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: the example that is meaningful is the gender pay gap that is when a woman is pay less than a man for the same job.
Explanation: Feminization of poverty is a phenomenon referring to the widening gap between women and men caught in a sequence of economic deprivation and scarcity. This phenomenon is not only a consequence of lack of income, but is also the outcome of the deprivation of capabilities and gender biases present in both societies and governments. It covers the poverty of choices and chances such as the ability to lead a long, healthy, and creative life, and having basic rights like freedom, respect, and dignity.
Answer:
B. The second most abundant ingredient by weight.
Explanation:
The ingredients written in the ingredient label are written in ascending order of abundance present in that product.All the quantities written on the ingredient label are measured by weight.
So if the olive oil is written on the second number it means that the olive oil is the second most abundant ingredient in that product by weight.

Answer:</h3>
C. A high school math teacher who encouraged his own son to skip college and focus on learning a trade to "save all that wasted tuition money"
<h3>
Explanation:</h3>
The reason why answer choice "C. A high school math teacher who encouraged his own son to skip college and focus on learning a trade to 'save all that wasted tuition money'" would be the correct answer because the high school teacher would have a "cognitive dissonance" in his response.
Cognitive dissonance is is having 2 or multiple beliefs in a topic, in this case, the high school teacher would have 2 beliefs in the topic of higher education.
The high school teacher believes that higher education is very important and that people need to get a higher education, but he tells his own son that the tuition that is going into college is "wasted money." This shows that the high school teacher has cognitive dissonance because he has two different beliefs. He believes that higher education is very important, but doesn't want his own son to pursue it because of the tuition costs.
