<span>Potassium is actively transported into and out of the vacuoles in the guard cells.

There are different kind of potassium transport channels (KAT1, KAT2) that transport K+ inside and outside the vacuole of the guard cell, by the use of ATP (energy) and H+.</span>

<span>Potassium is actively transported into and out of the vacuoles in the guard cells. The sodium-potassium pump is responsible for the process of moving sodium and potassium ions across the cell membrane which is an active transport process involving the hydrolysis of ATP to provide necessary energy required. Accumulation of potassium ions in the guard cells causes turgidity which keeps the stomata open.</span>

What information would be most relevant to determining the time of death?

Nuetrik [128]

Lividity can be defined as the typical bluish-purple discoloration of the skin after death. Rigor mortis can be defined as the postmortem state in which the muscles become stiff.

After death, the stomach contains identifiable ingested foods within two hours.

Rigor mortis is characterized by the stiffening of the body after death, which is caused by the absence of ATP in muscle tissues.

Postmortem lividity or livor mortis is caused by the accumulation of blood in blood vessels (the lack of arterial pressure) as a result of gravity.

The most relevant information to determine the time of death is the presence of lividity, rigor mortis, and/or stomach contents (Option c).

lisov135 [29]

Answer:

C. Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.

Explanation;

Aldosterone hormone is produced by the adrenal gland and mainly carries out its functions in the kidney.Through the aldosterone hormone the body is able to retain more water for the kidney is able to hold more sodium.
When the plasma sodium levels decrease and the plasma potassium levels increase the production of aldosterone hormone is stimulated for sodium is needed in the .body to maintain the high water levels in the body.
