Answer: Closed
Explanation:
At resting membrane potential( RMP) sodium channels remained shut, this is because , previously in depolarisation,the voltage gated sodium channels were opened for sodium to diffuse into the Axon. However these channels closed after reaching their refractory period,s.
Therefore a change in the extracellular concentration of sodium will not open them

<span>In the liver, bile salts
are formed. <span>Because
of their low surface tension, this contributes to the emulsification of fats found
in the intestine and their absorption from the GI tract. These are bile’s
components. It is because of the bile salts which give bile the ability to
emulsify, mix, lipid in the aqueous environment in the intestine. Bile is the
one responsible for the efficient digestion of lipids. Bile is secreted in the
gallbladder down to the small intestine. It then breaks dietary fats into
smaller particles called emulsification in the small intestine. The bile’s
function is in the completeness of the digestion and absorption of fat. </span></span>
