Answer:

The correct option is A. Diffusion

Explanation:

Diffusion can be described as a mechanism through which molecules move along the concentration gradient i.e from an area of higher concentration to an area of lower concentration. This process does not require energy as the molecules or ions move along the concentration gradient.

Hence, the pumping excess sodium ions by the cell membrane to an area where the concentration of sodium is less would be an example of diffusion.

What pathologic change occurs to the kidneys glomeruli as a result of hypertension?
shusha [124]
<span>Interstitial fibrosis and glomeruli tubular atrophy are pathological effects of hypertension on kidneys. This is especially as a result of hyalinization that results in sclerosis to the glomeruli which may ultimately lead to kidney failure if unmanaged. The hyaline accumulate in the nephron tubules resulting in protein in urine. The plaque build up in the kidneys, as a result, causes glomerular ischemia   </span>
