    Introduction Gibberellic acid(C19H22O6) was discovered back in the 1930s by Japanese plant pathologists. In the late 1800s, a disease called Bakanae, also known as the “foolish seedling” infected the rice crops in Japan, Taiwan and other Asian countries. The plants die after demonstrating extended growth patterns. Shotaro Hori, a Japanese plant pathologist, proved a type of fungus was the cause of the disease. The fungus was later named Gibberella fujikuroi. Years later in 1926, another plant pathologist named Eiichi Kurosawa identified the hormone in the fungus that caused the disease. (Melody Lee, 2010) Since then, over 130 additional Gibberellic acids have been identified from other fungus and numerous vascular plants, as well as bacteria.…

    The intention of this experiment was to find out which of the two hormones, Gibberellic Acid or Brassinosteroids, would have the greatest effect on growth among our test subjects, the organism Arabidopsis thaliana. The results of this experiment were not as we hypothesized. Gibberellic acid proved superior in cell elongation, which can be observed by way of plant height. This was a rejection to our original hypothesis, as well as a contradiction to the study: “Interactions between…

    zeolite-like structure is well known as the prototype of a number of polynuclear transition-metal hexacyanometalates with the formula, Fe4Ⅲ[FeⅡ(CN)6]3 [1,2]. It exhibits electrochemical [3–5], electrochromic [6–8], photophysical [9,10], and magnetic properties [11,12]. In particular, the electrocatalytic property among these special properties enables the potential analytical application of electrochemical sensor using the PB-modified electrode [13,14]. The reduced form of PB is prussian white…

    mixture is made up of only one uniform. The ingredients of an Alka-Seltzer pill consist of 324mg of aspirin, 1625mg of sodium hydrogen carbonate, 965mg of citric acid anhydrous, dimeticone, calcium silicate, docusate sodium, sodium benzoate sodium saccharin, natural and artificial lemon flavor, natural and artificial lime flavor. Each Alka-Seltzer pill has 445mg of sodium and once an Alka-Seltzer is dissolved in water, it turns into bicarbonate which reacts with the hydrogen from the citric acid…

    You already know your pool has a pump, but do you really know what that pump actually does? You might be surprised! What Exactly Does a Pool Pump Do? Your pool pump is the heart of your pool and without it, it would die...so to speak. Just like a human heart, your pool's heart (the pump) only has one thing it has to do which is pump water. However, that one thing serves several very important functions, such as: • Pulls the water from your pool through the skimmers and drains. • Then it…

    Salts and molecules have similar characteristics, and many differences whether we can tell by first looks or not. Testing these two only supports the differences, and many structural functions cause these differences. Since salts are ionically bonded, they have different properties and functions compared to the covalent bonded molecules. Salts have a ionic bond, and we can confirm due to their electronegativity. As you move from left to right on the periodic table you would notice that…

    suitable N-protecting group for nucleosides (Sikehi et al., 2006 and reference theirin). A solvent-free reaction utilizing a simple low-energy ball mill apparatus was reported to convert the amino groups of nucleosides S.36, adenosine, 2-deoxyadenosine, cytidine, 2-deoxycytidine, guanosine, and 2-deoxyguanosine as well as some of their ribosyl O-protected derivatives, to the corresponding bis-N-Boc carbamates S.37 (Sikehi et al., 2006). For guanosine compounds, the carbonyl group of the base…

    than anything else. It is important to take care of the body from any harm. One thing that the body is capable of is maintaining pH levels and buffers. A pH is the power of hydrogen and buffers prevent extreme shifts in pH. The blood has a specific type of buffer that is maintained at pH level of 7.4. If the buffers shifts and levels of pH go to 7 or 7.8, it can be deadly. The blood buffer contains carbonic acid which dissociates into bicarbonate acid and hydrogen ions. This equation can also be…

    The Rf values were obtained by reacting the lipids on the TLC plates with iodine, to visually show how far the lipids moved up the TLC plate. For the identification of the amount of lipids in milk, the milk was combined with an organic mixture of CHCl3/MeOH, to isolate the lipid layer. By centrifuging the organic solvent with milk the heavy lipids sink to the bottom while the water layer which contain water soluble carbohydrates, peptides and small amino acids float to the top. Since the organic…

    Freshwater Treatment for Amoebic Gill Disease Freshwater treatment for AGD requires checking for few things before and during the treatment to carry out a successful and effective treatment. 1. Freshwater Source: The freshwater source should be checked for temperature, total ammonia nitrogen and ammonia percentage, pH, hardness, salinity and any harmful plankton. Temperature: Freshwater with temperature closer to the temperature that treating fish are being reared in is best choice. Colder…
