Problem: - The kidneys receive blood from the renal artery - They process it with millions of tiny nephrons - Remove all the waste - The kidneys return the blood back to the body through the renal artery What might be the last step of the process?

A: Send the urine with the waste to the bladder through the ureters.

Problem: - A red giant burns mass - This mass creates high core temperatures - The mass decreases - The red giant can no longer fuse the carbon and oxygen in its center - The gravity of the star can no longer hold the outside layers - The layers break away - Only the inner core remains What might be the last step of the process?

A: This inner core is known as a white dwarf.

Problem: - A star burns in space - Eventually it burns all its hydrogen - Becomes a red giant - Once the red giant burns itself out - The core of the star collapses - The gasses will start to disperse - Only the core is left What might be the last step of the process?

A: A white dwarf has been formed.
