Answer:
Embedded in the lipid bilayer are large proteins, many of which transport ions and water-soluble molecules across the membrane. Some proteins in the plasma membrane form open pores, called membrane channels, which allow the free diffusion of ions into and out of the cell.
There are 6 molecules of O2.
"O2" is the formula for one molecule oxygen, which has 2 atoms.
The subscript (small) "2" tells you how many atoms are in the molecule.
The coefficient is the big number tells you the number of molecules.
In 6O2, there are 12 atoms in total (6 molecules of 2 atoms each).
Answer:
operates om the principle of temperature-induced resistance.
Explanation:
In physical quantities, the resistance of an electrical conductor can be correlated directly with the temperature of the material. The property for the change in the resistance with temperature is called the temperature coefficient of resistance. Mathematically, the resistance of a material is given as follows:
![R = R_{ref} [ 1 + \alpha (T - T_{ref})]](https://tex.z-dn.net/?f=R%20%3D%20R_%7Bref%7D%20%5B%201%20%2B%20%5Calpha%20%28T%20-%20T_%7Bref%7D%29%5D)
where R = conductor resistance at the temperature T.
Rreff = the conductor resistance at the reference temperature,
= temperature coefficient of resistance
T = Conductor temperature
Treff = reference temperature of the material.
From the equation, it can be seen that a positive coefficient for a material means an increase in the resistance of the material.
