They can be used to contain cellular waste and to isolate materials that may be harmful to the cell.
Answer:
Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.
Explanation:
Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure
When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.
In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.
Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.
Answer: The main function of the rostrum is to bore holes in plants. In these holes, the female lays her eggs. The eggs hatch into larvae, which eat the plant material surrounding them. If this material is a crop plant or seeds used for human food, the weevils may cause serious damage.
