was moving away from each other, this meant that the universe was expanding. Hubble found the movement of the galaxies by using a phenomenon known as ...

... which withstands grazing animals and occasional fires. Producer: An autotroph organism (grass). Consumer: Organism that eats producers (caterpillars, bison). Primary consumer: Organisms that eat consumers (chicken, meadowlark). Secondary consumers: Organisms that eatprimary consumers (praire felcon, eagle). Decomposers: Organisms that uses nutrients from dead plants and animals, it starts the chain over (bacteria). Say that an organism was removed from the web, such as a caterpillar. Though it's not the only grass eating organism it would still mess up the web. Say you put the bison in its place, that part would ...

... time analogue sound is modified or retransmitted, it loses quality. Digital audio uses a binary code representation of the continuous stream of data. Once in this form, it can be modified in any way without any degradation of the original sound. One can make copies of copies with digital audio, and the hundredth will be exactly like the first. The great advantage of digital audio with respect to radio is the possibility of listener interactivity. Currently, any interactivity is limited by the inability of the individual talk to the other end of a radio transmission chain. When one switches stations on our radio ...

... 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 three accepted types of ESP, clairvoyance, precognition,and telepathy. Clairvoyance is the extra sensory perception of events that are taking place at the exact time of the p ...

... INTRODUCTION "Anemia can be defined as a decrease in the oxygen-carrying capacity of the blood caused by low hemoglobin concentration" ("A Practical Guide", 1). "Cells in the body require oxygen to fully utilize fuels. The oxygen is transported from the lungs to tissues throughout the body via red blood cells. Oxygen binds to hemoglobin, a specific molecule within each red blood cell. This molecule consists of heme, which is a red pigment, and globin, which is a protein. If the amount of functioning hemoglobin is ...

... ammonia and methane. Usually these cores are about the same size as earth possibly a little larger. It is also possible that Uranus and Neptune’s core is a liquid instead of a solid. also have about the same rotational characteristics and all have rings around them. Jupiter, the first of , reigns supreme throughout the solar system. Named after the Roman god Jove, the ruler of Olympus; Jupiter is the fifth planet from the sun and is also the largest planet in the Earth’s solar system. It is 318 times more massive than Earth and is two thirds of the planetary mass in the solar system. Jupiter’s surface, ...

... use drugs, you would realize that the question is not as simple as it may appear. To answer this question objectively, you need to consider how the body and mind work together. The simple act of daily living creates countless demands on ourselves both emotionally and physically. Stresses we encounter determine the demands on which we place on our mind and body. To free themselves of this stress, some people chose recreational drugs to put them in another frame of mind. The body, in most instances, craves a minute amount of the chemical to balance its desires; however, the mind says, "If a little is good, a lot is ...

... is in danger of extinction. Once 50,000 nenes inhabited the islands. Now there are less than 200. The sugar cane fields in Hawaii became the breeding grounds for rats. Farmers released mongooses to kill the rats. They also began to eat the nene chicks and eggs. Roy Blackshire runs a program that places captive born nenes into the wild. This program, once a success, is now causing chaos in the nene population. A single pair of nenes were taken from the wild and bred in captivity. Later two more birds were added. The chicks were released into the wild and the program continued. Though there are several dozen nenes re ...

... spurning and love triumphant. And take note: these are not the imaginings of some Disney screen-16 writer. Decades ago Konrad Lorenz, a famed Austrian naturalist, made detailed studies of Greylags and afterwards showed no hesitation in using words like love, grief and even embarrassment to describe the behavior of these large, social birds. At the same time he did not forget that all romance - animal and human - is tied intimately to natural selection. Natural selection brought on the evolution of males and females during prehistoric epochs when environmental change was making life difficult for single-sex s ...
