Unique or damaging plate edges cause volcanoes. As the more thick plate subducts, it will dissolve at profundity and the water is driven off, will bring down the liquefying purpose of the overlying mantle wedge, this will make a kind of magma. Volcanic Island Arcs are framed at maritime dangerous plate edges. The hot, light magma, is less thick that the encompassing rock so will ascend to the surface, and will gather underneath the plate that hasn't been subducted. It will then, under expanded weight eject under the ocean. More than thousands of a great many years, it will continue emitting, to shape islands.

Answer:
c. Left atrium
j. right atrium
f. left ventricle
g. right ventricle
Explanation:
The heart consists of four chambers that is two ventricles and two articles.
Blood enters the right atrium goes into the right ventricle.
The right ventricle then pumps blood into the lungs where the blood gets oxygenated.
Pulmonary vein then brings back the blood from lungs into the left ventricle, blood is pumped into the left atrium and out of the heart.
That is the process through which blood navigates in the heart.
Answer:
Heart muscles have long refractory period.
Explanation:
Heart muscle cells cannot rely on fermentation for long period of time because heart muscles have long refractory period which does not allow it to use the fermentation process. They have rich blood supply and have capillary density 4 times more than normal skeletal muscles. The anaerobic capacity is limited in the heart which does not allow the heart muscle cells to use fermentation process for metabolism. Our heart requires oxygen in large amount and very quickly for ATP production.
