Please include between 1-2 paragraphs of response and include some context to explain your answer.
Let's say you are adrift in the Atlantic Ocean and, being thirsty, drink the surrounding seawater. Thinking about osmosis and the solute/solvent balance, what result might you see in your body and your cells?
In terms of evolution, what do the mitochondria inside your cells and the chloroplasts inside plant cells have in common?
Think about the way that water molecules interact with each other. At room temperature, water is a liquid. In your freezer, water is a solid. When you boil water and steam rises, water is a gas. What is happening to the bonds between the water molecules when water is frozen and when water is boiled that explains that change?
Several billion years ago, the very first cells on earth had to assemble themselves from their chemical components. This is relatively easy to imagine for cell membranes, because they're made of phospholipids which will form a small cell-shaped sphere just in the presence of water. What characteristics of the phospholipid molecules cause them to assemble themselves spontaneously into a "bilayer" when they're surrounded by water?
There are 20 amino acids that, when combined in different ways, make up all the proteins we need to live. If you were to look at the chemical formula for each of the 20 amino acids, you'd notice two parts of their molecular structure that they all share, and only one part of their molecule that distinguishes them from each other. Which part of the molecule is unique to each amino acid?
1. The chemical structure of the amino group
2. The chemical structure of thecarboxyl group
3. The chemical structure or property of the "R" group.
4. The number of amino groups on the molecule.

1. Water is essential for our body to maintain the physiochemical reactions, cellular structure, shape and fluidity of body fluids. To maintain the cellular shape, the cellular fluid named as cell plasma, has a particular osmolarity or isotonicity. This osmolarity or isotonicity is maintained or remained in equilibrium outside and inside of cell. When we drink salty water such as Atlantic Ocean or sea water that increases the salinity outside of our cells rapidly, this causes the movement of water outside from the cells through osmoregulation effect. The movement is continued till the equilibrium which lead to dehydration of cells and if remains for longer time will results in death/destruction of cells...
