Osmolarity is affected by changes in water content, as well as temperature and pressure. In contrast, osmolality is independent of temperature and pressure. For a given solution, osmolarity is slightly less than osmolality, because the total solvent weight (the divisor used for osmolality) excludes the weight of any solutes, whereas the total ...
EnvZ is a sensor-transmitter that spans the inner cytoplasmic membrane and has historically been divided into two domains, the sensory and the transmitter domain. [3] [4] The protein is composed of a short N-terminal tail in the periplasm, two transmembrane regions with an intervening periplasmic loop, and a cytoplasmic domain containing the autophosphorylated histidine residue, which is ...
Quercus stellata, the post oak or iron oak, is a North American species of oak in the white oak section. It is a slow-growing oak that lives in dry areas on the edges of fields, tops of ridges, and also grows in poor soils, and is resistant to rot, fire, and drought. Interbreeding occurs among white oaks, thus many hybrid species combinations ...

Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life. Homeostasis is brought about by a natural resistance to change when already in optimal conditions, [ 2 ] and equilibrium is maintained by many regulatory mechanisms; it is thought to be the central motivation for all organic ...
