.... For example a muscle cell wants potassium and wants to get rid of a sodium, the cell releases ATP to the pump proteins which results in the cell ejecting the sodium ion and at the same time another receptor cell accepts a potassium which is then released into the cell and the process is repeated until the cell is finished.
c.Facilitated Transport
In facilitated transport a molecule that cannot normally pass through into a cell use a carrier protein to gain access and exit. Basically this .....

.... of this, a CT scanner is said to be 100 times as affective and clever as an ordinary X-ray, and can therefore diagnose some diseases a lot earlier and quicker. It is recent technology that has made it possible to accurately scan objects into a computer in three dimensions, even though the machines and ideas were developed in the 1970s. In the 70s doctors started to use this new type of machine that could give detailed pictures of organs that the older type of x-ray, machine could not give.

Fourth to record music onto a compact disk you would have to buy the equipment. The equipment for that operation would cost around two thousand dollars just for the cheapest one. That does not include the compact disks you need to record on. Those compact disks cost around eighteen dollars for a basic one length recording disk. If you want to go and record infofmation on a CD:ROM it wo .....

Energy related indicators shoe the positive effects of technoscientific application. While the production of coal, oil, natural gas and nuclear power each expanded by 1 percent in 1995, wind electric generation expanded by 33 percent and sales of solar cells climbed 17 percent (Brown, 5658). The harnessing of wind and solar energy does not create the environmentally harmful byproducts associat .....

Climate Change (term Paper)
.... more significant, on an ecological level, is the rise in per capita energy and material consumption which, in the last 40 years, has soared faster than the human population. “An irresistible economy seems to be on a collision course with an immovable ecosphere.” Based on these facts alone, there is grave reason for concern.
Taken further, it is even more frightening to note that, while man has affected the environment throughout his stay on earth, the impact has been most intense in the relative .....

Cloning 6

Cloning can only bring good things to our culture and our lives. The scientific advancements that could be used in everyday life would benefit mankind even if we d .....

C. Adapting
Conclusion-Computers are changing the world as we know it, and they offer an exciting new way of working.
The news represented a complete turnaround for the corporate giant. Microsoft Chairperson, Bill Gates publicly announced his company's new connection to the Internet. The announcement rang through the nation. Gates has consistently ignored the Internet in favor of desktop computing. So, with Microsoft's ap .....

Canadian Black Bear
.... Its metabolism slows down by half, and its body temperature reduces by 3 to 7 degrees Centigrade (5 to 9 degrees Fahrenheit). Also its body doesn’t release any wastes like urea or solid fecal waste but instead it’s recycled into usable proteins. During the hibernation period adult males and adolescent bears lose between 15% and 30% of their weight while a female cub with newborn loses as much as 40% of her weight. Most black bears vacate their winter dens over a one to two month period starting in April o .....

Chrones Disease
.... layers of the intestinal wall. Crohn's disease can also affect the also affect the colon, the regional lymph nodes, and the mesentery (outside covering of the intestines). The disease can be aggravated by a bacterial infection. It begins with the development of patches of inflammation on the intestinal wall, which can spread from one part of the digestive tract to another. It sometimes only develops in one place and does not spread any further. The inflammation causes the thickening of the intestinal w .....

Creatine 2
.... to ADP (adenosinediphosphate). When all the ATP is broken down, creatine phosphate in the muscle donates a phosphate group to ADP, and further energy reactions can occur. Creatine Monohydrate is a precursor to creatine phosphate. By supplementing with CM, CP levels in muscle apparently are maximized, and more muscular work can occur, since there are greater energy reserves to use. Approximately 95% of the body's creatine supply is found in the skeletal muscles. The remaining 5% are scattered throug .....

Carbon Dioxide
.... this is that there are less trees and plants to take in the CO2 but there is just as many, if not more, humans and animals to breathe it out.
The amount of CO2 in a planet's atmosphere affects the temperature of the planet. As more and more CO2 builds up in the atmosphere, less heat can escape and the planet gets hotter. The CO2 traps radiation from the sun like a greenhouse. This is called global warming or the greenhouse effect. Global warming is becoming a serious problem and CO2 is the major .....

Cells
.... the cell’s nutrient absorption and waste expulsion processes. Since the cell membrane of an eukaryotic cell is its only source of nutrition, its surface area must be large enough to allow the cell’s organelles to receive the material it needs or it will die. The eukaryotic cell does this by maximizing the surface area to volume ratio. By using the surface area and volume equations for a sphere you can estimate the surface area of a small cell. By modeling the growth rate of the surface area and volume of .....

3. What is Satellite Communications?
This is the use of orbiting satellites to relay microwave transmissions from earth stations to the satellite an to re-transmit those signals back down to another earth station by means of microwave transmission.
Cellular Radio
At present there are two types of cell .....

Chlamydia

Chlamydia s simple to cure. Physicians prescribe a one day course of an antibiotic, azithromycin, and it’s gone. Penicillin, which cures many other bacterial STI’s, doesn’t work on chlamydia.
The best way to prevent becoming infected with the bacteria is to practice safe sex. Condoms and diaphragms are affective.
