Answer:
True
Explanation:
One of the edocrine processes the kidney is involved in is called the RAAS (Renin-Angiotensin-Aldosterone System) which is a signaling pathway involved in blood pressure control. It involves a number of hormones:
Angiotensinogen is produced by the liver in response tovarious inflammatory proteins
Renin is a protease produced by the kidneys in response tohypotension,
Angiotensin II increases blood pressure via a number of mechanisms:
Aldosterone acts to increase reabsorption of Na+ and water and increase elimination of K+ and H+ in the distal tubules of the kidneys for ion concentration maintenance
Answer:
The answer is B. The cell divides once to form two identical cells.
Explanation:
Action potential is a mechanism of transfer of ions across the plasma membrane down their elctrochemical gradient. Action potential is regenerated by the influx of ions such as sodium in case of voltage gated sodium channels. The voltage gated channels can be either open or closed depending on the action potential. Depolarization of membrane leads to the opening of these channels that allow the sodium ions to enter the cell down their electrochemical gradient. The threshold of action potential is reached when the entry of sodium ions out reach the exit of potassium ions from the cell. This leads to the generation of action potential.
The eye bends light through the Cornea; which does the majority of the bending of the light, and the Lens, which fine tunes the light.
