I put the water from soaking the bones in the slow cooker. Any veges, I threw in carrots, garlic, broccoli stems, celery. You could put in onions or leeks or even just use your left over scraps from veges in the week. Put them in 8 hours before the end. There is talk that if you put them in too early they soak up the minerals.
Once we read, we then obtained the materials needed, which were an electrical balance, a nickel, golf ball, pencil, rock, an empty 100 ml beaker and a 100-ml beaker containing 50 ml of water. After obtaining our materials, we turned on the balance and set it to weigh in grams. Then, we "zeroed" the balance and began placing each object on the balance. While placing each object on the balance, our lab partner, Sandra recorded the weights. Eventually, we finishing weighing each object, recording their weights and then we began converting the recorded measurements to the English system and calculating the density.
In this lab, we separated into individual groups to create our modified recipes. We each had two hours, and our ingredients premeasured, allowing for a quick start to our cooking process. Each kitchen had to change a recipe to have a lower fat content as well as, sodium, sugar, carbohydrates or another healthy alternative. After a brief discussion, we began cooking our modified recipes. The recipe I chose to modify was biscuits and cocoa gravy, a sweet treat that is high in sugar content but very filling.
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. We then weighed a filter paper which we will use later in the experiment. We then collected the crystallized acetylsalicylic acid by vacuum filtration in a Buchner funnel and washed the product with a little ice-cold water. We then pre-weighed a clean, empty watch glass and labelled it with our initials and the date, we did this do we could easily identify that it was ours when we go to weigh it with the crystals on. We
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.
The supernatant was then removed without disturbing the pellet. This process was repeated twice more until a total of 2.5 mL of cell suspension was removed from each culture and all the supernatant was removed from each micro centrifuge tube. The original protocol called for a total of 1.2 mL of cell suspension to be taken from each culture, but the laboratory staff determined that a greater volume was required in order to get a sufficient DNA concentration to be used for the DNA digestion. To each tube was added 200 μL Cell Suspension Solution, followed by vortexing until the pellets were completely re-suspended. Next 200 μL Cell Lysis Solution was added to each tube and then mixed
The highly unsaturated ones are the omega-3 fatty acids, but another lipid found in the cell membrane is cholesterol, and all the good cholesterol found in all your cells form a hydrophobic bond. The term hydrophobic refers to the water solubility of the cell membrane, phobic meaning “afraid of” and “hydro” meaning water. So, cell membranes are secured by hydrophobic bonds, since lipids aggregate in solution without actually attaching to the atoms that constitute the solution. Shake a bottle of oil and water, and the oil (lipid) aggregates together into smaller and smaller droplets, but it will never form bonds with the water. Leave the bottle standing, and the oil always separates from the water and rises to the top, because it’s lighter and will never form bonds with water (hydrophobic).
The aim of this experiment was to find out how many sugar did the potato include, how many sugar did we have every day by eating the potato. To know the sugar that includes in the potato we have to compare the mass of the potato before and after the experiment with different concentration of sucrose solution. We went through our procedure, put the result into the data table and calculate the percent change to the graph. And get the osmolarity bass on the graph we have. The mass of the before the experiment was ranged from 8.520 g to 18.46g.
While sautéing the vegetables add the minced garlic during the last 30 seconds. Once that is done you will add the 4 cans of chicken broth, tomatoes and cumin to the pot then stir with a large spoon. Season with salt and pepper to taste and add the sliced chicken breast. Bring the mixture to a boil over medium-high heat then reduce to medium heat. Cover with lid and allow it to cook for 10-15 minutes.
