Exploring The Mind
Words: 967 - Pages: 4.... from 1 to 4 years of age have a very limited knowledge of how to conduct themselves in society. They have not had time to learn the social standards of their time. So with this limited knowledge, children will consistently react to situations in a similar way that can only be explained by an instinctive nature. Have young children changed their behavior since the 1700's? I suppose any child from any culture at any time in history would cry when it was upset, physically take whatever it wanted, need a certain amount of love and attention, and also be interested in exploring things outside of it's bounds. I feel that all of these instinc .....

Plants In TKM
Words: 1033 - Pages: 4.... by giving them something to take their mind off of life for a while. Garden Geraniums may reach the size of a bush in warm, dry climates (Garden Geranium 1). Again, the bright colored flowers make any bouquet of flowers complete. It is very hard to get any Geraniums to grow in short and cold growing seasons, like in the Pacific Northwest. It was very easy to grow and pick the beautiful flowers in the south. Wisteria is in the legume family of woody, climbing plants. The best know Wisteria are Chinese, but American are just as good. Most people use them for crawling things to go over doorways and porches. Porches in the south were a ve .....

Cd Roms
Words: 1257 - Pages: 5.... magnetic. If you open one up it will look like egular record player. The needle is what writes the information onto the hard drive. The needle writes by the magnetic force that pushes it down on to the disk. Once it is on the hard drive , whenever you turn on your computer the information is always there for you when you need it.
A CD:ROM looks like a music compact disk , but they are not that much alike. First a CD:ROM has a lot more information than a regular compact disk. A CD:ROM has audio as well as visual information. Second a CD:ROM stores more data in it. Third if you put a CD:ROM in a compact disk player the compact disk play .....

Human Origins
Words: 291 - Pages: 2.... physical proof that human beings may have evolved from ape-like creatures. Even with this, there are still disputes in the paleoanthropological field of whether or not this is true. Still, many choose to believe their religious creation stories where a God created humans. Whether it is Johanson's idea on human evolution or Leakey's or even the Roman Catholic's creation story, all are an individual own interpretation and neither wrong nor right.
A paleanthropologist by the name of Donald Johanson is one of the many who have a very different view on the origin of humans. In 1974, he discovered forty percent of an individual dating back to 3 .....

Darwin's Theory And Modern Genetics
Words: 324 - Pages: 2.... certain parts of a population is natural selection.
Studies were being done during Darwin’s findings that indicated there was a “gene” associated with certain characteristics. Mendel’s pea plants proved there was a way of artificially creating trends in color of flowers. This discovery led to modern genetics. We now know chromosomes carry valuable information that determines characteristics in living species.
When you put these two discoveries together you really understand how animals have evolved to their currant state. When animals are born the have traits that help them live or inhibit their ability to live. If the .....

DNA
Words: 1416 - Pages: 6.... in plants and animals.
All DNA molecules contain a set of linked units called nucleotides. Each
nucleotide is composed of three things. The first is a sugar called deoxyribose.
Attached to one end of the sugar is a phosphate group, and at the other is one
of several nitrogenous bases. DNA contains four nitrogenous bases. The first two,
adenine and guanine, are double-ringed purine compounds. The others, cytosine
and thymine, are single-ringed pyrimidine compounds. (Miller, 141) Four types of
DNA nucleotides can be formed, depending on which nitrogenous base is involved.
The phosphate group of each nucleotide bonds with a carbon from the d .....

Cobalt
Words: 332 - Pages: 2.... It is a very
expensive metal that is used in the manufacture of very many expensive alloys.
Cobalt-iron alloys have very unique and special magnetic properties. For
example, Hyperco is used as the nucleus in strong electromagnets. Alloys
containing titanium, aluminum, cobalt and nickel can be made to become
permanently magnetic. One alloy, called Stellite, is an alloy of cobalt,
chromium, tungsten, and molybdenum. This alloy is extremely hard and keeps its
hardness at extreme temperatures. It has many uses: cutting tools are made of
it along with gas turbines. Zaire is the world¹s largest producer of cobalt
with 65% of the world .....

Genetic Engineering -
Words: 980 - Pages: 4.... is to sequence all human DNA by 2003, the Human Genome Projects current target date (Lemonick 46). But we should use genetic engineering in a proper way. Our goal should be to find areas where it is needed rather than try to misuse it for personal gain. Genetic engineering can provide medical benefits to humans, but limits have to be set.
Our body contains one hundred trillion cells, inside most cells is a nucleus that contains a complete set of the body’s blueprints. Those blueprints are twisted into forty-six packets called chromosomes. Unravel a chromosome, and you get the long, thread-like molecule called DNA. Within .....

Solar Cells
Words: 1163 - Pages: 5.... as there are protons, so, on the whole, it is electrically neutral. The electrons have discrete kinetic energy levels, which increase with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into bands.
In electrical conductors, these bands are continuous but in insulators and semiconductors there is an "energy gap", in which no electron orbits can exist, between the inner valence band and outer conduction band [Book 1]. Valence electrons help to bind together the atoms in a solid by orbiting 2 adjacent nucleii, while conduction electrons, being less closely bound to the nucleii, are free to mo .....
