Aeration

1. Observation. - Compound X is a white powder. It is a solid. 2. Questions. - What is compound X? - What will happen when compound X is heated and reacted with C20H14O4 (phenolphthalein – an acid-base indicator)? (1) - How does compound X react with C20H14O4 (phenolphthalein)? (2) - How does compound X react with water? (3) - How does compound X react with hydro chloric acid (HCL)? (4) 3. Predictions. - Compound X is calcium carbonate (CaCO3). - (1) When compound X is heated and reacted with…

water clumps are shaken into larger clumps called flocs. Next, the water has to stand for twenty-four hours which allows the clumps to settle to the bottom. Then, the water is filtered and disinfected with chlorine. Finally, the water goes through aeration which helps remove certain contaminants (How Water…

The purpose of this lab was to test for which soil type would be best for food production. The tests included Forest Soil, Floodplain Soil, and Garden Soil. We predicted that garden soil will have the best properties for food production because we expected it to have the highest value of nutrients for plants to grow in and a soil composition that is fit for food production (ex. Water Holding, etc). To test our hypothesis, we ran tests measuring Percent Water Content, Organic Material, Nitrates,…

Recently, Betta splendens, otherwise known as bettas or Siamese fighting fish, have grown into one of the most popular ornamental fish (Monvises et al. 2009). More and more fish enthusiasts are adopting betta fish, meaning the fish are being kept in aquariums away from their evolutionarily fundamental habitats. These fish are originally from rice paddies and swampy areas in Thailand and other Southeast Asia countries (Jaroensutasinee and Jaroensutansinee 2001). Consequently, they have evolved in…

The motivation behind this experiment was to gain insight behind the theory and practice of two laboratory techniques: solubility-dependent extraction, and recrystallization, in an effort to isolate and identify three compounds originally dissolved in a mixture. Extraction is used to isolate a specific compound. Recrystallization involves taking a crude compound and removing unwanted impurities so that a more accurate melting point can be taken, leading to a more precise identification of a…

Antibiotics were a pivotal discovery which saved many lives during epidemics and pandemics over the recent centuries. During the 1920’s a scientist named Alexander Fleming was working as the professor of bacteriology in London at St. Mary's Hospital. Alexander was working on staphylococcus and had left some on the table which got contaminated. Later a colony was spotted in one of the samples resembling a white fluffy mass which multiplied rapidly and caused the staphylococcus to become…

is largely made possible by it’s rapidly developing tech options that facilitate easier ways to keep track of the fish, better gene selection and splicing, more effective containment systems, more efficient creation of and distribution of feed and aeration systems(Food and Drug Organization of the United Nations(FAO)). More accurate and in general better methods of measuring water temps along with other elements as pH and nitrate levels is also necessary in how biologists and engineers can work…

Deciduous Tree Grafting Introduction The Apple Tree, or Malus pumila, is a deciduous tree in the rose family that is best known for its pome fruit, the apple. The most widely cultivated tree within the genus Malus, the Apple Tree has been grown for thousands of years in Asia and Europe and was brought to North America by European Colonists in the 17th century. In 1625, the first apple orchard in North America was planted within the Boston area by Reverend William Blaxton. Typically, a…

Pre and post amputated images were collected and length was measured using scale. 250ml capacity beakers were taken. Upto 150ml filled with fish water which is suspended with the drug, fish were kept in them, one fish per beaker with continuous aeration. Test drug, standard drug (Imatinib) and control were given to each group respectively. Dose for test and standard were determined from the toxicity value [17]. On every alternate day, water was refreshed with the dose up to 15…

Marijuana should be legalized in the United States on a federal level for all purposes. Regulating marijuana as a crop would help maintain the environment. Economically, marijuana would help to boost revenue in the U.S. Marijuana also has numerous successful uses in the medical community. The United States has yet to legalize Marijuana, and this holds back the potential growth and protection of the environment that marijuana cultivation should offer. Marijuana is disregarded as being…
