Question
Color inside tubing Color inside tubing Color of glucose test Color of glucose test (before) (after) strip (before) strip (after) Clear ellow Blueire Explain what the color differences of the tubing AND test strip indicate. Was diffusion, osmosis or both observed in this experiment? (3 points). ections: Obtain a conical tube and complete the remaining steps INSIDE THE HOOD. Pour 2mL of DI water and 2.0mL of toluene inside your conical tube. Gently invert the tube a few times to ensure the products are mixed.Explanation / Answer
1.The cell membrane functions as a obstacle and a entry. It keeps enzymes, DNA, and metabolic pathways in one bundle while at the same time, discharges waste products and allows essential materials such as water to enter through it.
2.Semipermeable is used to describe a membrane that allows some molecules to pass through while blocking the passage of others.
In these experiments, we investigated the passage of materials through a semipermeable membrane by passive transport. This tubing allows larger molecules to pass through, but slowly. The movement of molecules from areas of higher concentration to areas of lower concentration is called diffusion.
3.Molecules pass through the cell membrane by processes that require the cell to expend energy (known as active transport) or by processes driven by kinetic energy of molecules (known as passive transport).
4..Osmosis is the diffusion of water molecules across a semipermeable membrane.
RESULT
1. Clear to purple means starting there is no diffusion and than slowly it take place net diffusion so the color is change .
2,Glucose test strip is yellow to blue due to iodine move to final solution due to diffusion.
