To calculate the percent change in mass, use this formula: After leaving the potato cores to soak in the solutions for a whole day, take out the potato cores. Due to this, I would expect that the potato cores in the 0. It will, however, allow water molecules to go through the passages of the selectively permeable membrane due to diffusion.
To finish, share data with other groups and compare results among one another to obtain an average of all of the results. A The first step in this lab would be cut out four cores of a potato and measure the masses of each individual potato piece. In contrast, I would expect that the potato cores in the 0.
As a result of that happening, their percent change in mass will be positive. This can be determined by the usage of potato cores.
Considering this, the percent change in mass will be negative. This would ultimately make the potato cores in high sucrose solutions lose mass. This will help in seeing the sucrose molarity among the solutions.
A, B, C, and D. In osmosis, water moves through a selectively permeable membrane from a region of higher concentration to a region of lower concentration. Water molecules will be able to pass the selectively permeable membrane because there will be a lower concentration of water in potato then the outside, making the water flowed into the potato core.
The factor that makes these high sucrose solutions different is the result of having a high sucrose molarity. Leave the cores in the flasks for a day.
This selective membrane only allows certain types of molecules to flow through while other molecules are not able to.
Osmosis and Diffusion The purpose of this experiment is to decide which flasks correspond to the solute concentration of sucrose, which are 0. Measure the data results of the percent change of mass in grams.
Afterwards, calculate the percent change in mass. In diffusion, molecules are in constant motion and move from an area of higher concentration to an area of lower concentration. In the high sucrose solutions, such as the 0.
Ap Bio- Lab 1: By this happening, it would make the potato core gain mass.
How to Write a Summary of an Article? C Considering the principles of osmosis and diffusion, these would be reasons on why I have these high expectations of my results.
A controlled variable in this lab would be to pour a certain amount of sucrose solution from a flask into a breaker. This will verify that the results acquired were incorrect or correct.
The mass of the potato core would be a variable factor in this experiment. Measure the final mass of each potato core and record this data. In this experiment, the potato core will act like a selectively permeable membrane.
Next, put 1 potato core in each beaker: To show a visual picture of the percent change in mass, graph it.
A way that this variable can be manipulated would be each group would be assigned to a specific potato core mass. Having a high sucrose molarity will make the water from the potato cores move out.Name _____ AP Biology 2 of 16 LAB 2.
