Answer:
b. cause an increase in blood pH.
Explanation:
Carbonic anhydrases are zinc-containing enzymes that catalyze the reversible reaction of conversion between CO2 and bicarbonates (carbon dioxide hydration and bicarbonate dehydration). The conversion of bicarbonate to CO2 facilitates its entry into the cell. On the other hand, the conversion of CO2 to bicarbonate helps keep the CO2 inside the cell.
This enzyme is important in all living organisms for maintenance of acid-base balance (regulates pH ). For example, carbonic anhydrases lowers pH in the stomach by producing an acid.
The wind makes pollination possible for gymnosperms. In gymnosperms ovaries are absent and the gametophytes of these plants are present on cones rather than flowers. Unlike angiosperms that get pollinated with animal interference, wind plays a crucial role in gymnosperm pollination.
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.
I am sure the answer is repel because human hair carries negative charges which mean they will repel because like things repel
