Answer:
Some sodium channels have been inactivated and cannot be reopened immediately.
Explanation: A stimuli is a term used to describe any sensation on a living organism such as plants or animals which is likely to create a form of response or responses by that living organism.
Sodium channels are specifically connected with stimuli transfer, once the intervals between stimuli decrease it will affect the response provided as the sodium channels may not be able to reopen immediately in order to manage the next stimuli.
Microvilli are the tiny projections in the cell lining the villi. It increases the surface area of absorption thereby increasing absorption.
Microvilli on the surface of epithelial cells such as those lining the intestine increase the cell’s surface area and thus facilitate the absorption of ingested food and water molecules. Microvilli are also sometimes called the intestinal brush border.
The combination of circular folds, villi and microvilli helps absorption by increasing the surface area of the small intestine by 30 to 600 times.
<h3>
Where the Brush border of small intestine cells is formed ?</h3>
The innermost layer lining the lumen of the alimentary canal is the mucosa. This layer forms irregular folds (rugae) in the stomach and small finger-like folding called villi in the small intestine.
The cells lining the villi produce numerous microscopic projections called microvilli giving a brush border appearance found on the apical surface of some epithelial cells. These modifications increase the surface area enormously and help in secretion and absorption.
Microvilli are covered in the plasma membrane, which encloses cytoplasm and microfilaments. Though these are cellular extensions, there are little or no cellular organelles present in the microvilli. Hence, the brush border of small intestine cells is formed of microvilli.

From the first row of the table, at a price of $10, suppliers are not willing to make any shoes (quantity supplied of shoes = 0) since they will not make significant profit off of it.
In contrast, the demand is 500, since everyone would love to buy shoes at that very cheap price.
