Summary

Within the cell, peroxisomes carry out several different tasks. One of their main jobs is to break down the hydrogen peroxide within the cell. H2o2 is a by-product of different enzymes in the cell, created by their activity. Since it is deadly to the cell, it needs to be rid of quickly. That's where the peroxisomes come in. The hydrogen peroxide ends up inside the peroxisome which contains an enzyme called catalase. In the presence of catalase, h2o2 will be broken down into oxygen and water. Other tasks that the peroxisomes carry out include digesting fatty, amino, and uric acids as well as digesting alcohol.

SP7: Arguing With Evidence

I engaged in an argument with evidence when I smeared other organelles in the cell war Edmodo campaign. To do so, I had to argue about why my group's organelle should become president of cell-land and provide solid evidence to convince others. For example, in one smear I made, I created a meme about the ribosome and why people believe the cause of Alzheimers Disease is related it. In addition to creating an entertaining meme, I had to do research on the cause, provide a brief explanation explaining what I am trying to tell others, and provide an informative source. Without evidence, my smear and meme would have no meaning. 

XCC: Stability and Change

The other day, while I was mountain biking I noticed how I was seeing more deer than usual. This reminded me of the deer, food, water, shelter, and mountain lion activity that we did last year in science. I figured what I saw was a real life example of the game taking place in Alum Rock Parks ecosystem. From what I have observed, I believe that the system there isn't stable. This is because of how many deer I saw. If the population of deer is increasing right now, it is probably because there is more resources for them and less predators like mountain lions. I also remember that in the game, when we graphed out the data that we found, the population of deer jump from really high to really low on a yearly basis. Right now, the population is probably in its high time. The reason why the population of deer changed like this was because of the resources. When there wasn't enough, deer were killed off in large quantities which left few deer. The few deer then had more than enough resources so they reprooduced in vast quantites and so on and so on. To make the population stable, I would recommend experimenting with the amount and combination of resources and predators to see what works best.
