 * This week we learned about pH: percent of Hydrogen ions. I learned that red is a very strong acid 2.0; and blue or purple are very strong base10.0 is the lowest. pH is a fun subject and I actually used it in my science fair project but I didn't know what it meant.

 * This week I learned about coevolution and symbioosis. Sybiosis is a close, long term association between two or more species. Coevolution is when a long term change takes place in two species because of their close interactions with one another. I did not learn about these two things last year so it was interesting learning about them.
 * I learned that ribosomes were not only attached to rough er. Ribosomes float freely and are attached to rough er. I thought that they were just attached to rough er.
 * I also learned that the golgi complex paakages and distributes protiens. The golgi complex was named after Camillo Golgi, the Italian scientist who first identified the organelle. The golgi complex is one of the bigger organelles in the cell.

 * I dont get how the mitochondria works in the cell. Or how it can effect the cell. I would like to learn more about the mitochondria.
