Answer:thanks for the points
Explanation:have a good day
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: B.
Neuroticism
Explanation:
This is a condition that put someone in a negative and anxious emotional state. It's not a medical condition but a personality trait. People with this condition suffer from depression, guilt, anger and anxiety.
Frailty in the elderly is defined as a condition of overall physiological reserve impairment that is functional disabilities affecting several organ systems.
<h3> Functional Disabilities in Old Age</h3>
- Increased sensitivity, a reduced ability to tolerate internal and external stresses, and a constrained ability to maintain physiological and psychosocial equilibrium are all signs of fragility.
- Changes in the nervous system, include decreased cerebral activity, diminished motor and sensory function of peripheral nerves, and altered autonomic function, including regulation of temperature and heart rate.
- Six functional disability classifications include severe cognitive impairment, hearing impairment, mental
- Senescence causes functional alterations in the gastrointestinal system, mostly due to changed motility patterns, and atrophic gastritis and altered hepatic drug metabolism are frequent in the elderly.
- Any issue with self-care and independent living, as well as opulence and vision.
