... into shelf like structures called cristae. The cristae does not even allow the passage of small ions and so it maintains a closed space within the cell. The many infoldings of the cristae are responsible for providing the mitochondrion with a large surface area which enhances the productivity of respiration. The inner membrane and outer membrane effectively divide the mitochondria into two internal compartments. The space located between the outer and inner mitochondrial membrane is called the intermembrane space. The space enclosed by the inner membrane is called the mitochondrial matrix. It is here that many of the metabolic steps of cellular respiration occ ...
... increase the risk of injuries (Edlin p.130 ). If you exercise regularly, your overall risk of a heart attack is about 50 percent less than if you are inactive and out of shape. With routine exercise you can reach a level of physical fitness comparable to an active person ten to twenty years younger. Regular exercise may also lower your cholesterol and blood pressure, and reduce the risk of diabetes. Exercise increases the size of coronary arteries and reduce clogging due to atherosclerosis. Exercise also increases the efficiency of your blood's oxygen-carrying capacity and your muscles' uptake of oxygen. Exercise has been linked to increased levels of hi ...
... tea tree, some tea leaves fell into Sheng's pot of boiling water. After drinking some tea, he discovered its miraculous powers and immediately placed tea on his list of medicinal herbs. John Blofeld, in Chinese Art of Tea, writes that ¡§it can be confidently stated that tea was known in the three kingdoms epoch (AD 222-277).¡¨ More importantly, however, ¡§tea [was] originally drunk for its medicinal properties.¡¨ (Blofeld 4) Evans links the early popularity of tea to Taoist religious practices during the Qin Dynasty (201 ¡V 207 B.C.). ¡§Taoists in particular became obsessed by long life and an Elixir of Life became a Taoist ideal. For Taoists the Elixir ...
... since it's a way to distribute movies with extended features such as user-selectable camera angles and multiple language support. Also, like CD's, there are writeable and rewriteable variations coming. DVD is just starting to make a significant impact on the market. Estimates vary from about 600,000 to 1,000,000 console players ("living room" boxes used strictly to play movies) sold in the United States through the end of 1998. So far, the number of DVD drives in PCs is far smaller. DVD technology can handle one or two layers of data per disc side. That makes for four sub varieties of DVD-ROM, the read-only version of this technology: DVD5 (single side, ...
... fact, and thus claimed that Dolly and her “mother” were genetically identical, which sparked a fury of outcry all around the world. The technique of transferring a nucleus from a somatic cell into an egg cell of which the nucleus had been removed, called nuclear transplantation, is an extension of research that had been ongoing for over 40 years. Up until now, scientists thought that adult cells could not be “reprogrammed” to behave like a fertilized egg and create an embryo, but the evidence obtained by Dolly’s success prove otherwise. The issues of cloning have been around for a long time, starting with the publication of Joshua Lederberg’s 1966 artic ...
... funding for the project is nearly 60% of the annual need. This has created some funding problems for the project. There also have been technological advances and discoveries that have helped to speed up the project. This automation may help to reduce the cost and help the project to meet its objectives ahead of schedule. The project was estimated to have detailed maps of all of the chromosomes and know the location of most of the human Genes by 1996. Researchers have successfully located the gene and DNA sequence for Huntington’s Disease on Chromosome 4 and have created a genetic test to determine if a person carries this gene. "The child of a person with ...
... There are two very shy people in the room that sometimes leave the room. When they are in the room they stand by the walls and always wink for some reason, so all we can see of them is one of their eyes. (Mercury & Venus) Then there are three very weird people in the room that are always in the middle of the room doing the Waltz. They do this some how by themselves and they to are always winking. They are sometimes on the first floor and sometimes on the second floor. (Mars, Jupiter, and Saturn) There is also one guy dressed in a white polyester leisure suit, gold chains, and rings dancing to "Stayin' Alive." (comet) It seems as though everyone in the univ ...

... between living organisms and effects of their interactions are ecologists' concerns. . . . .The balance of nature, wherever it occurs, is what you will investigate and analyze"(17). Since a career as an ecologist is usually long term, there are certain characteristics a person should have in order to maintain a successful career. One of these characteristics that is the most important is patience. Patience is important because as an ecologist a person will have to at some point in their career talk to another person who knows nothing of or about ecology. Another reason why patience is important is because through the first years of being an ecologist finding and ...
... that, they spent three billion over the next several years on the clean up. During the cleanup, Exxon employed the assistance of 12,000 people and 1,385 ships and planes. They recovered a little over 2.6 million gallons of oil from Prince William Sound over the cleanup period. The estimated number of dead birds was 33,126 along with 138 eagles and 980 otters. Usually, when we are thinking of oil pollution what comes to mind is maybe a disastrous oil tanker spill somewhere in an ocean that ends up killing thousand upon thousands of wildlife living in that region. One example of this is the Exxon Valdez which spilled oil from its tanker into Alaskan waters and dumpe ...
