Diabetes 3
Number of words: 769 | Number of pages: 3.... pregnancy make controlling blood sugar more difficult for a woman who has diabetes. Changes in the levels and types of hormones produced during pregnancy can cause insulin resistance, increasing the body’s requirements for insulin. Poorly controlled diabetes may endanger the fetus as well as the woman. With proper adjustments in insulin the risks lessen. Diabetes increases a pregnant woman’s risk of infection, early labor, and high blood pressure caused by pregnancy. The baby of a diabetic woman may be unusually large at birth. The risk of birth defects is two times higher in babies of women who have diabetes. Most women .....

History Of The Cell Theory
Number of words: 326 | Number of pages: 2.... are composed of cells.
2. Cells are the basic units of structure and function in organisms
3. All cells come from preexisting cells.
The impact on science was very great due to the discovery of cells and
the cell theory. Many or all things were effected by the discovery of cells,
everything was looked upon in a different way. Some people still did not
believe that all living organisms were made of tiny microscopic chambers called
cells. Many people thought that people that believed in cells were insane, some
people even wanted to put Antoni van Leeuwenhoek in an insane asylum because he
believed in cells. As you can .....

Cloning 2
Number of words: 946 | Number of pages: 4.... whose genetic constitution is a replica of
another existing individual. Such a feat can be achieved by substituting the nucleus, which
contains the genes, from one of the cells making up that individual's body, for the nucleus
of a fertilised egg.
Since our genes dictate to a large extent what we look like, how we behave and what we
can and cannot do, having identical genes, as identical twins do, ensures something more
than mere similarity. Novelists and film makers have not been slow to exploit the imagery
afforded by cloning. Limitless numbers of identical beings manufactured from existing or
previous generati .....

Oxygen
Number of words: 752 | Number of pages: 3.... chosen the element "Oxygen" because without Oxygen, human beings
would not be able to live. Oxygen is probably the single most important element
in the world as we know it. With out Oxygen we would not breath, have water, eat
plants.
Oxygen's Electron configuration is 1S2 + 2S2 + 2P4, it's electron dot
symbol is: .
Gaseous oxygen can be condensed to a pale blue liquid that is
strongly magnetic. Pale blue solid oxygen is produced by compressing the
liquid. The atomic weight of oxygen is 15.9994.Oxygen composes 21
percent by volume or 23.15 percent by weight of the atmosphere; 85.8
percent by weigh .....

Supernovas
Number of words: 1068 | Number of pages: 4.... nuclear energy. If the star is particularly massive, then its core will collapse and in so doing will release a huge amount of energy. This will cause a blast waver that ejects the stars envelope into interstellar space. The result of the collapse may be, in some cases, a rapidly rotating neutron start that can be observed many years later as a radio pulsar. As a result of gravitational forces acting against the nuclear structure of the core of a fuel depleted star, tremendous shock wavers are generated which cause the outside layers of the star to be blown away from the core. This can happen in one of two ways depending on the ty .....

Silicon
Number of words: 1438 | Number of pages: 6.... of other devices.
Silicon belongs to the group IV in the periodic table. It is a grey brittle
material with a diamond cubic structure. Silicon is conventionally doped with
Phosphorus, Arsenic and Antimony and Boron, Aluminum, and Gallium acceptors.
The energy gap of silicon is 1.1 eV. This value permits the operation of
silicon semiconductors devices at higher temperatures than germanium.
Now I will give you some brief history of the evolution of electronics
which will help you understand more about semiconductors and the silicon chip.
In the early 1900's before integrated circuits and silicon chips were invented,
compute .....

To ensure that the person using the card is actually the card holder. The buyer might have exceeded the limit or can be using a stolen card. Likewise, the buyer has no assurance that the vendor on the other end is who he/she claim to be. Richard E. Smith in Internet cryptography says that data travels from one computer to another leaving the safety of its protected surroundings.

James Watson's The Double Helix: A Review
Number of words: 1915 | Number of pages: 7.... Franklin (also known as Rosy).
Initially, Wilkins thought that Rosy was supposed to be his assistant in
researching the structure of DNA because of her expertise in crystallography;
however, Rosy did not want to be thought of as anybody's assistant and let her
feelings be known to others. Throughout the book there is a drama between
Wilkins and Rosy, a drama for the struggle of power between the two.
Watson's "adventure" begins when he receives a grant to leave the United
States and go to Copenhagen to do his postdoctoral work with a biochemist named
Herman Kalckar. Watson found that studying biochemistry was not as exci .....

Biome Broadcast
Number of words: 969 | Number of pages: 4.... third trail was four
miles long. Since it was such a beautiful day we all decided to take the third
trail that was four miles long.
We started hiking around 11:00 AM. While we were hiking we heard wings
flapping, we all turned and saw a robin fly towards the ground, pick up a worm,
and feed it to her babies. Everyone thought that it was cute. After, we
watched the robin for a while we continued hiking until 12:30 PM.
Everyone was hungry so we decided to find a spot to eat our lunches. We
found a perfect spot, it had a great view, a patch of beautiful dandelions, and
a big beautiful maple tree to sit under.
A picture of the .....
