Abstract The basic principles of Osmosis and Diffusion were tested and examined in this lab. We examined the percent increase of mass and molarity of different concentrations of sucrose in the dialysis bag emerged in distilled water and the potato cores emerged in concentrations of sucrose. The data reinforces the principles of Osmosis and Diffusion‚ and in a biological context‚ we can simulate how water and particles move in and out of our own cells. Introduction Objective: 1. Investigate

Even though Africa benefited from globalization‚ they mostly suffered from it. One of the benefits of globalization for Africa were the manufactured goods that were brought to them through the slave trade. These goods consisted of silver‚ strips of cloth‚ gold‚ and copper bracelets. On the contrary‚ Africa was the main source of slaves since they had already been exposed to tropical diseases and had built up an immunity. This came with several disadvantages. Firstly‚ the African population

sucrose than that of Beaker #2 so therefore the solution of Bag #1 was hypotonic and water moved into the bag from the solution of the beaker at the greatest rate because it had the highest difference. 3. What does this tell you about the relative tonicity between the contents of the bag and the solution in the beaker? The solution in Bag #1 was hypotonic in comparison to the solution in Beaker #2‚ which shows that the water from the solution outside the bag moved through the semipermeable membrane

Without altering the dish‚ the New York Strip was lackluster in the appearance department. It was as if the devil himself spawned in the kitchen of Claim Jumper and defecated onto a plate. Still‚ I relished the steak‚ dwelling on how the dryness and bitter taste cleverly allowed the accompanying green peas total dominion. Furthermore‚ the mashed potatoes were an excellent addition to top off this catastrophic dish. I despised the thin strips of potato skins left in the mashed potatoes. The mashed

AP Bio Lab Report Osmosis and Diffusion Introduction When a substance is released into an area‚ the random movement of its molecules results in a multitude of collisions. These collisions‚ in turn‚ lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration‚ where there will be more collisions‚ to areas of low concentration‚ where the number of collisions will be much less. This process of dispersion will continue until there is no

2ml microcentrifuge tubes‚ 2ml pipettes‚ and QuickStix Strip Tests.1 We first used the mortar and pestle to grind our food samples down to a fine powder weighing three to five grams. The powder was then put in a 50ml centrifuge tube with 40ml of deionized water to dissolve the powder. The 2ml pipettes were used to transfer a small amount of the dissolved sample to 2ml microcentrifuge tubes. The sample was then tested using QuickStix Strip Tests for the presence of proteins responsible for pesticide
