Place a clean funnel into the mouth of a 250ml volumetric flask. 9. Carefully pour the oxalic acid crystals into the funnel. 10. Use the wash bottle with deionised water to transfer all the oxalic acid crystals from the glass beaker to the funnel.
Genetically modified crops are the leading agricultural food products not only in the Philippines but, mostly worldwide. It is now known that there are several mechanisms for DNA transfer. Genetically modified food are plants that have been generated in a laboratory by altering and changing their genetic makeup and have been tested in the laboratory for aimed qualities .This is usually done by adding one or more gene(s) in a plant’s genome using genetic engineering techniques. Plants are modified for insect, fungal, viral or herbicide resistance, for changed nutritional content, improved taste, and also for improved storage life. Genetically modified organisms is an organism which genetic materials had been altered using different genetic engineering techniques.
(Concentrations can be seen on Table 1. Pg 25a) Auxin is an important plant growth regulator (plant hormone), and it’s quite powerful so it can be active at very low concentrations. For this experiment we used a synthetic Auxin called 1-Naphthaleneacetic acid (NAA). Auxins tend to inhibit the outgrowth of axillary shoots, and tend to promote the formation of root meristems. Cytokinin is another important plant growth regulator, and along with Auxin both of these hormones are very important in plant development.
Business Technology Early College High School Fertilizer Lab Experiment AP Living Environment Mr. Acquaotta/Mr. Lee Purpose The purpose that this lab was conducted was because we wanted to see if seeds germinated faster if fertilizer was applied. Introduction Fertilizer we use it when we garden, we see companies promote it in various ways, but have you ever wondered if it made a difference in growth of plants? Does it really make flowers bloom more rapidly or vegetables grow larger and more productive? The answers to these questions are all within the realm of science because they are testable by controlled experiments, observations and data gathering.
One of the focuses of this semester was the ability to identify biological processes that require energy and explain why they require energy. In the work I completed I demonstrated being able to accomplish this. This occurred in several different projects, including the cellular respiration lab involving the respiration rate of germinating seeds, the potato core lab and the photosynthesis lab. In these labs, we were able to identify the biological processes that required energy for the different processes to take place to allow germination to occur. As the main focus of all of these labs was testing a
We then used a small mortar and pestle to crush the aspirin and we placed the resulting powder into a conical flask, we crushed the aspirin tablets so that I would be easy to mix with the ethanol. We then added 5ml of ethanol using a measuring cylinder and covered the flask with a watch glass, we did this to avoid evaporation. We then gently heated the mixture over a water bath of around 60-70°C and swirled frequently, we did this so that it would dissolve the acetylsalicylic acid. We then filtered off the hot solution to remove any insoluble material in another small conical flask, we rinsed the flask with a few ml’s of chilled ethanol to collect any residue that was left on the flask. We then slowly added 25ml of chilled deionised water to the filtrate to initiate crystallization by using a measuring cylinder and a dropping pipette, once we had done this we left it for about 10 minutes to allow crystallization at room temperature.
Roles of each consist of the nucleus contain genetic material, which controls the actions of the cell, the cytoplasm is where the most chemical process happens and I controlled by enzymes. The Cell membrane controls the flow to and from the cell, the Mitochondria has the most energy released by respiration. In the Ribosomes protein synthesis occurs, and in the extra parts of the plant structure is functions like the cell wall, which strengthens it. The Chloroplasts contains chlorophyll, it absorbs the light for photosynthesis, and finally the permanent vacuole is filled with cell sap that helps keep the cell
Many scientist today cut portions of DNA with restriction enzymes and include a piece of new genetic material into the bacterial cells. The only way this transformation can take place is if the bacteria is competent and is grown to the right stage in which they are dividing the most. In order for this to happen,one would treat the bacterial cells with Calcium Chloride (CaCl2). The bacteria used in this lab was E.Coli and it was an ideal bacteria because it can be easily grown on agar. Hypothesis The transformed E.Coli with the ampicillin resistance gene will be able to grow in the ampicillin plates and it would have a green glowing color.
Once the cola starts to boil, continue to boil it for another 10 minutes so that the carbon dioxide is removed. When the cola has finished boiling, cool it in an ice bath and pour the cola back in the volumetric flask and use distilled water to fill the flask to compensate for the evaporated water. Using a volumetric pipette, transfer 60ml of the cola to a beaker and put the magnetic stirrer in the beaker. Submerge the conductivity probe in the cola. Fill up the burette with NaOH
Fungi have pathogenic capebility for the biodegradation of undesirable materials or compounds and convert them into harmless, acceptable or useful products. Various fungal strains are known to degrade a wide variety of recalcitrant compounds, such as xenobiotics, lignin, and dyestuffs, with their extracellular enzymes. Many studies have also demonstrated that many fungal strains are capable of degrading various types of synthetic dyes such as azo, triphenyl methane, polymeric, phthalocyanine and heterocyclic dyes (Chulhwan et al., 2004). Many researchers used the lignolytic and nonlignolytic fungi for the decolorization of dye wastewater. The lignolytic white rot fungi are known to be the most efficient microorganisms for dye degradation.
