A warm spell during the Ice Age gave early humans a route out of Africa 20,000 years earlier than thought, say scientists who've uncovered a prehistoric tool kit in Arabia. ... Seas in the region would still have been at relatively low, Ice Age levels, making for shorter crossings.

List the order the steps of the path of blood through the kidneys.
Alexxandr [17]

Blood flows to the kidneys through the right and left renal arteries. Inside each kidney these branch into smaller arterioles.

The blood is at very high pressure and flows through the arterioles into tiny knot of vessels called the Glomerulus. These are located in the nephrons.

From the glomerulus the blood pressure drops and the blood flows into arterioles which coil around the nephrons. These in turn connect to a series of small veins. These vessels reunite and ultimately form the renal vein.

About one quarter of the total cardiac output (or total blood flow) circulates through the kidneys. This equates to just over 1 litre of blood every minute.

Hope this helps (:

In your own words, explain the processes responsible for the formation of a reverse fault.
zzz [600]
Reverse faults are exactly the opposite of normal faults. If the hanging wall rises relative to the footwall you have a reverse fault. Reverse faults occur in areas undergoing compression. If you imagine undoing the motion of a reverse fault, you will undo the compression and thus lengthen the horizontal distance between two points on either side of the fault.
if you stood on the fault plane the block on the right would be under your feet. this is thus the footwall. The tan sandstone has been pushed up and over itself. This offset of the hanging wall indicates that this is a reverse fault.
