After viewing the video on TedEd, it talks about how every cell in your body is seperated from those around it by its most outer layer, the membrane. Two scientist designed an expirement meant to test whether cell membranes are made with one layer of lipids, a monolayer, or two layers stcacked on top of one another, a bilayer.
There are lots of levels of homeostasis in an individual cell. Homeostasis is the process of keeping a human internal body environment at a certain temperature. It is specifically used to describe a living organism, which means that when your body temperature is to high and you're to hot, you sweat. Also, when your body temperature is to low and you're to cold, you get goosebumps. There are seven levels of homeostasis. The seven levels of homeostasis are smooth muscle in arterioles, sweat glands, errector pili muscle in skin, skeletal muscles, and adrenal and thyroid glands. All these levels of homeostasis have a part they have to do and complete.
In bio class we learned about cells. In this 3-class lesson I have learned a lot of interesting facts about the cell. One thing I learned in this 3-class lesson is, a vacuole is a organelles in the cell that is a storage area for the things the organelles need inside. The vacuole has no or internal structure. The vacuole is in the center of a plant cell.
There are organelles all over inside your body. Organelles are in our cells which are in our body. The organelles help out the cells just like the cells help our body. Organelles are not considered alive because, alive things need to reproduce. We have body parts that aren't able to reproduce because it isn't possible. Body parts like your ears, nose, eyes, mouth, legs, and arms are not able to reproduce, organelles are considered not alive because they are just like the body parts that were just named. Organelles can't reproduce, only cells can, which make other cells with organelles in them. All organelles also can not grow. When your body grows, the cells don't grow along with your body, the cells just reproduce to make more cells. Once you grow the cells reproduce and create other cells with organelles
After watching the lesson video, I have learned a couple new things. I had already read about some of the things. On the other hand it was interesting learning the other things I didn't know about. I learned that when Hooke was looking through a microscope at a cork, he saw little chambers that reminded him of cell rooms, or like the rooms monks stay in. Also I learned that there is actually bacteria on your teeth if you don't brush them
In this 3-class lesson, I have watched other students prezi or keynote presentation on, "What Does it Mean to be Alive?" and I took notes on things that I saw on other presentations that i hadn't have on my presentation. I have learned that not every living thing does not need to be living by cells, reproduction, consuming and using energy, responding and adapting to environments, growth, and levels of organization. I also have learned that some living things don't need to be living from all the levels of organizations.
In this article, it was talking about a team named, Venter's Team have been working on a virus called synthetic bacterium. This team was careful because if they were doing an important lab and messed up, anything could happen, whether its good or bad. They were prepared for anything that happened. What this team was working on was creating life. The group believes that there is something unique and powerful about life.

I learn that if you try anything to harm them, they will die, but then they will start coming back alive because they are strong little chemicals.
