The influx of positive charges makes the membrane potential more positive and is known as depolarization.
<h3>
What makes the membrane more positive charge ?</h3>
The membrane potential normally becomes more positive in response to neurotransmitters that open Na+ channels, more negatively in response to those that open K+ channels, and vice versa in response to neurotransmitters that inhibit these channels.
<h3>What does polarization mean?</h3>
The orientation dispersion of the electromagnetic waves that make up light beams is referred to as polarization. Unpolarized (uniformly mixed orientations), linearly polarized (fixed orientations), and circularly polarized are some of the different polarization states that light can take on (rotating field about the line of sight).
<h3>How membrane is affected by polarization and depolarization?</h3>
At a specific location on the neuron's membrane, hyperpolarization occurs when the membrane potential increases, and depolarization occurs when the membrane potential decreases (more positive).

Chlorophyll is contained within the thylakoid membrane. Stroma is the space between the thylakoid membrane and the chloroplast membrane. The outer most part is the double membrane in which the whole chloroplast is housed. It is like the walls of the house.<span>Chloroplasts are surrounded by this double membrane and contain a third inner membrane which is the thylakoid membrane. This membrane forms long folds within the organelle. In electron micrographs, thylakoid membranes appear like stacks of coins.</span>
Diffusion is helping these gases to do the gas exchange at alveoli, and blood capillaries. And diffusion depends on partial pressure because it is the pressure produced by the gas in a mixture when it occupied by its own volume.
Explanation:
- In a body, the gas exchange will occur in two places, one is lungs where oxygen will take and carbon dioxide will release into the respiratory membrane. The second place the tissues where the oxygen is released and the carbon dioxide is taking.
- In external respiration, exchanging gases with the external environment and this occurs in the alveoli of the lungs. In the internal respiration, change of gases will happen with the internal environment and occurs in the tissues.
- The exchange of gases is happened because of the simple diffusion. Diffusion is the process at which the gas-particle will move from high concentration to low concentration.
- there is no energy required to move carbon dioxide or oxygen between the membranes. Because they will create a pressure gradient which allows them to diffuse between the membranes.
The answer to this is the plate tectonics theory.
The earth's lithosphere is divided into large, moving sections which are called the tectonics plates.
Hope this helped :)
Have a great day
