A fiber-rich diet is best for intestine health, so the option that says fiber is correct. In the intestine, there is a diverse microbiota that performs a lot of cellular activities and facilitates the digestion process.
<h3>What is the intestine?</h3>
The intestine is an organ located below the stomach that is divided into two sections: the small intestine and the large intestine. The small intestine is responsible for complete digestion, while the large intestine is responsible for minute digestion and the for removal of fecal materials (undigested food). Fiber-rich foods, such as beans, should be consumed in order for the intestinal system to function properly.

Answer:
( a ) Voltage gated channels - channel can open and close based on membrane potential. At rest, the channel is closed and it opens at threshold.
Explanation:
Voltage Gated Channels -
It is a channel with a cluster of proteins present in the membrane .
The function of voltage - gated channel is to open for the some values of membrane potential and close for others . In maximum cases , the relation between channel state and membrane potential is probabilistic and requires a time lag . The ion channel can even flip the conformations at an unpredictable times , the membrane potential even determines the rate of transition and the probability per unit time of each and every transition .
