... Herrick was the first person to publish a medical report on . As the report accumulated, a patter emerged. In 1926, Dr. Thomas P. Cooley and Dr. P. Lee described two forms of sickle cell disease: and sickle cell trait. During 1945, Dr. Linus Pauling discovered that an abnormal form of hemoglobin was the reason for the sickness in sickle cell patients. These two took a train together and started talking about . Castle told Pauling about how the cells in sickle cell patients sickled when their oxygen level is low. Paling was amazed by this conversation and did further research on the disease. After that Pauling was able to tell which patient had sickle ce ...
... shortly by the infamous imported red fire ants. Black ants (Solenopsis Richteri Forel) were the first to arrive and spread slowly but steadily despite government intervention to stop them from spreading(3. Lockley 33). These black ants would spread much further then the second wave of imported ants recognized as Solenopsis Invicta Buren or red fire ants(4. Lockley 33). This second wave of ants arrived in about 1945 and spread much more rapidly and dominated the previous more passive black ant(5. Lockley 34). Homer Collins, a fire ant expert, stated that "The new invader, known as the red imported fire ant, proved more adaptive and rapidly displaced the ...
... relationships. A consanguineous relationship means that the parents are genetically related (e.g. first cousins). Clinical traits are as follows: Hyperpigmented skin or as otherwise known, Acanthosis nigricans. This symptom is not exclusive to , as it is caused by high insulin levels. This pigmentation normally occurs in areas of the body where flexing and bending occurs, such as the back of the neck. Reddening of the skin or erythema. This is caused by localized irritation. Most often the areas of the body most affected are those such as the gluteal cleft, groin area, and other places that friction might occur. It is not limited to thes ...
... functional groups than adenosine as, for instance, seen in cyclic AMP. This means that caffeine will fit adenosine receptors as well as adenosine itself will. Thus, cyclic AMP remains active, rather than being broken down. Second among the effects of caffeine is phosphodiesterase inhibition. The phosphodiesterase class of enzymes includes a number of enzymes responsible for breaking down cyclic AMP, thus depriving the body of an energy supply. Caffeine fools phosphodiesterase into attacking it instead, which inhibits the breakdown of cyclic AMP. However, the concentration of caffeine required for this effect to become significant is sufficiently high that the ad ...
... a black hole. All are formed from the gravitational collapse of a star, usually having a great, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as Carbon, Oxygen, and Helium are consumed. This chain reaction fuels the star for millions or billions of years depending upo ...

Am astonishing fifty percent of all major automobile accidents, and murders are associated with . On and on the statistics point to the enormous dangers of , yet it is a legalized drug. As bleak as this problems seems to be on society as a whole, it is also rueful for the poor soul who is dependent. The life span of the ic is about ten years shorter than the non-drinker. The lifetime prevalence for ism in the United States is as high as fourteen percent. Taking these statements into consider ...
... The whole canal is lined with a mucous membrane. Digestion begins in the mouth. Here the food is cut and chopped by the teeth. The tongue helps mix the food particles with a digestive juice called saliva, which is secreted in the mouth. Saliva moistens the food so it can be swallowed easily. It also changes some starches into simple sugars. It is important to chew food thoroughly to mix it well with saliva. Thorough chewing cuts food into small pieces that are more easily attacked by digestive juices. Food should not be washed down with quantities of liquid to avoid chewing. From the mouth the food is swallowed into a transport tube, named the esophagu ...
... until the fumes cease. The remaining solution should be blue. Bring the beaker back to the lab station and add ~ 10 mL of distilled water. Stir the mixture, all the while adding ~ 8 mL of 6M of NaOH to the beaker. Check with litmus paper to ensure that it is slightly basic. Fill the beaker with up to 100 mL mark with distilled water. Heat the solution and allow it to boil for 5 minutes. Prepare a squirt bottle with hot water. Filter the solution and rinse the beaker with the hot water. Rinse the filter cake with hot distilled water. Transfer the filter paper into a clean beaker. Add ~ 10 mL of 3M sulfuric acid to the beaker in order to dissolve the filtr ...
... inland. The red kangaroo, which is found throughout Australia's interior grasslands, is the largest and most powerful species. A male may attain a head-body length of 1.5 m; have a tail 1 m long; stand 2 m tall; and weigh 90 kg. A gray kangaroo can clear more than 9 m (30 feet) at a bound and attain a speed of 48 kilometres per hour. The wallaroo, a smaller and stockier animal, may be dark gray to pinkish brown; it lives in rocky country throughout Australia except Victoria. These large kangaroos travel in groups (mobs) under the leadership of the largest male ("old man," or "boomer"), which dominates younger rivals by biting, kicking, and boxing. Each ...
... on the fins of dolphin fossils. In Twelfth Night, Shakespeare took readers back six hundred years before the birth of Christ and told of a boy named Arraign, who was cast into the sea by pirates. A dolphin came to his rescue and carried the boy home to Greece on his back. Plutocrat wrote Thathos, Odysseus' son, was saved from drowning as a young child through the aid of a dolphin. A roman scholar Plink the Elder, who lived in AD 23-69, wrote about a boy named Hermias. Hermias had many encounters with a friendly dolphin which he would except rides from. One day Hermias was thrown off the dolphins back by a sudden storm and drowned in the sea. The dolphin broug ...
