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.

<span>Personal space is practically universal concept familiar to all humans. Its basis is biological but depends heavily on cultural factors. In chilly Scandinavia, people prefer a good deal of personal space. It is not uncommon to see people at a bus stop two meters apart. In contrast, other places like Italy see physical closeness and contact as an important part of developing and maintaining social bonds.</span>
Answer:
The question is not complete has some details are missing. I have however attached a similar question for the differential equation, you can use the same approach for any DE.
Explanation:
Solution of differential equation was aplied to get the particular solution, the details and appropriate steps is as shown in the attachment.
Answer:
These two statements are true:
3 The North Pole is tilted away from the sun. - When it is summer in the Southern Hemisphere, the South Pole is tilted toward the sun, and North Pole is tilted away from the sun. The South Pole has a 24 hour day, while the North Pole has a 24 hour night.
4It is winter in the Northern Hemisphere. - When it is summer in the Southern Hemisphere, it is winter in the Northern Hemisphere, and viceversa. This is why Christmas in Canada is in winter, while Christmas in Australia is in summer.
The letter that identifies the country of Napol is N.
