Step 3: After, shell is removed, carefully remove egg from vinegar and place on a paper towel. Step 4: Record observations of the egg after vinegar. (texture, how it looks, etc……) Step 5: Get your triple beam balance and weigh the egg in grams (remember to place a paper towel underneath egg while weighing) Step 6: Record Measurements Step 7: Place an egg in a one of your 2 cups before placing egg name cup distilled water Step 8: Pour distilled water on top to cover the egg Step 9: Place plastic wrap on top of cup to cover the egg filled with distilled water Step 10: Now take your other egg from the vinegar used to take out shell. Step 11: Record observations of the egg after vinegar. (texture, how it looks, etc……) Step 12: Get your triple beam balance and weigh the egg in grams (remember to place a paper towel underneath egg while weighing) Step 13: Record measurements Step 14: Place the second egg in your second cup Step 15: Pour corn syrup on top of the egg to cover
According to diffusion, and the diffusion of water that has an impact of cells, which is osmosis spraying water on vegetables in a grocery store is beneficial because it prevents the vegetables from shrivelling up. In colder areas, salt is spread over roads to melt the ice. Explain what effect the salt would have on the plants along the roadside (in terms of osmosis and hypertonic & hypotonic solutions).
For each of the condition, about 35 milkweed bug eggs will be placed in clear container (5”x7”x4”) with a fine netting between the lid of the container and the container walls. The netting prevents the milkweed bugs from escaping while allowing for air to come in. Each container
The egg we experimented on went through many dramatic changes. In its original state, the circumference was 14 cm, and it was 66.8 grams in mass. However, it was much larger after it was put in the vinegar for 48 hours, the circumference was 17 cm, and the mass was 89.1 grams. This occurred because of osmosis. Since the vinegar had more water molecules than the egg, it was transferring the molecules to the egg to create equilibrium; therefore, the egg became larger.
After the egg remaining in vinegar for a few days, the size of the egg became bigger and there was less liquid left in the jar. Water moved into the egg because the egg was in a hypotonic solution that had a lower concentration of solute than the egg, water rushed into the
In this lab we used two processes called Diffusion and Osmosis. Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. Diffusion is a process that requires no energy and involves smaller non-polar molecules. In Figure 1 you can see the molecules spreading throughout the glass from the area of high concentration, so that the areas with low concentration are filled evenly as well. The other process was osmosis.
The number of drops was noted. The procedure, from the addition of NaOH to the noting of number of drops, was repeated for the other three beakers. The number of drops for the beaker labelled “tap water” was subtracted from the number of drops for the beaker labelled “tap water with Elodea” and
2. What process caused the egg to swell or shrink? Be SPECIFIC; discuss each liquid - Osmosis is the process that caused the egg to swell and facilitated diffusion caused it to shrink. Osmosis is the transportation
In this lab when looking at cells, we observed the salinity and osmolarity of the cell when placed in the environment. With the different concentrations of NaCl, we are able to see how different environment can constrain an organism and see the wide range of responses to regulate in cell’s osmolarity. The cells we studied was sheep red blood cells (erythrocyte), because they are the most studied membrane system and therefore used as ideal membrane to study the relationship between water and the passing of the different concentration of NaCl across the membrane. The purpose of the experiment was to observe the cell and infer which direction of the flow of the water due to the cell volume change.
