AIDS is a disease that damages the immune system and interferes with a person’s ability to fight off disease. It is most commonly transmitted sexually‚ but can also be transmitted through infected blood exposure and through birth. Mayoclinic.com says “AIDS is a chronic‚ potentially life-threatening condition” AIDS is caused by the retrovirus HIV‚ HIV targets T-cells which are vital immune system cells and without them it is nearly impossible to fight a common cold let alone a life threatening disease

Administration by George D. Pozgar‚ the Acquired Immunodeficiency Syndrome (AIDS) is a fatal disease that destroys the body’s ability to fight bacteria and viruses. AIDS is caused by the human immunodeficiency virus (HIV). It is considered to be the deadliest epidemic in human history with the first case being reported in 1981. It has been estimated that more than 21 million people have died from AIDS. (Pozgar‚ 2012‚ p. 353 & 364) AIDS is a collection of specific‚ life-threatening‚ opportunistic infections

corresponding anthocyanidins using paper chromatography‚ and spectrophotometric analysis procedures. Based on experimental data the blueberries contained the most amount of anthocyanins at 1.92 x 10-6 g‚ followed by blackberries at 1.19 x 10-6 g‚ finally followed by raspberries at 5.84 x 10-7 g. The paper chromatography data also supports the idea that blueberries contained the most anthocyanidins‚ since it contained the most streaks on the chromatography paper. The main conclusion that can be

Plant Pigment Chromatography VII. Analysis (Questions) 1. What factors are involved in the separation of pigments? Factors that are involved in the separation of pigments can include pigment solubility‚ the attraction between the pigments and paper and the size of each pigment particle. Because of these factors the results were as they were. Beta-carotene traveled the furthest because it forms no hydrogen bonds to the chromatography paper and is slightly soluble in the solvent. Contrastingly

There are many uses for paper chromatography‚ especially concerning the fields of chemistry and biology. One use is to allow scientists to detect any sort of contaminants is rainwater. Another use is to identify clues at a crime scene such as blood‚ ink‚ or drugs. However‚ the more common use is to

AIDS (Acquired immune deficiency syndrome or acquired immunodeficiency syndrome) is a disease caused by a virus called HIV (Human Immunodeficiency Virus). The illness alters the immune system‚ making people much more vulnerable to infections and diseases. This susceptibility worsens as the disease progresses. HIV is found in the body fluids of an infected person (semen and vaginal fluids‚ blood and breast milk). The virus is passed from one person to another through blood-to-blood and sexual contact

When people hear candy chromatography‚ they don’t know what to think about it. They of course know that it had something to do with candy. But just don’t know what. Candy chromatography is fun and simple. Candy Chromatography is a fun project‚ plus it has to do with candy. Candy Chromatography is an experiment to find out the true colors of the dyes in candy. When you put a skittle or an M&M in your hand in hot weather‚ the candy tends to bleed the color. And sometimes it shows more than one color

What is chromatography- Chromatography is the separation of mixture by passing it in solution or suspension or as vapor. It’s a technique for separating mixtures into the components this needs to happen in order to do the 4 things analyze‚identify‚purify‚quantify. Many scientist use this to do the 4 steps. When analyzing its used to examine the mixture and to find out the relation with one another. In purifying you need to seperate or take away and put it by itself for further study. In identifying
