Ap Biology Lab 9: For this experiment, what were the independent variable and the dependent variable?
How to Write a Summary of an Article? Ap Bio Lab One: Because all molecules have kinetic energy and are constantly in motion cells go through a process called diffusion. Diffusion is the movement if molecules from an area of higher concentration to and area of lower concentration.
We will write a custom essay sample on Ap Bio Lab One: Osmosis is a different and unique kind of diffusion. Osmosis is the diffusion of water through a permeable membrane.
In Osmosis water will travel from an area of higher water potential or an area of lower water potential. I think that in this lab, osmosis and diffusion will occur between the solutions of different concentrations until a equilibrium is reached and there is no movement of water.
Diffusion The materials include a cm piece of 2. Osmosis The materials used include mL of these solutions: Water Potential The materials that were used included 50mL of distilled water, 0.
Calculation of Water Potential from Experimental Data This exercise required a calculator and a pencil. Soak the dialysis tubing in water before you start the experiment. Tie off one end of the tubing to form a bag like structure.
Through the open end of the bad, place the starch solution in to the bag. Tie off the other end of the bag to secure the substance inside. Make sure to record the color of the solution in Table 1. Record the results in Table 1.
Record the color of the solution in the Table 1. Put the bag in the cup full of the solution. Allow the bag and cup to stand over night. The next day record the final color of the solution in Table 1.
Finally test the liquid in the cup and in the bag for the presence of glucose. Record the final results in Table 1. Get six strips of presoaked dialysis tubing and create a bag like was shown in exercise 1A.
Pour 25mL of the six solutions into each of the six bags. Tie off the other end of the bags.

|Ap Biology Lab 1 Report||Diffusion is vital to many life functions of a cell, it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion, it is as if a bottle of perfume is opened at one end of the room, then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion.|
Rinse each bag gently with distilled water and dry the outside of the bag with a paper towel. Weigh each bag and record the results in Table 1.
Put each of the six bags into the cups with the six different solutions. Let stand over night. The next day remove the bags from the water and carefully dry the bags with paper towel.
Weigh each bag and record them in Table 1. Pour 50mL of the solutions into a labeled mL cups. Using a cork borer, cut the potato into 24 cylinders. Record the data in Table 1. Put 4 potato cores into each solution cup. Cover the cup with a lid to prevent evaporation.AP Biology August 23, Egg Osmosis Lab Definition of osmosis: The diffusion of water across a selectively permeable membrane from high to low concentrations Hypothesis: If I place an egg in vinegar, then the outer layer of the egg is going to become slimy and look like rubber.

Introduction: Biology Lab on Osmosis Essay Michelle Kim As we age, our bodies change significantly.
Some of the effects of aging are quite apparent. For many, the skin loses its elasticity, the hair begins to turn gray, and mobility becomes much more challenging.
