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.

Answer:
Britain also needed money to pay for its war debts. The King and Parliament believed they had the right to tax the colonies. They decided to require several kinds of taxes from the colonists to help pay for the French and Indian War. The colonists started to resist by boycotting, or not buying, British goods.
Explanation:
Answer:
Post Conventional.
Explanation:
In agreement with the Piaget's theory of moral development, Kohlberg developed the theory of the Kohlberg's Stages of Moral Development.
<u>This theory categorised the development of morality in three levels namely Pre-conventional, Conventional, and post-conventional morality</u>.
In the given case, Kai is at the post-conventional morality stage.
In this stage, the morality of the individual is based on self-chosen principles. Their morals are grounded on the principles of rights and justice.
The morals of Kai are based on the principle of rights and justice and thus is an example of post-conventional morality.
