Meiosis is a special type of cell division in sexually-reproducing organisms used to produce the gametes, such as sperm or egg cells.
Answer:
second messenger cascade
Explanation:
Second messenger cascade is activated by the NE beta receptor which then activates the G protein. G protein in turn activates the enzyme responsible for converting ATP to cAMP i.e adenylyl cyclase. When the level of cAMP reaches a certain level, the enzyme protein kinase is released. The enzyme phospholipase is released as the G proteins get active and breaks down the phospholipid membrane into two secondary messenger molecule.
Answer:
D.) Water is recovered.
Explanation:
Large intestine is a part of alimentary canal. The food gets digested by the time it reaches here. So large intestine has no role in digestion. Its main function is to absorb water from the remaining undigested food matter so that solid stool can be produced and wastes be eliminated from the body. The absorbed water is returned to the body and reutilized.
Large intestine has a lining of mucosa which has tiny indentations called as crypts of Lieberkühn. They have many glands and goblets cells that are involved in absorption of fluids and secretion.
Answer:
Explanation:Mitosis gives identical cells to each other and to the mother cell, while meiosis leads to genetic variation due to crossing over and independent assortment. Mitosis gives nuclei with the same number of chromosomes as the mother cell while meiosis gives cells with half the number
