The ability of cells to communicate, that is, receiving and sending signals from and to other cells, determines the interaction between unicellular organisms and regulates the function and development of the body of multicellular organisms. For example, bacteria communicate with each other in the quorum sensing process to determine whether they are sufficient before forming biofilms, while cells in animal embryos communicate to coordinate the process of differentiation into various cell types.

Temperature and density share an inverse relationship. As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. If the temperature of water decreases its density increases, but only to a point. At a temperature of 4°C pure water reaches its maximum or peak density, cooled further it expands and becomes less dense than the surrounding water which is why when water freezes at 0°C it floats.
Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases. Various events can contribute to change in the density of seawater.
Salinity can decrease from the melting of polar ice or increase from the freezing of polar ice. Evaporation increases salinity and density while the addition of freshwater decreases salinity and density.
