Not happy about the last marking period and my grade :(. But working hard this marking period to get at least C. In class we start talking about Enzyme and Catalysis and had a lab for it. I learned how the pH, temperature, and the concentration effect the enzyme. the lab was fun and class is good so far :). Hopefully the next lab be fun too!.

In AP Bio class, we had Lab Activity about Osmosis and Diffusion. I learned that Osmosis is the movement of water molecules from high concentration to low and its different form Diffusion because Diffusion is the movement of molecules from high to low concentration . I also learned that if a cell is hypertonic  the water rushes into the cell, causing it to expand. If its hypotonic it loss water casing to shrink. But if its isotonic its the best condition for the plant cell between all of them because the amount of the water and the salt is balanced. To determine the water potential of a solution is by calculating the osmotic potential when the pressure potential is zero. Thats what I have learned from the lab and class lectures in the first 2 weeks of the new marking period.
