Depolarisation
A membrane depolarization is a decrease in the potential difference between the outside of a cell and the intracellular medium, on either side of the plasma membrane, most often due to a positive ion input (Na +, Ca ++, etc.) inside the cell or sometimes due to the release of chloride ions, and involved in the mechanisms of transmission of nerve impulses and muscle contraction.
Hyperpolarization:
The depolarization is followed by a repolarization, thanks to the output of an equivalent quantity of ions k + which causes the return to the state of equilibrium. Then there is a hyperpolarization due to the output of more k + ions than Na + ions, because the potassium channels are slow to close. Finally there is a return to the resting potential.
Hyperpolarization is a term opposite to that of depolarization, it refers to values lower than that observed during the resting potential.
In diagnosing thyroid disease, thyroid function must be established first. This can be done by testing for the TSH, T4 and T3 in the serum. After testing for the thyroid function, ultrasound must be done, this can help us to visualize if the nodules are cystic or solid. Ultrasound can also help establishing the size of the tumor as well as if there is an invasion. FNAB can be done to determine the presence of malignancy, before doing this patient must be in euthyroid state. Hyperthyroid patient can lead into thyroid storm if FNAB was done without knowing the thyroid function of the patient.
Labeo = gills
Dolphin= pisces
Tadpole = hibernation

Human = mammals
Answer:
E. hepatic cells (hepatocytes)
Explanation:
These cells are the ones that secrete bile acids, rest do not match the given description
These cells make up about ~70-80% of liver mass and are primary authority at producing bile for the body
