Can molecules made from the same atom form ionic bonds. Why?
Digiron [165]
No. Ionic bonds form when atoms with opposite charges bond with one another. Atoms develop charges by gaining or losing electrons. For a given element, the atoms will (usually) have a tendency to gain OR lose a particular number of electrons, so they can only form ions of a particular charge that is either positive or negative.

Parathyroid hormone is the major regulator of the plasma concentration of__________ ions
photoshop1234 [79]

Answer:

Calcium

Explanation:

Parathyroid hormone (PTH) is a hormone that is secreted by the parathyroid gland. It is the major regulator of the plasma concentration of calcium ions. It regulates calcium ions in the kidney, intestine and bones.

In the kidney, is involved in the re-absorption of calcium in distal ducts and the renal collecting duct, it is also involved in activating the conversion of 25-hydroxy vitamin D into 1,25-dihydroxy vitamin D (calcitriol).

In the intestine,  PTH is involved in the absorption of calcium, by increasing vitamin D production.

In the bone, it helps in regulating calcium levels; when serum calcium level is low, PTH stimulates the activity of the osteoclast, to produce more calcium.
