A cell membrane pump helps human cells to maintain a relatively constant sodium and potassium concentration.
<u>Option: A</u>
<u>Explanation:</u>
Sodium potassium pump is a plasma membrane protein that utilizes energy ATP — Triphosphate Adenosine turning into ADP — Adenosine Diphosphate to deliver intracellular and extracellular sodium (NA+) and potassium (K+) ions sequentially. The purpose of this entire mechanism is to preserve cell equilibrium.
The extracellular medium has a greater concentration of Na while the K concentration of the intracellular fluid is lower. Proteins trap sodium ions in the cytoplasm and pump them out from the cells to preserve cell stability while preserving concentrations. Within the cells proteins inject potassium ions into the cell.
Answer:
c. Increased reabsorption of phosphate in the kidneys
d. Increased deposition of calcium into the bones.
Explanation:
Hyperphosphatemia is a condition that is expressed particularly in people with a kidney dysfunction. It comprises the kidneys, which do not excrete enough phosphate from the body as they reabsorbe it and thus leading to increased phosphate levels.
Also, phosphate binds calcium with high affinity, provoking acute hypocalcemia (decreased levels of calcium). In Hyperphosphatemia, calcium is being deposited mostly in the bone but also in the extraskeletal tissue.
It’s B genetically engineered trees could have unexpected interactions with organisms of natural ecosystems.
The answer is, "It has membrane-bound organelles."
The correct answer is nucleus
