Can anyone please explain the mechanism of concentration of the filtrate. |
| Answer» A\xa0counter-current mechanism system\xa0is a\xa0mechanism\xa0that expends energy to create a concentration gradient. ... For example, it can refer to the process that is underlying the process of urine concentration, that is, the production of hyperosmotic urine by the mammalian kidney. The\xa0counter-current mechanism\xa0takes place in Juxtamedullary\xa0nephron. The function of the\xa0counter-current multiplier\xa0is to produce the hyperosmotic Medullary Interstitium. The ADH promotes water reabsorption through the walls of the distal convoluted tubule and collecting duct. Mammals have the ability to produce concentrated urine. The Henle\'s loop and vasa recta plays significant role in concentrating urine. The flow of\xa0filtrate\xa0in two limb of Henle\'s loop and blood flow in two limbs of vasa recta are in opposite direction hence form counter current. | |

Expand G1S and G2M |
| Answer» The\xa0S phase\xa0of a cell cycle occurs\xa0during\xa0interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.\xa0Between G1 and S phase, three DNA damage checkpoints occur to ensure proper growth and synthesis of DNA prior to cell division. Damaged DNA during\xa0G1, before entry into\xa0S phase, and during\xa0S phase\xa0result in the expression of ATM/R protein.\xa0Interphase is divided into the first growth (G1), Synthesis (S), and the second growth (G2) phases (figure 1). The growth phases are, as you may have suspected, for the growth of the cell, during the synthesis phase the DNA replication occurs in preparation for the second growth phase. | |
