Why do volcanoes occur

Biology
2 answers:
Fantom [35]3 years ago

Volcanoes occur because of the position of the crust over a plate boundary or a 'hot spot' in the Earth's mantle. Continental volcanoes form when subducted crust melts to magma against the mantle, then is forced upward under pressure through cracks in the rocks above.

What is the primary function of the juxtaglomerular complex?
Vsevolod [243]

Answer:

Juxtaglomenular is a structure in the kidney which regulates the function of each nephron, the functional units of the kidney. The main function of the  juxtaglomerular cells is to secrete renin in response to:

Stimulation of the beta-1 adrenergic receptor

Decrease in renal perfusion pressure (detected directly by the granular cells)

Decrease in NaCl concentration at the macula densa, often due to a decrease in glomerular filtration rate

Explanation:

The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and a structure in the kidney that regulates the function of each nephron, the functional units of the kidney.

Sweat is the result of which life function?
telo118 [61]
<span>Human sweat is a result of our body getting over heated. We sweat through our pores so our temperatures don't go up and as a result we stay at a normal temperature. We may feel hot but that's because we are hot from the heat of something. If we didn't sweat then our temperature would become very high and we would die.</span>
