===__ Week Five __ **This week I learned about dry ice and liquid nitrogen. Dry ice's boiling point, and freezing point are the same. So there is no liquid state involved. It goes straight from solid to gas, which is called sublimation. With liquid nitrogen it's a little different, it goes from liquid to gas with no solid state. __Week Fŏũ®__ This week I learned that**===

Week 1 Here is my 2nd journal entry. This week I learn all of the parts of a cell. Again. Some other things that where brought back from the bowels of sixth grade are, cell theory, and kinds of cells. I forgot way more than I thought, I found out, because I got a 50% on the freaken test. i also was reminded that robert hooke was the dude who discovered cells. the two different kinds of cells that i relearned about are prokaryotes and eukaryotes. eukaryotes have nuclei, and prokaryotes do not.=====

**//__Week 2__//**
Well, I learned that the endoplasmic reticulum only packages and ships stuff INSIDE the cell, and the Golgi Complex ships out of the cell. Ya, that used to mix me up pretty bad on tests and all that.
