One unique characteristic of water is its ability to break down many materials. It does this by pulling apart the different materials. The water molecules will surround these materials and create a bubble to prevent the materials from finding each other again. When all the materials are secluded, whatever was in the water is fully dissolved.
The polarity of water results in hydrogen bonding between two water molecules. This is because each end of a water molecule has a different charge. The oxygen end has a more or less negative charge, while the two hydrogen's have more of a positive charge. This is why water is able to form hydrogen bonds. The ends of two different water molecules will attract to each other (seeing as opposites attract) and will want to stick around one another. They form the hydrogen bond so they will be much harder to separate.
Water is also used as a solvent, temperature regulator, and a lubricant. Let me explain. Water is a good solvent because it is able to pull away molecules from a solution and surround it entirely. This is why water is able to dilute so many different solutions. Water is a good temperature regulator because of how stable it is. Water has a stability range of 0(degrees) to 100(degrees). Water is incredibly resistant to temperature change. Finally, water is a great lubricant. This is because water disrupts friction. This allows whatever object is moving will be able to do so with great ease.

The Cell and its Organelles
I know and can describe many, if not all of the organelles and their functions. I know that the Nucleolus is the dark stained area in the center of the Nucleus. The Nucleolus is in charge of creating new Ribosomes for the cell. I know that the Smooth Endoplasmic Reticulum is in charge of making Lipids and Steroids. It will also detoxify harmful material and waste products.
I also know how some cell organelles work together with one another. I know that Ribosomes will make proteins that are carried by the Rough Endoplasmic Reticulum. The type of protein the Ribosomes make is decided by the Nucleolus.
I would also be able to tell what cell organelle I am looking at if I was shown a picture.

Homeostasis
I know the basics of Homeostasis so far. This includes what negative and positive feedback does in your body. I also know what Homeostasis actually means and does.
Homeo = The same
Stasis = To stay
Homeostasis is what your body does to keep you normal.
Homeostasis begins with a stimulus. This can be something such as a person getting too hot.
This is when the Receptor comes into play. The receptor will let your body know that something is wrong.
The Regulatory Center will then tell the Effector to make your body sweat.
The Response is that your body will sweat. This cools your body and lowers your overall body temperature. After you are cool enough, you will stop sweating and gain Normalcy.
I did not have a phone to take a picture of my poster so I grabbed this from the internet.
