In order to reduce the activation energy in a chemical reaction. a catalyst is introduced to lower the activation energy of a reaction, so that a chemical reaction can take place. However, by increasing the temperature of a reaction helps the effect in increasing the number of reactant particles that have more energy than the activation energy. Therefore, by reducing the activation energy, the reaction would go faster.
Answer:
This is because the voltage gated sodium channels which opens for the influx of sodium ions, which caused increased postivity of the axoplasm closed, with simultaneous opening of potassium channels.
Therefore depolarization stopped, thus propagation and transmission of action potential (caused by depolarization) which cause the reversal of charges in the membrane (making the axoplasm more negative) for the voltage rise to 40mV also stopped.
In addition the simultaneous opening of voltage gated potassium channels caused K+ to leave the axoplasm to the external environments. This makes the inner membrane to be negative further lowering the potential, to -75mv. This is re-polarization.
Explanation:
Beatrice is suffering from a disorder termerd as anorexia nervosa which leads to abnormal eating habits in a person which may negatively affect the person.
The answer is spin.
Each quantum number that describes the two electrons in a helium atom is identical, except for the one that indicates their spin.
