Discuss why maintaining plasma osmolarity within normal limits is important

The reason why it is important to maintain plasma osmolarity within normal limits is because it is important in the cell in which it contributes to their components of maintaining the volume and its excitability. Without its normal limit, it could interfere with the cell’s excitability and the volume could not be within its normal range. Plasma osmolarity also contributes with the blood pressure, if this does not follow the normal limits, it could produce high or low blood pressure.

idk lol use google m8

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
