.... the DNA molecule (DNA is considered a single molecule) is the base. There are four different bases found in deoxyribonucleic acid. These bases connect together into a long chain of bases to form the DNA molecule (much like pearls connect together to form a pearl necklace). The names of these four bases are adenine, cytosine, guanine, and thymine. Conventionally the bases are abbreviated as A, C, G, and T (respectively) for simplicity reasons. At the smallest level, DNA is organized into a double helix. The DNA helix is then repeatedly coiled to allow more of it to fit into a compact space. This helix replicates and passes on its information to the body's cells .....

.... gram positive, and gram negative if the bacteria is de-coloured. This could be noted by the final colour of the bacteria: a violet colour where Gram positive and a pink colour of the Safranin added pending the de-colouring process. Materials: 1. Bacteria Sample 2. Microscope Slide 3. Gram Staining Kit and Wash Bottles a. Crystal Violet Solution b. Iodine Solution c. 95% Ethyl Alcohol d. Safranin e. Distilled Water 4. Bibulous Blotting Paper 5. Microscope 6. Oil Procedure: A. Preparation : 1. Bacteria is cultivated on agar jelly in an incubator at 25°C for 24 hours. 2. Obtain a microscope slide and with a toothpick, smear a thin coat of the bac .....

.... by implanting the fertilized egg into her uterus. In a third method the ovum is fertilized within one woman's uterus and then transferred to the body of another woman. Eggs can now also be removed from a woman's ovaries and placed in her fallopian tubes along with spermatozoa, thus allowing for normal fertilization. Many times anonomus donors are used. Donors can be matched by factors such as race, color of eyes, hair and other physical characteristics, and are screened for conditions such as AIDS, gonorrhea and other STDS. Even though freezing sperm doesn't seem to affect a pregnancy, it reduces the sperm's movement and influences the success rate of . A .....

.... chemicals, they will not stop them completely. Nicotine is an addictive drug and also one of the most dangerous ingredients in cigarette tobacco. Cigarette smokers are addicted to the nicotine in cigarettes just like a junkie is addicted to heroin or cocaine. When a person smokes a cigarette the body reacts immediately to the chemical nicotine. Nicotine begins to effect a smoker’s blood pressure, the flow of blood from their heart, the heart beat and breathing rate. Cigarette smoke also contains carbon monoxide, the same poisonous gases released from a car exhaust pipe. Carbon monoxide is a colorless and odorless, highly toxic gas that .....

.... of injury. The second is no horseplay. Horseplay can cause injury to yourself others and can cause damage to the laboraty. The third rule is that you should only interact with your partner and the teacher. This will prevent distraction from your set experiment. The fourth rule is that you should not leave your experiment unattended whether you think it is dangerous or not. This rule is completely self explanatory for safety purposes. The fifth rule is to be extremely careful with equipment. Not only for money purposes but also for your own personal safety. The sixth rule is to not touch anything that the teacher or the lab specifically instructs .....

.... for the most cures. Many doctors must operate on their patients, but this treatment has several downsides. Just because a doctor has taken out the main tumor doesn't mean that the cancer cells are completely gone. They're too small to see, so doctors can't tell if they have taken it all out or not. So, just to be sure, doctors usually take out a lot of the healthy tissue surrounding the area. This could damage the person's system and their appearance. Also, cancer sometimes forms around structures that can't be taken out, like an organ. In these cases, surgery alone is basically useless. Radiation therapy is another option, and many doctors prefer this in .....

.... which were later incorporated in the electrostatic force law. One idea was that there are two types of electricity, which were later named positive and negative by Benjamin Franklin. Another idea was that electric samples of the same kind repel each other, and those of different kinds attract each other. This later was named the law of electrical charges, and is essential to the understanding of electricity. A third idea was that if the distance between electric charges is increased, the force of attraction or repulsion decreases. All matter is made up of very tiny particles called atoms. Atoms are made up of even smaller substances called su .....

.... of that organism and why I chose to conduct tests on it. I then, with the information at my disposal, conjured a hypothesis which I would test. Using the materials at hand I, to the best of my ability tested my hypothesis. In conducting the tests I created graphs and tables of my work. At the conclusion of my experiment I came up with an answer that was almost unpredictable with the information that I was using. Although this was a crude experiment, I believe that I did gain a lot from it. Introduction The drug that I chose, Ibuprofen, is an anti-inflammatory analgesic. It is propionic acid that is white and powdery, and soluble in water, and o .....
