.... gene. Possession of a normal gene leads to the continuous, regular production of ADA in cells throughout the body. Without at least one properly functioning gene, children have no way of converting deoxyadenosine (a waste product) into inosine. This leads to the rapid build-up of deoxyadenosine in the system, which becomes phosphorlyzed into a toxic triphosphate, which kills T-cells. The result is an almost complete failure of the immune system and early death. Previous treatment options included bone marrow transplants, which worked well with matched donors. .....

.... with the beaker of distilled water. 3. Twist one end of the tubing. 4. Fold the twisted end over on itself. 5. Tie a tight knot. Leave the extra string. 6. Insert the transfer pipette (cut off top) about one third of the way into the tubing. 7. Tie a knot securely around the transfer pipette. Leave the extra string. 8. Add two transfer pipettes (two squirts) of the Gatorade solution to the tubing. 9. Add two transfer pipettes (two squirts) of the starch solution to the tubing. 10. If you spilled any solutions while transferring, carefully rinse the tubing. .....

.... be spread through coughing , mouth to mouth contact of mucous membranes during kissing. This is where the common nickname was derived "the kissing disease". In rare cases this disease may be transmitted through blood transfusions. The disease is usually transmitted to family members, friends and people that you may go to school with, rather then people that live in the same community. People often come in contact with the disease or EBV bacteria at least once in there life. Although symptoms are incredibly mild or they are not present at all. When the .....

.... experiment and what would happen in the experiment. In the preliminary experiment we didn’t use the safeguards so it wasn’t fair experiment. We did this because it gave us the idea what problems we might face when we did the main experiment and gave us the idea how to do it. The pondweed should create photosynthesis by the following equation: - 6CO2 + 6H2O 6C6H12O6+ 6O2 Photosynthesis occurs when plants take in Carbon Dioxide from the surrounding air in its leaves and water from the nearby soil in its roots. The leaves then take light en .....

.... diseas refers to those syndromes caused by blockage to the flow of blood in those arteries supplying the heart muscle itself, i.e., the coronary arteries. Like any other organ, the heart requires a steady flow of oxygen and nutrients to provide energy for rmovement, and to maintain the delicate balance of chemicals which allow for the careful electrical rhythm control of the heart beat. Unlike some other organs, the heart can survive only a matter of minutes without these nutrients, and the rest of the body can survive only minutes without the heart--thus the c .....

.... Another 5-10% have partial ADHD syndrome with one or more other problems, such as anxiety or depression.(CHADD) Gender and age affect the way the patients display their symptoms. Boys are more likely to have the disorder than girls.

ADHD may be observed in children before the age of four, but it’s signs are often mi .....

.... and how they made the spectroscope. Only then does he start to mention a element a french chemist belived to be new or maybe just a heavier from of nitrogen. Inert gases and there liquefaction points are then listed along when they when fisrt liquefied by a chemist. Welcome, Stranger! This talks about the rarest of stable enert gases, xenon. It also tells why that in 1962 so many expirements were done involving this gas. Fisrt it defines the word gas, and talks about different types in about four pages. Thens he talks about how it is combined with flo .....

.... most famous of experiments that illustrates classical conditioning is Pavlov's Dogs. In this experiment, Pavlov sat behind a one-way mirror and controlled the presentation of a bell. The bell was the conditioned stimulus. A conditioned stimulus was an originally neutral stimulus that could eventually produce a desired response when presented alone. Directly after the ringing of the bell, Pavlov gave the dog food. The food was the unconditioned stimulus. This means that the food caused an uncontrollable response whenever it was presented alone. That resp .....
