.... a strong odor to it. These results led me to my conclusion that substance C is ammonia. Test-tube D: Test-tube D contained lemonade. The substance reacted to blue litmus paper, and red litmus underwent no changes. It had no effect on Phenolphthalein, and its pH value was 3, a strong acid. Knowing that lemons are very acidic, and that the substance was yellow and sweet smelling, I concluded that substance D was lemonade. Test-tube E: I could not come to a conclusion on what substance E was. It reacted weakly to blue litmus paper, and it did not change red litmus. It had no effect on Pheno .....

.... They have small, round bumps on the front of the head edging the jaws. Humpbacks have huge, mottled white flippers with rough edges that are up to one-third of its body length; these are the largest flippers of any whale. The humpback's genus, Megaptera, means "huge-wings," referring to its flippers. The flippers may have barnacles growing on them. The deeply-notched flukes are up to 12 feet (3.7 m) wide. Humpbacks have a small dorsal fin toward the flukes. DIET AND BALEEN Humpback whales (like all baleen whales) are seasonal feeders and carnivores that filter feed tiny cru .....

.... have a cure for cancer and can save hundreds of thousands of human lives. Of course if you value the life of a mouse over a human then you would see differently. Some fear that this science is too powerful, granted we shouldn't let just anyone be able to modify bacteria, or the human genome, but we shouldn't let our fears blind us to the possible benefits of wide-scale genetic engineering. Medical uses for this technology are virtually endless. With genetics we can filter out any genetic defect, no more down-syndrome, mal-deformed limbs, hereditary cancer, or any other hereditary diseases. .....

.... 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 adenosine blocking remains the dominant factor. The other two laboratory eff .....

.... that animal experiments can not only mislead researchers but even contribute to illnesses or deaths by failing to predict any toxic effect on drugs. The majority of animals in laboratories are used for genetic manipulation, surgical intervention or injection of foreign substances. Researchers produce solutions from these animal "models" and are adapting them to human conditions. Unfortunately, these animal "models" can't always be connected with the human body thus creating problems. Many times, researchers induce strokes on animals in order to test certain methods for curing. The down .....

.... Alfred R. Wallace, came out with a theory that was almost identical to Darwin’s theory. Darwin’s theory was much more developed and better known. For example Darwin pointed out that farmers would take certain qualities from two different plants and mix them together and it would produce the desired plant. He believed this happened in nature also and he called it “the survival of the fittest” or “natural selection.” There are a lot of different creation stories and they are the same in that since but they are all different. The creatio .....

.... is in tablet form. Other ways to get barbiturates include ampoules, syrup, or capsules. For injection, which is rarely used because of its risk factor, capsules are opened and the powder is added to water. However, this can cause damage to the veins. Barbiturates come in different types such as Soneryl, Nembutal, Amytal, and Tuinal. Small doses relax the user, depressing the nervous system while the effects last up to 8 hours depending on the dosage. Large doses can cause loss of co-ordination, slurred speech, and give the appearance of being drunk. The lethal dose is especi .....

.... National Cancer society as aggressive or fast multiplying or indolent, slow multiplying. ( Information Network) The lymphatic system protects the body from agents that could cause disease like bacteria or viruses. Within this system, that consists of organs such as the spleen and tonsils, there are organs that destroy foreign agents, those organs are called lymph nodes. The lymphatic system works as follows; the bone marrow produces blood cells including white blood cells. White blood cells are the cells that find and destroy disease-causing agents. Both B and T cells change a great dea .....

.... aluminum is not very strong and is highly reactivate with Oxygen, water, acids, and bases it is compounded with other metals and elements to from alloys for common uses. In Society Aluminum Alloys are used in many ways because of it's light weight and versatility. As more and more ways are discovered to strengthened Aluminum with other elements more uses have also been discovered Aluminum is used in aircrafts, Electrical Engineering, Windows, doors, buildings, packaging and many other things. When aluminum is compounded with other it gets stronger for multiple uses. It is usually is com .....
