    Exploring changes in Osmosis Abstract: In science, it’s said that cell tissue can be permeable, this means that the cell tissue can regulate what fluids or airs travel through the membrane. For a cell to be able to have that kind of attribute, it permits us to conclude that cell tissues contribute significantly in passive transport. Passive transport is the measure of constituents through the cell membrane minus any involvement of energy by the cell. This experiment was done in order to govern how osmosis occurs in two different substances. I placed a blotted deshelled egg in beaker A in 14% distilled water allowing it to sit for 10 minutes, 20 minutes and 30 minutes. I also placed another blotted deshelled egg in beaker B in 30% sucrose allowing it to sit 10 minutes, 20 minutes, and 30 minutes as well. Osmosis visibly happened because there was a change in mass in both of the eggs. The outcomes showed us that diffusion transpired differently for beaker A and for beaker B. For beaker A, the egg gained mass causing the egg to weigh more than it initially weighed before osmosis. For beaker B, the egg loss mass causing the egg to weigh less than it initially weighed before osmosis. Both eggs visibly went through change. One causing an egg to gain. My hypothesis was accepted because my results turned out to be accurate. I roused my procedure and was able to appropriately form a sensible conclusion. I used the characteristics of osmosis and it allotted me great results.…

    The hypothesis that if sucrose concentration is placed in one of the model cells then the rate of osmosis will increase was supported by the data in this study. To start with, the tap water without any sucrose concentration (M) started at 4.87g and ended with almost the exact same mass after 60 minutes had passed. On the other hand, when 1.20 M of Sucrose Concentration was emerged in water for 60 minutes and pulled out, its mass went from 6.48g to 9.03g.. Osmosis is the net flow of water…

    3.0 RESULTS AND DISCUSSION 3.1: Effect of Storage Conditions on Egg Weight Tables 1- 2 show the results of effect of storage conditions on eggs weight (chicken eggs and quail eggs). The weight of chicken eggs stored at ambient condition (control), moist sawdust, refrigerator and those that were dipped in oil reduced from 63.61-60.03g, 63.11-60.99g, 61.12-59.41g and 66.12-65.79g respectively. While the weight of quail eggs stored at ambient condition (control), moist sawdust, refrigerator and…

    When the egg was placed into syrup, a hypertonic solution, it shrunk in size. This result supports my hypothesis. The mass of the egg before it was placed in syrup and after it was placed in syrup changed drastically. There was a 16 g decrease in mass that happened to the egg during its time in the syrup. Both the long and short circumference of the egg decreased. The long circumference before the egg was placed in syrup was 18.75 cm and after it was taken out of the syrup the long circumference…

    EGG LAB ANALYSIS Bouncy egg trick: You turn an egg into a bouncy ball by leaving the egg in vinegar. on the first day we place the egg into vinegar which helps break down the eggshell. Vinegar is a acid which dissolves the eggshell, which is made of calcium carbonate, turning the shell to carbon dioxide. Vocab/ Relation Osmosis: diffusion of water Diffusion: molecules to spread out in order to occupy an available space, without using energy. *diffuse from high to low. -The egg was placed into…

    of the dialysis bag because its molecules are larger than the pores of the bag. Also, I2Kl will diffuse into the bag making the solution inside the dialysis bag purple in color. Furthermore, the purpose of experiment B of exercise 2 is to be able to identify the effects of a hypertonic, hypotonic, or isotonic solution cells. For instance, when a cell is placed in a hypertonic solution, the water moves out of the cell causing the cell to undergo plasmolysis. Plasmolysis is the shrinking of the…

    When the water potential of the solution is lower than the water potential of the cell, the solution is hypertonic because there are more solutes surrounding the cell rather than in it. Osmosis occurs as a result of this because water diffuses down the water potential gradient to achieve equilibrium. This causes the onion root to lose water because the water from the onion root cells move from an area of high water potential, out of the cell, to the solution that contains a higher concentration…

    When the first bag, which was made of distilled water (10 mL), was fully immersed into distilled water. Its mass almost did not change (Table 1). It increased from 11.9g to 11.3g after 15 minutes, but after it, the mass always kept in 11.3g during the last 45 minutes. For Bag 2, 10mL 10% sucrose immersed into distilled water, its mass increased with the time increased (Table 1). It showed that the weights increased 1.2g in 60 minutes. Also for Bag 3, which contained 30% (10mL) sucrose immersed…

    As seen in the (Fig. 3) it showed that water placed in the cells were filled with violet colored sap inside the cell (wet mount) It was turgid. This is because of water abundance in and out of the cell. After removing the water and replacing it with the 5% salt solution, the protoplasm shrunk away from its cell wall because the water molecules in the cell moved to a higher concentration (outside the cell). As seen in (fig. 4) it showed that half of the cell is empty because plasmolysis occurred…
