Domoic acid

Overall, the experimental results were similar to the results needed to identify the cobalt ammine halide coordination complex. The color of the compound was dark purple and it looked just as expected as the experiments leading up to the collection of the synthesized cobalt compound had little to no errors. The percent yield of the compound was not 100% due to small errors throughout experiments such as losing some of the compound during transferring, more liquid evaporating than desired, and not

Eric Romohr 6CO2 + 6H2O + Light Energy ----> C6H12O6+ 6O2. Water corresponds with the light reaction, while Carbon Dioxide and Glucose correspond with the dark reaction. Hydrogen Atoms correspond with both of them. This wouldn't be accepted by an ap biology teacher because it is only partially right. Light is used, but so are water and carbon dioxide. It also doesn't use it as food, but rather to create food, or in those case glucose. An absorption spectra graph has 3 curves that show the wavelengths

pH and Biological Systems Introduction A characteristic of life includes homeostasis. Without a balanced pH in effect to uphold this characteristic, proteins in our body would be unable to function properly. This could in turn lead to physiological failure within the human system. Furthermore, an enzyme called amylase is present in saliva and is responsible for breaking down starch into sugar. A specific pH allows amylase to function. In this experiment we used iodine to see how pH affects the ability

The content of these tubes was then later transferred to separate small labeled beakers. The initial pH of the water in test tube A was then measured and recorded using a pH meter. Next. One drop and 1 mL of 0.1 M HCl was added to the water in test tube A, and the pH was measured and recorded. The pH meter was rinsed off each time it was used with distilled water and blotted dry. The initial pH of test tube B was then measured and recorded. Using a graduated cylinder and a pipette, 1 mL of 0.1 M

Mattresses usually release a musty smell into the indoor air and this can be quite unpleasant for all of us. Moreover, our sleep can be affected and we will find difficult to breathe as well. If you are in this sort of situation, then here is how to get rid of musty mattress smells. First of all, air the mattress outside This is the first thing you need to do, in order to obtain the desired result. Take it outside and leave it there at least for a day, if it is possible. It would be fantastic to

Tetrodotoxin (TTX) is one of the most potent low-molecular weight, non-protein neurotoxin known to block sodium conductance and neuronal transmission in muscles and nerves, leading to paralysis or weakness and possibly death if taken in sufficient quantity. It is also called puffer fish toxin for it is known to be the causative agent in puffer fish poisoning. It was first believed that TTX is only produced by puffer fish, predominantly stored and found in ovary and liver. However, puffer fish cultured

then the addition of zinc powder will reduce the nitrates in the medium to nitrite, changing the medium to a pink or red colour. I inoculated my bacteria into a tube containing nitrate broth, and waited until the next class day to add the sulfanic acid and N,N-dimethyl-1-naphthylamine. After adding the two reagents to my tube,

teacher 2. Place 1250 ml beaker containing 75 ml HCl underneath the buret (buret already set up with the volume recorded) for titration and apparatus. 3. Record the initial volumes of the acid and base to the nearest 0.1 ml and record HCl volume of 75 ml 4. Add 2-3 drops of phenolphthalein into your beaker of acid

ribbon was obtained and the weights of this ribbon was taken and recorded. There after a string also a certain length was wound around this magnesium ribbon. Next 100 mL gas measuring tube was partially filled wi an approximate amount of hydrochloric acid. The rest of the gas measuring tube was completely filled with water. Thereafter the string with the magnesium ribbon was suspended inside the

Commonly used food additives Monosodium glutamate –for enhancing the flavour however it is a harmul additive as it contributes to weight gain Sodium Cyclamate –artificial sweetener Sodium Benzoate-prevent oxidation of fats Benzoic acid-in fruit juices stronger against bacteria than on yeasts and mould Sulfites-for stopping fermination Nitrites and nitrates-for colour retention and inhibiting growth of bacteria Antibiotics-given to food
