Depolarization is to excitation, while Hyperpolarization is to inhibition.
Option 4 is correct.
Hyperpolarization is opposite of Depolarization.
Depolarization is a process by which cells undergo a change in membrane potential. It is a process of shift in electric charge that results in less negative charge inside the cell.
Hyperpolarization is when the membrane potential becomes more negative at a particular spot on the neuron’s membrane.
Follicle cells in your scalp assemble proteins to build new hair. This most likely involves dehydration synthesis reactions.
Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule. Amino acids connected via peptide bonds form a polypeptide chain, which then chemically interact with other polypeptides in order to create a complex three-dimensional structure of the protein.
Answer: Option E.
A,B and C are correct.
