Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms
The function that is NOT related to a protein is:
Membane fluidity.
Membrane fluidity is not related to a protein function because membrane fluidity is a function of lipids not proteins.
Transport and all other options are involved in functions of protein.
Answer:

Explanation:
Hello there!
In this case, since these problems about gas mixtures are based off Dalton's law in terms of mole fraction, partial pressure and total pressure, we can write the following for hydrogen, we are given its partial pressure:

And can be solved for the total pressure as follows:

However, we first calculate the mole fraction of hydrogen by subtracting that of nitrogen to 1 due to:

Then, we can plug in to obtain the total pressure:

Temperature is a measure of the average kinetic energy of the
particles in an object.
