Viruses are simple life forms consisting of nucleic acid, encoding genetic information , and surface components of protein that enable them to enter cells. Viruses are unable to multiple outside of cells. Mono is found in the DNA in the body.

What causes mononucleosis is the Epstein-Barr virus (EBV), which is like herpes. The herpes virus also causes some cases of mono and other diseases ....

.... women will discover that they have breast cancer and another 44,300 women will die of it alone. Breast Cancer is a horrible disease and it devastates thousands of families each year. What makes it even more difficult to conceive is that a woman is at a very high risk just because she is a woman. The breasts which have been with her almost all her life, those which gave her children strength and growth, those which have been a symbol of beauty are now going to destroy her. These are facts which women who have the disease must face and the mental and psychological strain is unimaginable to those who are not affected. Article Research Article I As with mainly all ....

.... most intelligent beings on earth, we use our critical thinking capabilities to selectively choose what should be morally acceptable and what should be deemed unacceptable. To the best of our knowledge, we as humans are the only species in existence that wrestle with moral dilemmas. Absolute morality that will be agreed upon by the majority of a society is extremely difficult to determine since each individual has the ability to decide for themselves what is morally acceptable. It is because of this decision that our American culture intensely debates issues of morality such as abortion. The debate over abortion pits the rights to life of an unborn fetus against the right ....

.... states that a climatic change killed the dinosaurs, it has become the single most accepted theory for the dinosaur extinctions within the scientific community. It is called the dinosaur- greenhouse extinction theory. It says that a climate change via the greenhouse effect killed off the dinosaurs.

Some of the things that happened back then are also happening now, and if the dinosaur- greenhouse extinction theory is indeed true, then we are also in danger of dying from the greenhouse vertebrate killing mechanism, abrupt atmospheric changes, and the other effects caused by the increased greenho ....

.... not all the wishful thinking of those advocating repeal of abortion laws, can alter this. Those of us who would seek to protect the human who is still to small to cry aloud for it's own protection, have been accused of having a 19th Century approach to life in the last third of the 20th Century. But who in reality is using arguments of a bygone Century? It is an incontrovertible fact of biological science - Make no Mistake - that from the moment of conception, a new human life has been created. Only those who allow their emotional passion to overide their knowledge, can deny it: only those who are irrational or ignorant of science, doubt that when a human sperm fertilize ....

.... can simply make an appointment at an abortion clinic, show up for the procedure on time, and go home the same day of the operation. Abortion clinics are located across the globe, and the abortion itself is fairly inexpensive. An abortion with no complications can cost as little as $500.

On the most part, women who do have abortions done, do so without any major complications. As far as abortion techniques, there are several that doctors can cho ....
