.... gives bone its tenacity, elasticity and its resilience. It also has an inorganic component located in the cement between the fibers consisting of calcium phosphate [85%]; Calcium carbonate [10%] ; others [5%] which give it the hardness and rigidity. Other than providing the rigid infrastructure, it protects vital organs like the brain], serves as a complex lever system, acts as a storage area for calcium which is vital for human metabolism, houses the bone marrow within its mid cavity and to top it all it is capable of changing its architecture and mass in response to outside and inner stress. It is this dynamic remodeling of bone which is of primary interest in microgravity. ....

.... actually had morals, then abortion might not occur. No matter what anyone argues, abortion is murder, plain and simple. How could one deny that when a doctor grabs his forceps and crushes a child's skull and sucks out what was once a brain, how could they say that is not murder, how could someone get away with doing this. Then again people ask that same question about OJ. There are many abortion-slaughter techniques that are used today. Examples are the Dilatation and Curettage (D&C) where a loop shaped steel knife is inserted and the child is cut into pieces, also there is the Dilatation and Evacuation (D&E) where the doctor uses forceps with sharp metal jaws and tears ....

.... their children about sex and birth control. Also, parents believe that there should be a heavier influence on teaching the students about birth control products and sex education, instead of distributing free condoms. Passing out free condoms at high schools may have a negative effect on the way young adults view sex. In high school, young adult's emotions and feelings are still very immature; therefore, passing out condoms may be promoting teenagers to have sex. Parents think giving free condoms to children sends mixed messages on what to think about sex education or how to have sex. Promoting safe sex and distributing free condoms in high schools are great ways to ....

.... producing cells in the lower brain trigger bursts of electrical activity that radiate up to the cortex, which makes sense of these signals by reaching into it's memory file for images, information and experiences and weaving them into a story (Kopecky,76). Psychiatrist and philosopher Gordon Globus of the University of California at Irvine, says to determine what kinds of stories they are and to figure out what they can tell us. He says "you need to look beneath the surface of a dream to find the coherence" (78). Since 1853, when REM, or the dream state, was first recognized about thirty studies have explored gender differences in dreaming. These research studies on the g ....

.... will be leaving because there are no guidelines on when this stage will come or pass. The time of retirement, and when all the children have left, is called the empty nest. For most parents, this is the threshold of their lives and usually includes a large lifestyle change. They have the crisis of losing their role as a parent and needing to find a new sense of identity without this role. Feelings that come with this part of the crisis include depression, self-doubt, heartache and low spirits. They must also handle any kind of regret or feeling of failure about their time and place as a parent. As a mid-life parent, some people (mostly women) can feel caught in the "san ....

.... They were to be used as tests subjects. 25 of the workers were exposed to the virus, 7 died. The same virus had confirmed cases in Uganda at approximately the same time. Sporadic instances of the Marburg strain have been reported in several other African countries since then. The first major outbreak of the ebola virus was in 1976, in Zaire and in Sudan. "Over 500 cases were reported, with mortality rates of 88% in Zaire and 53% in Sudan"1 The cause of these outbreaks still remain unknown. No association with monkeys could be attributed to either of the outbreaks. The only other case besides in Marburg that Ebola seemed to be associated with monkeys was a filovirus (famil ....

.... in the meat is used to build muscles, the lettuce, pickles, onions are also absorbed. In the stomach, which is a muscle, the food is churned about while digestive juices pour int from glands in the stomach wall. Eventually, the the churning action moves food out of the stomach and into the small intestine. The lever contributes to this digestive process by secreting into the small intestine, a liquid called bile. The pancreas secretes pancreatic juice which further aids in dissolving food. The small intestine undergoes continual muscular contractions called peristalses. This action pushes food into the large intestine. This surface of the small intestine has ....

.... done by NAS, the Surgeon General, Department of Agriculture and Health and Human Services, and the National Institute of Health. Based mainly on the study by NAS done in 1982, the American Institute for Cancer Research (AICR) devised a guideline with four parts to help lower people's risk of developing cancer. The guidelines have been updated since then to reflect recent research on the link. The AICR guidelines are: 1. Reduce the intake of total dietary fat to a level of no more than 30% of total calories and, in particular, reduce the intake of saturated fat to less than 10% of total calories. 2. Increase the consumption of fruits, vegetables and whole grains. 3. Con ....
