Answer:
A desirable intake of dietary fiber is 20-35 grams daily, according to the American Dietetic Association.
Explanation:
Dietary fiber has always been a part of a healthy, balanced eating lifestyle. Fiber has 2 types, soluble and insoluble. Soluble fiber is a <u>gelatin-like</u> substance when combined with water and when ingested, <u>can help slow the travel of food in the gut, making you feel</u> <em>"full."</em> Insoluble fiber or roughage is the <u>bulk-forming type</u>. It <u>holds water</u> in its structure, helping <u>regulate the bowel movements.</u>
Fiber, being a <u>complex carbohydrate</u>, can help <u>lessen the risk of an increase of bad cholesterol and blood sugar</u>. Examples of fiber-rich foods are whole grain products, barley, oats, grapes, etc.
The sister chromatids are then pulled apart by the mitotic spindle which pulls one chromatid to one pole and the other chromatid to the opposite pole.
The chromosomes line up neatly end-to-end along the centre (equator) of the cell.
The centrioles are now at opposite poles of the cell with the mitotic spindle fibres extending from them.
The mitotic spindle fibres attach to each of the sister chromatids.
The DNA in the cell is copied in preparation for cell division, this results in two identical full sets of chromosomes?.
Outside of the nucleus? are two centrosomes, each containing a pair of centrioles, these structures are critical for the process of cell division.
