World War Two final reflection humanities

Over the course of the World War Two project, I have learned valuable skills that will help me throughout the rest of my high school career. One of the things that I learned from this project is about World War Two in general. I had no prior knowledge about the actual events that happened during the war. I learned about many important people that changed the tide in the war, and also read some civilian reports about when armies invaded their villages and cities. One of the craziest things that I learned about World War Two was how selfish, and influential hitler was. Controlling the largest monstrosity, the third reich.

I learned adaptability through the multiple struggles finding the person I wanted to do the
Project on. In the beginning I wanted to do hitler, because the battle of Berlin was when hitler committed suicide. But, after getting some help, I learned that one of the most influential people in the overtaking of Germany was Joseph Stalin. Berlin was the final push to end the war, and he made sure it was done well. Sending his troops to encircle the Berlin, then collapsing on the remaining German army.

Lastly, I learned how to analyze. I had to read many articles on how and what the battle of Berlin  did for the war, and the people of the world. There were many resources which all had very different sides, some being bias. Learning how to take all of the information given, and turning it into valid information was what I learned from this project. For example, I read journals of people in Berlin when it was taken over. They called the soviet soldiers savages. On the other hand, the solver soldiers said the exact same thing about the Germans. This led me to understand what both sides of the war thought about each other, which helped me further understand all aspects of the war. All in all, this project taught us students thoroughly about World War Two, and the influential people that changed the tides of the war.

MITOSIS - WHEN CELLS SPLIT APART
Eventually cells need to duplicate. There are two main methods of replication, mitosis and meiosis. This tutorial will talk about mitosis.

The big idea to remember is that mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same. You get the idea.

Beyond the idea that two identical cells are created, there are certain steps in the process. There are five (5) basic phases in the life-cycle of a cell. You should remember the term PMATI (pronounced PeeMahtEee). PMATI is the acronym for the phases of a cell's existence. It breaks down to.

Events during Mitosis
Interphase: Cells may appear inactive during this stage, but they are quite the opposite. This is the longest period of the complete cell cycle during which DNA replicates, the centrioles divide, and proteins are actively produced. For a complete description of the events during Interphase, read about the Cell Cycle.
Prophase: During this first mitotic stage, the nucleolus fades and chromatin condenses into chromosomes. Each replicated chromosome comprises two chromatids, both with the same genetic information. Microtubules of the cytoskeleton, responsible for cell shape, motility and attachment to other cells during interphase, disassemble. And the building blocks of these microtubules are used to grow the mitotic spindle from the region of the centrosomes.
Prometaphase: In this stage the nuclear envelope breaks down so there is no longer a recognizable nucleus. Some mitotic spindle fibers elongate from the centrosomes and attach to kinetochores, protein bundles at the centromere region on the chromosomes where sister chromatids are joined. Other spindle fibers elongate but instead of attaching to chromosomes, overlap each other at the cell center.
Metaphase: Tension applied by the spindle fibers aligns all chromosomes in one plane at the center of the cell.
Anaphase: Spindle fibers shorten, the kinetochores separate, and the chromatids  are pulled apart and begin moving to the cell poles.
Telophase: The daughter chromosomes arrive at the poles and the spindle fibers that have pulled them apart disappear.
Cytokinesis: The spindle fibers not attached to chromosomes begin breaking down until only that portion of overlap is left. It is in this region that a contractile ring cleaves the cell into two daughter cells. Microtubules then reorganize into a new cytoskeleton for the return to interphase.
