Water treatment

experiment using a water pump for the treatment group. To set up the experiment we used 2- plastic six-quart storage containers for the control and treatment groups. The containers each had tight fitting lids that contained 4 holes to place yogurt containers in each, with a total of 8 yogurt cups between both groups. Next, two small holes were drilled into each yogurt cup that allowed us to pull an 8” wick through the holes, the wicks were designed to be inserted into the water for nutrient…

ice and a cooling chamber was then prepared to be put under the microscope, by filling it with ice and a small volume of water. This was done to ensure the temperature would remain around 15 degrees Celcius, which could keep Daphnia magna efficiently cool. Furthermore, the different concentrations were prepared in separately labeled eppendorf tubes, by adding distilled water to the 50 mM of caffeine to dilute them to the appropriate concentrations chosen. The slides were then put on the cooling…

Osmosis: diffusion of water Diffusion: molecules to spread out in order to occupy an available space, without using energy. *diffuse from high to low. -The egg was placed into water and the egg expanded because of osmosis and diffusion. there was more water outside the egg so some of it had to go in. Active Transport:molecules spread against the concentration gradient. this uses energy, and requires help from carrier proteins. * moves from low to high.…

was the lowest when vinegar was added to these vegetables, numbers including a range from three to five. When the saucepan was covered and cooked in water for 15 minutes, it tended to cause the vegetables to be one of the mushier ones out of the other cooking treatments. Numbers ranged from five to seven compared to two with other cooking treatments. I expected this outcome with a covered saucepan, you get a softer texture with a lid on because it is trapping the energy compared to when it is…

Phosphorus: General: Phosphorus is one of chemical elements of periodic table with atomic number 15 and atomic mass 30.9738 g/mol. Phosphorus is one of members of polyvalent non-metal of Nitrogen group and can be found in nature as some different allotropic format. Phosphorus can not be found free in nature since it’s so reactive and while it’s isolated and pure, it is clear and almost transparent. Phosphorus can be found in three common forms as white, red and black which their particular…

is difficult to get rid of this problem, the continuous usage of some home remedies contributes greatly to its elimination. Here are the most effective remedies for blackhead removal at home. 1- Toothpaste Toothpaste is one of the most effective treatments for getting rid of white or blackheads. Put plenty of toothpaste on the affected areas and leave for 25 minutes and then wash your face well. You will notice the disappearance of the upper part of the blackhead. But it still needs some time to…

evaluate the hydration free energy of some electrolytic solutions and to study the nature of the solute-solvent interaction 5. The present work aims to determine the conductance values of sodium diethyldithiocarbamate (NaDDC) which have been measured in water at different temperatures (25, 30,…

population will have significant impacts on the environment such as ecosystem deterioration, water scarcity, unhygienic sanitation and other resource depletion (Dixon 2011). Focus on the water issue, increasing in the number of population has…

So many new inventions are created every single day, and some of them are powerful enough to change our world and the way we live. One example of this is the modern toilet, which was invented by Alexander Cummings. In order to keep the water at the bottom of the bowl, Cummings made the S-valve in 1775; this prevented smelly gas from coming into the home. From there on out, doing your business was one hundred times easier. Even though we sometimes take toilets for granted, they are one of the few…

Nearly three hundred people filled the tranquil water before me. Children splashed each other in delight, while adults preferred to just relax and float on the surface. However, this tranquil water did not last long, as a familiar noise known as “the buzzer” sounded. The buzzer signals the wave generator to begin producing ten to fifteen-foot-high waves. In this instant, each individual is considered to be at risk for injury and it is my job, as a lifeguard, to watch over and protect them. We…
