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.

Explanation:
Answer: A. Ways a person can become a US citizen.
Further detail:
- Anyone born within the borders of the United States is considered a US citizen by birth. This is even true if the parents of the child born in the US are not citizens. Being born on US soil is a way a child is considered a US citizen. This has become a matter of some contention in recent years, as some opponents of illegal immigration accuse immigrants of coming across the border to have a baby just so that baby can have US citizenship.
- If either of a set of parents are US citizens, a child born to those parents is also a US citizen, even if you were born in a foreign country. So if parents are stationed overseas or traveling, and a birth occurs outside the United States, that child still has US citizenship.
- For those not citizens by being born on US soil or to a US citizen parent, applying to become a naturalized citizen is the path for pursuing citizenship. On the USA.gov website, you can find a full desciption of "How to Apply for US Citizenship" and the naturalization process.
The four archetypes
The Persona
The persona is how we present ourselves to the world. The word "persona" is derived from a Latin word that means "mask." It is not a literal mask, however.
The persona represents all of the different social masks that we wear among various groups and situations. It acts to shield the ego from negative images. According to Jung, the persona may appear in dreams and take different forms.
The Shadow
The shadow is an archetype that consists of sex and life instincts. The shadow exists as part of the unconscious mind and is composed of repressed ideas, weaknesses, desires, instincts, and shortcomings.
The shadow forms out of our attempts to adapt to cultural norms and expectations. It is this archetype that contains all of the things that are unacceptable not only to society but also to one's own personal morals and values. It might include things such as envy, greed, prejudice, hate, and aggression.
The Anima or Animus
The anima is a feminine image in the male psyche, and the animus is a male image in the female psyche.5 The anima/animus represents the "true self" rather than the image we present to others and serves as the primary source of communication with the collective unconscious.
The Self
The self is an archetype that represents the unified unconsciousness and consciousness of an individual.
Creating the self occurs through a process known as individuation, in which the various aspects of personality are integrated. Jung believed that disharmony between the unconscious and the conscious mind could lead to psychological problems. Bringing these conflicts into awareness and accommodating them in conscious awareness was an important part of the individuation process.
