With your spoon move the rice in a circular motion. Keep stirring until rice is a golden color. When the rice is golden, carefully remove the pot from the stove and set aside. Get your blender; add about four whole tomatoes from the can, ¼ of an onion, and 1 cup of water. Cover the blender with a lid and blend for 1 minute.
DNA Extraction Aim: To extract DNA from a carrot using house hold products. Method: * Step 1 – Pour 60 ml (¼ cup) of clear alcohol into a glass. Place the glass into the bowl of iced water to chill, then set aside. * Step 2 – Pour 120 ml (½ cup) of tap/distilled water into the measuring cup with the salt. Add 30 ml (2 tablespoons) of clear detergent and mix carefully until the salt is dissolved.
If the frosting starts to set then put it back over the pan of water for a couple of minutes, stirring until it becomes smooth again. * Spread over the remaining frosting over the top of the cake and then cover with sprinkles. * If you prefer a cake with slightly firmer frosting (like I do), then place the cake in the fridge for 15 minutes before serving. * Serve and
12 Mung Beans (6 per bottle) 10 Ml of water per bottle per day. A ruler to measure your plants each day. (cm) A data table to collect all the data you gather over your 10 day time period. Procedure: Follow the following steps: Step 1- Get 2 clear 2 liter bottles. Step 2- Clean out both 2 liter bottles for any excess soda, water, etc.
The Effects of Temperature on Beet Cell Membranes Introduction: The function of a cell membrane is to protect the cell and act as a barrier between the cells cytoplasm and its surrounding environment, and also to monitor the substances that move in and out of the cell using selective permeability. The cell membrane is primarily made up of phospholipids and proteins that form a bilayer. The membrane protects the structures inside the cell including the vacuoles that contain betacyanin, the reddish pigment in the roots of the beet plant. The vacuoles are surrounded by a membrane called the tonoplast. Betacyanin will leak from the vacuoles and pass through if there is damage to the membranes.
Materials & Methods Materials: · Scale · 4 6” Dialysis Tubing · 4 Transfer Pipets · Sugar · Scissors · Rubber Bands · 4 Same-Sized Coffee Cups · 250ml Graduated Cylinder · Tape Measure · Sauce Pan · 3 600ml Containers · Plastic Covering · Spoon Methods: 1.) Place 4 6” pieces of dialysis tubing into coffee cups full of tap with and leave them for two hours prior to beginning the experiment. 2.) As you wait, prepare your three sugar solutions. For the first solution, pour 5 grams of sugar into 250ml graduated cylinder and add water up to the 250ml mark.
Add 0.2 ml of yeast invertase and incubate at the same temperature for 6 mins. After incubation quench with 8.0 ml of 0.1M H2SO4 and mix thoroughly. Transfer 0.1ml aliquot of sample to a separate test tube and add 0.9 ml of H2O followed by 4ml of WSG and incubate at afore mentioned temperature for a period of 15 mins. The mixture is then assayed at 500nm. Procedure is to be repeated using temperature of 0o, 60o, and 80o C. Introduction Enzymes are single-chain or multiple chain proteins that act as biological catalysts with the inherent ability to promote specific chemical reactions in vivo, as well as in vitro.
The watch glass was removed with the beaker tongs. Using a rubber bulb and a stirring rod to stir the solution continuously, 15.00mL of .25M BaCl2 solution was added to the solution in the beaker. The watch glass is replaced and the solution is keep hot but not boiling for 15 minutes. The precipitate was allowed to settle. When the liquid above the precipitate was clear, the solution was tested for completeness of precipitation when a few drops of BaCl2 solution were added from a pipette.
We then shook the jar until it was well mixed and waited about thirty minutes for the mixture to settle. Once it settled we measured the thickness of each layer of the soil. In the water holding experiment we simply filled a beaker with 100 ml. with garden soil then poured water into the beaker to saturate the soil enough so that there was no air trapped in the dirt. We measured the amount of water we used and calculated the pore space as well as the percentage of pore space.
Do this one more time the exact same, and then a third time using only 10 mL of the mixture. Each of the three times you do this, extract the liquid. Transfer the liquid into the large 100 mL round bottomed flask that is connected to your simple distillation set up. Distill the tomato paste liquid. Once it is completely distilled, remove your filtered material and add 2 mL of dichloromethane.
