...ACID RAIN Acid Rain Acid rain is defined by Kumar as a term used to de "Any precipitation which has a value less than 5.6,the PH of uncontaminated water".1 In most cases, Kumar notes that acid rain falls under a PH of between 5.6 and 3.5.2 It is important to note that evidence of acidic precipitation appears after a few days and long distances from the origin. Acid rain can be prevented through a number of ways in future. According to Casper, acid rain can be prevented in future is by switching to sources of energy that emit low levels of carbon.3 Combustion of fossil...

Aristolochic acid is highly carcinogenic (cancer-causing) and nephrotoxic (harms the nephrons in the kidneys) [1]. Normally, this type of acid is found in several natural, botanical products sold commonly as 'traditional medicines' and in diet-supplements/weight loss preparations [11]. Urinary tract damage and other cancers have been linked to the intake of aristolochic acid as well as kidney damage and kidney failure which requires dialysis or worse, kidney transplantation [2].

The pH values at the observed equivalence points were nearly 1.5 times lower than the calculated values which were made based on the assumption that the molarity of the titrant NaOH was 0.2 while it actually was 0.232.

...acid as a potential treatment that could arrest the growth of tumor cells or prevent metastasis to neighboring tissues. Conjugated linoleic acid or CLA is a molecularly re-arranged version of linoleic acid derived from dairy and meat products from ruminant animals, such as beef, lamb, and veal. CLA have been found to reduce the body weight, fat production, and incidences... Introduction Breast cancer is the third leading cause of death among women in the world.

...Acid-Fast Bacteria What is the purpose of general growth media, selective media, and differential media? Give examples of each. Growth media is a gel or rather a liquid that is used to support the growth of the microorganism or small plants. Examples include; nutrient broths. Selective medium is a technique used to grow particular microorganism for instance if an organism is resistant to an individual antibody i.e. ampicillin then that antibiotic is added to the growth medium in order to prevent cells that do not have resistance from growing. Example, Hektoen enteric agar. Differential media is a method that is utilized to distinguish one microorganism from the next in situations...  Gram-Positive and...

...Acid Rain and Alkalinity of the Lakes in Canada Surface and soil waters such as lakes and streams receive acid from a variety of natural sources. Natural sources of acids is obtained by decomposition of animals and plants, forest fires, volcanoes, which produce sulfur oxide/sulfuric acid. Carbonic acid is formed by carbon dioxide in the air, and the lightning bolts changes nitrogen molecules in air to nitrogen oxides and nitric acid. In the same way, surrounding vegetations also determines the acidity or alkalinity of the lake, such as types of trees, soil, and decaying...
