Answer:
Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.
Explanation:
Meiosis consist of two successive divisions while mitosis has one cell division. Mitosis occurs in the general body cells resulting in growth while meiosis is the process that occurs during the formation of sex cells. Mitosis results in diploid two daughter cells that are identical to one another and to the parent. Meiosis results in haploid daughter cells each containing half the number of chromosomes as compared to the parent cell.
Answer:
Función. Las células de Schwann funcionan como aislante eléctrico, mediante la mielina. Este aislante, que envuelve al axón, provoca que la señal eléctrica lo recorra sin perder la intensidad, facilitando que se produzca la denominada conducción . saltatoria.
Answer: Option A.
Transverse tubules rapidly move the action potential to the interior of the muscle potential.
Explanation:
Transverse tubules are cylindrical pockets found in the plasma membrane of muscle cells. They are formed from phospholipid bilayer or sarcolemma of skeletal or cardiac muscle cells. They have membrane that have large concentration of ion channels,transporters and pump. They permit action potention into the cell and also to a particular structure sarcuplasmic reticulum. They play a role in regulating cellular calcium concentration.
