In this experiment I attempted to created and study the affects of a egg in a hypertonic and hypotonic solution. To conduct this experiment I used the following materials: cups, eggs, vinegar, corn syrup, spoons and food coloring. To begin the experiment I placed three eggs in vinegar to dissolve their shells, leaving behind a thin membrane that allowed water to pass in and out of the eggs. The water molecules enter inside the eggs and the eggs begins to swell. Once the eggs have sat in the vinegar for two days I removed one from the vinegar, washed the eggs and placed it in the corn syrup.…
Discussions Bag A stimulates cell whose contents are hypotonic to its environment. The situation is because the concentration of the dissolved substances in the cell is less than the surrounding media. In this case, the cell contents contain 1% sucrose solution that is less concentrated than the 50% surrounding media. Therefore, a large concentration gradient develops between the two media. Consequently, because of the high concentration gradient, the bag loses water faster and this leads to its reduction in volume.…
These results show that the gummy bear was hypertonic compared to the pure water solution but was hypotonic to the 30% and 50% salt water concentrated solutions. Thus, in order to create an equilibrium in these solutions, water flowed into the gummy bear in the first solution and flowed out of the gummy bear in the other two solutions. In brief, the higher the solute concentration in comparison to the gummy bear, the more the water would flow out to create a isotonic solution due to the process of…
With the before and after measurements in two graphs, one can easily figure out that no matter which solution the bear is soaked in, it will increase to some extent. In tap water, the gummy bear started with a mass of two point eight grams and changed 217.9 percent to eight point nine grams. The volume of the gummy bear started off at 1,296mm^3 and change 617.6 percent to a volume of 9,300 grams (Table 1). In the cup is sugar water, the gummy bear went from a mass of two point seven grams to seven point three grams with a 170.4 percent change. The volume of that gummy bear increased by 420 percent by going from 1,350mm^3 to 7,020mm^3 (Table 1).…
Hypotonic: more within, the water will go according to osmosis. Isotonic: same amount on both sides, equilibrium. -When the egg was placed into corn syrup it was hypotonic and shriveled up and when it was in the water it was hypertonic and the water moved into the egg. Cell Membrane Research: University of Michigan studies show that in the beginning of the year cell membranes could be beneficial to alzheimer's treatment.…
Final Summary: Blue Sugar’s claim about the loss of merchandise which was ruined by water damage, could not be confirmed due to the lack of evidence to demonstrate that the water which flooded the area, caused enough water damage to ruin the merchandise in the boxes. The investigation never revealed any proof to show that the merchandise inside the cardboard boxes was either wrapped and protected with plastic to prevent a mishap as this from occurring. Even though there are no photographs to show the substantial amount of ruined merchandise had occurred, the amount of water which leaked underneath the floor board and into the store next to Blue Sugar demonstrates there was significant water flooding. Red Flag indicators: 1. There…
After each of the three tubes had turned red, and their turning time had been recorded, the tubes were transferred back to the rack and cooled. The final color changes were recorded. The last test tubes with samples…
The weight of the tube increased from 12.3 grams to 13.0 grams in 15 minutes; however, in the next 30 minutes, it decreased from 13.0 grams to 12.5 grams. The bag could have been weighed inaccurately before the weigh in by having water on the tube, or the scale itself, or the scale itself could have been misread. Since the bag was full of 10% sucrose and put in a beaker filled with 1% sucrose; the water should have rushed into the tube where the higher concentration was making the tube swell. The results of bag D supported my hypothesis that the water would rush into the tube where the higher concentration was; therefore, the tube would be hypotonic, and the tube would swell.…
It was hypothesized that if we place an egg in a low sucrose solution, then it will enlarge or swell, making it a hypotonic solution. The results of this experiment prove this hypothesis was correct. According to the results, as time increased, the weight of the egg also increased. This can be concluded because the low sucrose solution caused the egg to intact the liquid causing it to expand.…
The purpose of the diaper lab was to see if the concentration of solutes in a solution has an effect on the amount of liquid absorbed by a diaper. The experiment tested how well the diaper would retain liquids with a different solute concentration. The hypothesis driving the experiment was if a hypertonic solution is added to a diaper, then the diaper will be less absorbent because the water will be drawn out of the sodium polyacrylate (powder) in the diaper due to osmosis. Sodium polyacrylate is in most diapers and is toxic, yet incredibly absorbent polymer. Osmosis is the diffusion of water across a cell membrane.…
Determining The Process of Photosynthesis And Cellular Respiration Using Elodea and Yeast Introduction Photosynthesis is an essential process to life on earth, in which plants and other organisms use sunlight to create food from oxygen, and carbon dioxide. Cellular respiration is when energy in food is released and converted to ATP, which is then used as chemical energy to complete tasks within a cell. This process usually requires oxygen and releases carbon dioxide. Photosynthesis and cellular respiration are similar in some areas and different in others. The purpose of both of the process is to produce energy, but they have different ways of achieving this goal.…
By using these concepts and techniques, we created a dilution curve to display and understand our data. Procedure1 Materials The materials used in this experiment are whole grain cereal, Sodium Acetate, water, hydrochloric acid, 2-2 Dipyridyl solution, Hydroxylamine-HCl, and D.I. water.…
Discussion In this study, the Catechol enzyme was studied under the conditions of varying pH, temperature, substrate concentration, and enzyme concentration. In Figure 1, the data suggested that the trend was neither directly nor inversely proportional, but the highest activity rate was at 24°C. Most enzymes denatured at higher temperatures of approximately 40°C, which led to the inability to see any color change (Helms et al., 1998). At lower temperatures, the enzyme was somewhat efficient because molecules move slower at lower temperatures, so enzymes lost productivity.…
Over three days, we tested what would happen to an egg after leaving in various liquids over a 24-hour period. Before letting the egg submerge in vinegar overnight the initial weight of the egg was 66.6 grams. We thought that after leaving the egg in vinegar the shell of the egg would get softer. The independent variable is the vinegar and the dependent variable is the egg. We believed that the egg would be softer; because we saw the vinegar bubble once we put the egg in it.…
The two glasses is different with one is tall and thin while another one is wide and short. Then, we will start pour the juices into the new glasses in front of them. The children who lack conservation will state the juice with taller glass contain more water than other. (McLeod,…
