The statement that describes the difference between the 2 isotopes of nitrogen would be the last set.
Nitrogen-14 has 7 electrons, 7 protons, and 7 neutrons
Nitrogen-15 has 7 electrons, 7 protons, and 8 neutrons.
Answer: depolarization; hyperpolarization
Explanation:
At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions.
However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs.
An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.
They are not able to reproduce independently
