... samples of maternal blood instead of amniotic fluid. The problem with amniocentesis is it uses a hollow needle to take fluid from the mother's uterus. The needle could damage the developing fetus if not inserted properly. Another advantage of FISH is that the parents get a much quicker test result than amniocentesis. After the sample is taken, amniocentesis can take up to three weeks before a test can be administered. With FISH, a same day result is given, which is much more convenient to the parents. Additionally, FISH is a simpler process. It uses specially prepared molecules which bind to specific regions of DNA. To find a particular gene, the examiner just ...

... tops the list. Carnegie Mellon University reports, "recruitment of its software engineering students is up this year by over 20%." All engineering jobs are paying well; proving that highly skilled labor is what employers want! "There is clear evidence that the supply of workers in the [unskilled labor] categories already exceeds the demand for their services," says L. Mishel, Research Director of Welfare Reform Network. In view of these facts, I wonder if these trends are good or bad for society. "The danger of the information age is that while in the short run it may be cheaper to replace workers with technology, in the long run it is potentially self-destructive ...

... giant panda is a large mammal weighing between 165-353 pounds. Its body length is between 4-5 feet including a tail that is five inches long. Their vision is poor but their sense of smell is excellent. They have a woolly black and white coat, which is slightly oily to prevent water penetration. Giant pandas are very cool looking animals. This is why we have to do everything we can to save them. The giant panda’s breeding season takes place from March to May. Then the baby pandas are born three to six months later weighing only eighty-five to one hundred forty grams. Two cubs may be born from one mother at the same time, but only one will survive. Th ...

... and create perfect clones of themselves at alarming rates. The efficiency that these diseases carry is also alarming. They are able to lie dormant for years before attacking their next victim. It is for this reason that the number of cases increases on a yearly basis. This is why individuals should take further precautions in preventing these diseases as well as preventing the spread of them on a global scale. Many people in today's society must take a more serious look at the implications that an infectious disease can have on one's life. What are STDS? Sexually transmitted diseases (STDS), also known as venereal diseases, is a broad term that refers to m ...

... Reproduction takes place as follows: The male octopus uses his tentacle to take a mass of spermatophore from within his mantle cavity, he then inserts it into the oviduct, in the mantle cavity of the female. This process occurs at depths from 20-100m and, lasts hours. With female octopuses receiving spermatophore up to 1m long. Female octopus seem to prefer larger males as mates and male octopus may mate with more than one female in their life span, however the male octopus only lives a few months after breeding, and the female will die shortly after the eggs hatch. Incubation can take from 150 days to seven or more months. The female may produce any where f ...

... equaled Athena's skill in a contest, and in response to Athena's anger she hanged herself.

The brown recluse spider (Loxosceles reclusa) is a poisonous spider in in the United States. Its mostly found from Kansas and Missouri, south to Texas, and west to California. Found in sheltered places indoors and outdoors it is about 10 mm (.4 in.) long and has an orange-yellow body with a dark violin-shaped design on its back. Its bite isn't usually fatal to humans, the venom destroys the skin and it ma ...

... 2 Mining When uranium is extracted, pitchblende is broken up and mixed with sulfuric and nitric acids. It then dissolves into uranyl sulfate. With the addition of sodium hydroxide, uranium is precipitated as sodium diuranate which is known as the yellow oxide of uranium. To get uranium from carnotite, the ore must be finely ground and treated with a hot solution of caustic and potash to dissolve out the uranium, radium, and vanadium. And after the sandy matrix is washed away, the solution is treated with sulfuric acid and barium chloride. A caustic alkali solution is then added to the remaining clear liquid precipitates the uranium and radium into co ...

... of several hundred species of plants, most of which are evergreen shrubs belonging to many plant families such as the rose, oak, heath, buckthorn, and sumac. Common shrubs of the are chamise, scrub oak, mountain lilac, manzanita, and sumac. The plants have evolved to withstand long, dry summers and strong autumn Santa Ana winds that create frequent fires. The leaves of the plants are mostly thickor needle like so it can reduce water loss through evaporation. The chamise, for example, has small, needle-like leaves that store up and save the moisture in the plant. The is the home of many species of reptiles, birds, and mammals. There are animals such as the ...

... profit. More specifically, premiums less costs provide the all important profit margin, the life blood of the insurance industry. By not providing coverage for the billion dollar industry of alternative treatments, insurance companies are keeping the cost of the premiums down but at the same time not allowing their customers to use complementary treatments such as chiropractic to prevent or cure illness. The more rigid and restrictive the policy provisos, the more assurance for the companies that they will maximize their bottom lines. Therefore, patients of alternative therapies as well as doctors must show that such unconventional treatment provides r ...

... in your car, and tell the computer where to go. Therest will be done automatically. This will be a safer, faster, and morecomfortable way to travel. Another new area, called "virtual reality" is currently being tested. This is away to simulate reality on a monitor. In order to feel this so-called realityyou have to wear special electronic glasses and an electronic suit. Fastened tothe suit are sensors, which send information to the main computer. Thiscomputer works with the data and displays them on the electronic spectacles. This is a technique which use three-dimentional views, therefore the scenery seems incredibly realistic.
