Accretion is a process by which material is added to a tectonic plate or a landmass. This material may be sediment, volcanic arcs, seamounts or other igneous features. There are two types of geologic accretion—plate accretion and landmass accretion. The Plate accretion involves the addition of material to a tectonic plate. The Landmass accretion involves the addition of sediment to a coastline or riverbank, increasing land area.

Answer: Kidneys, intestine and skeletal system
Explanation:
Parathyroid hormone is the hormone that is responsible for regulation of the calcium levels in the extracellular fluid in the body.
It exerts influence over the skeletal system to reabsorb the calcium by the oesteoclasts. It causes the reabsorption of the calcium by the small intestine. It also prevents the excretion of calcium through urine by reabsorption by renal tubules.
When voltage of a plasma membrane shifts from +30mV towards 0mV, we say cell is repolarizing. Repolarization results from the movement of positively charged K+ ions out of the cell. This repolarization phase of an action potential results in hyperpolarization, attainment of a membrane potential that is more negative than the resting membrane potential.
