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 ...
This is due to urea entering the cell down its concentration gradient, followed by water. The osmolarity of normal saline, 9 grams NaCl dissolved in water to a total volume of one liter, is a close approximation to the osmolarity of NaCl in blood (about 290 mOsm/L). Thus, normal saline is almost isotonic to blood plasma.

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 ...
The economy has held up better than many feared, continuing to grow even after the Fed hiked the federal funds rate to a two-decade high in hopes of grinding down on inflation, which topped 9% two ...
Water supply pipes in unheated interior areas including basements, crawl spaces, attics, garages and cabinets. Those running against exterior walls that "have little or no insulation." This story ...
The first woman was elected to lead a country 64 years ago. Here’s a look at where, and when, women have secured national leadership positions since then.
