10 ml NaOH was again added and mixed for 15 seconds to make lump free slurry. The mixture was stirred and allowed to stand for 3 minutes. An additional 10 ml of caustic soda was poured in the beaker and stirred for 10 minutes to mix thoroughly. In between the stirring, remaining 30 ml of 17.5% caustic soda was added at 2.5, 5 and 7.5 minutes in installments of 10 ml each. This mixture was allowed to remain in the beaker for 30 minutes further, making the total treatment time of 45 minutes from the beginning.
When the results for the first test tube were recorded, then the next solution/mixture was prepared. The second test tube was exactly the same as the first, the only difference being that the SPM was this time set to 35oC. The temperature of the SPM gets increased by 1oC for every test tube solution, until test tube 7 with an SPM temperature of 40oC. After all the absorbencies for the varying temperatures had been recorded – the product concentration of each test tube solution was calculated using the absorbency readings at 10 minutes for each respective test tube mixture. The product concentration was calculated using Beer-Lamberts’ law of A = ECL.
We started the treatments at 1:45 and ended at 2:45, giving the plants an hour to fully respond to their environments. After the hour ended we retrieved our plants and weighed them using the same scale, ensuring accurate measurements. We subtracted the final weights from the initial weights, getting the change of weight in milliliters (or the milliliters of water transpired). Next, to find out the total leaf surface area for each plant, we cut off the leaves of our bean plants and then traced them onto a piece of paper. We weighed the pile of paper leaves and multiplied it by the average weight of four/five sheets of 10 by 10 centimeters squared paper, which is .8192 grams.
We did this by finding our heart beat in our heart beat in our neck using our index and our middle finger. After we did this we set up our stepping stool which was twenty-three centimeters. Before starting we set the timer to zero. After we finished we recorded our time every fifteen seconds until our heart beat was back to resting. Then, we calculated our BMI manually.
The average egg size ranges from 120 – 130 um in diameters. Because of the short longevity of the sperm (about 30 minutes), the sperm is obtained shortly before fertilization. It is recommended to select the best quality sperm –based on motility and number- via microscopic examination using Sedwegick and Neubauer chambers. Fertilization: Washed eggs are transferred into containers of 10-12 liters whereas about a million ovules are placed in 1-um filtered and UV-irradiated seawater and at 17 – 18 °C. Fertilization is carried out by adding one ml of sperm solution with approx.
We repeated these steps until we got to the 100 meter mark, which took us eleven quadrats total. We also measured how far away from the shore it was at each quadrat. We took the elevation every ten meters. One person held the fiberglass staff and another person stood ten meters away and held the measuring pole. They moved their finger up on the pole until it was even with the horizon.
Twenty tablets were weighed accurately and powdered. An amount of the powder equivalent to 5 mg of amoxicillin trihydrate (content of one tablet) was dissolved in 60 ml of diluent. The solution was stirred for 10 min using a magnetic stirrer and filtered into a 100 ml volumetric flask through 0.45µ nylon membrane filter. The residue was washed 3 times with 10 ml of diluent and then the volume was completed to 100 ml with the same solvent. This solution was diluted with diluents to gae a concentration of 0.1 mg/ml solution each of Amoxicillin trihydrate.
Burette can actually transfers water more accurate compare to pipette and micropipette. The burette calibration were done using 5ml, 10ml, 15ml, 20ml and 25ml of water. Each volume of water was repeated three times to obtain a more accurate result. When the experiment is conducted, the mass of the empty Erlenmeyer flask is taken before each trial. For the nominal water volume of 5ml, apparent mass of water for Trial 1, Trial 2 and Trial 3 are 5.064g, 4.976g and 4.945g respectively.
s texting results First of all, in the cardiovascular health tests, I did the 1 Mile Walk Test in 15:35 minutes and my heart rate at the end of the exercise was 102 bmp/minute. This heart rate represents a very light stimulation. On the other hand, I did 1.5 miles in the 12 minutes-run with a final heart rate of 139 bmp/min. My heart rate was moderately stimulated during this test. As results, I had a VO@ MAX of 42.669, a population average of 37.295, a score of 84 and I was rated as “good.” Secondly, the muscular strength and endurance tests were: the plank (core strength) which was evaluated in 8 stages, the sit ups (30 seconds), the squats test, the push ups test and the standing long jump test.
To start an experiment of adsorption isotherm, Cu(II) aqueous solution of 100 ml with the predetermined varying initial concentration of Cu(II) in the range of 6.5-370.5 mg/l and the best activator composition of NaOH was put into the erlenmeyer flask and stirred using a magnetic stirrer at 75 rpm, room temperature of 298.15 K (± 2 K), 1 atm and normal pH. The experiment was stopped at 119 mins contact time for sampling. The samples of 1 ml were placed in a 20-ml vial and diluted with 10 ml distilled water, and filtered using a syringe filter. The filtrate was placed in 10-ml vial for the AAS analysis. To determine the concentration Cu(II) in the samples from the AAS reading, dilution factor was taken into
Called wash out). After 90 seconds a second washout occurs. At 180 seconds the length of the guinea pig ileum is reset to 2cm (note. The aforementioned steps are called the 3 minute cycle). Another dose of acetylcholine is added which follows the 3 minute cycle, however the concentration is increased by 1 x 10⁻⁸ M .
My payment is as discussed earlier of $100.00 a month. My formula would look like $100(((1 +0042^60) -1)/.0042) and that totals $6807.55. To get my interest it would be $6807.55-6000=$807.55 is total interest earned on the 5 years scenario. To get the interest I took my total amount subtracted the total payments to received that number. If I were to do this for 30 years I would take the same $100 a month at 5%, this time though it will be a total of 360 payments since it is 30 years.
Place C Elegans into the plates with the E Coli and leave for 24 hours. Examine the C Elegans to insure that the C Elegans have survived at the room temperature and continue to have multiple C Elegans surviving. Once this is done prepare the dilutions of all the subjects which we are testing. Start with 1% solution for Nitrate-N 100ml and move 10ml of the first well into the next. Fill the well with 90ml dh20 to reach 100ml.
The effect of the solution concentration of sodium chloride on diffusion in yam cores compared to the solution concentration of water Abstract The purpose of the experiment was to see if different solution concentrations had an effect on diffusion. Our group established a hypothesis that stated; sodium chloride will make the yam cores weigh less than in water. In order to start experimenting, we obtained 10 yam cores, weighed them and placed them in five cups that contained 50 mL of water. At 10-minute intervals, we would take them out and weigh them again for 30 minutes. We repeated this experiment using another five set of cups that contained 50 mL of 1M sodium chloride.
